Virtualization Wars: Episode V – VMware Strikes Back

July 12th, 2011

Snagit CaptureAt 9am PDT this morning, Paul Maritz and Steve Herrod take the stage to announce the next generation of the VMware virtualized datacenter.  Each new product and set of features are impressive in their own right.  Combine them and what you have is a major upgrade of VMware’s entire cloud infrastructure stack.  I’ll highlight the major announcements and some of the detail behind them.  In addition, the embargo and NDA surrounding the vSphere 5 private beta expires.  If you’re a frequent reader of blogs or the Twitter stream, you’re going to bombarded with information at fire-hose-to-the-face pace, starting now.

vSphere 5.0 (ESXi 5.0 and vCenter 5.0)

At the heart of it all is a major new release of VMware’s type 1 hypervisor and management platform.  Increased scalability and new features make virtualizing those last remaining tier 1 applications quantifiable.

ESX and the Service Console are formally retired as of this release.  Going forward, we have just a single hypervisor to maintain and that is ESXi.  Non-Windows shops should find some happiness in a Linux based vCenter appliance and sophisticated web client front end.  While these components are not 100% fully featured yet in their debut, they come close.

Storage DRS is the long awaited compliment to CPU and memory based DRS introduced in VMware Virtual Infrastructure 3.  SDRS will coordinate initial placement of VM storage in addition to keeping datastore clusters balanced (space usage and latency thresholds including SIOC integration) with or without the use of SDRS affinity rules.  Similar to DRS clusters, SDRS enabled datastore clusters offer maintenance mode functionality which evacuates (Storage vMotion or cold migration) registered VMs and VMDKs (still no template migration support, c’mon VMware) off of a datastore which has been placed into maintenance mode.  VMware engineers recognize the value of flexibility, particularly when it comes to SDRS operations where thresholds can be altered and tuned on a schedule basis. For instance, IO patterns during the day when normal or peak production occurs may differ from night time IO patterns when guest based backups and virus scans occur.  When it comes to SDRS, separate thresholds would be preferred so that SDRS doesn’t trigger based on inappropriate thresholds.

Profile-Driven Storage couples storage capabilities (VASA automated or manually user-defined) to VM storage profile requirements in an effort to meet guest and application SLAs.  The result is the classification of a datastore, from a guest VM viewpoint, of Compatible or Incompatible at the time of evaluating VM placement on storage.  Subsequently, the location of a VM can be automatically monitored to ensure profile compliance.

7-10-2011 5-29-56 PM

Snagit CaptureI mentioned VASA previously which is a new acronym for vSphere Storage APIs for Storage Awareness.  This new API allows storage vendors to expose topology, capabilities, and state of the physical device to vCenter Server management.  As mentioned earlier, this information can be used to automatically populate the capabilities attribute in Profile-Driven Storage.  It can also be leveraged by SDRS for optimized operations.

The optimal solution is to stack the functionality of SDRS and Profile-Driven Storage to reduce administrative burden while meeting application SLAs through automated efficiency and optimization.

7-10-2011 7-34-31 PM

Snagit CaptureIf you look closely at all of the announcements being made, you’ll notice there is only one net-new release and that is the vSphere Storage Appliance (VSA).  Small to medium business (SMB) customers are the target market for the VSA.  These are customers who seek some of the enterprise features that vSphere offers like HA, vMotion, or DRS but lack the fibre channel SAN, iSCSI, or NFS shared storage requirement.  A VSA is deployed to each ESXi host which presents local RAID 1+0 host storage as NFS (no iSCSI or VAAI/SAAI support at GA release time).  Each VSA is managed by one and only one vCenter Server. In addition, each VSA must reside on the same VLAN as the vCenter Server.  VSAs are managed by the VSA Manager which is a vCenter plugin available after the first VSA is installed.  It’s function is to assist in deploying VSAs, automatically mounting NFS exports to each host in the cluster, and to provide monitoring and troubleshooting of the VSA cluster.

7-10-2011 8-03-42 PM

Snagit CaptureYou’re probably familiar with the concept of a VSA but at this point you should start to notice the differences in VMware’s VSA: integration.  In addition, it’s a VMware supported configuration with “one throat to choke” as they say.  Another feature is resiliency.  The VSAs on each cluster node replicate with each other and if required will provide seamless fault tolerance in the event of a host node failure.  In such a case, a remaining node in the cluster will take over the role of presenting a replica of the datastore which went down.  Again, this process is seamless and is accomplished without any change in the IP configuration of VMkernel ports or NFS exports.  With this integration in place, it was a no-brainer for VMware to also implement maintenance mode for VSAs.  MM comes in to flavors: Whole VSA cluster MM or Single VSA node MM.

VMware’s VSA isn’t a freebie.  It will be licensed.  The figure below sums up the VSA value proposition:

7-10-2011 8-20-38 PM

High Availability (HA) has been enhanced dramatically.  Some may say the version shipping in vSphere 5 is a complete rewrite.  What was once foundational Legato AAM (Automated Availability Manager) is now finally evolving to scale further with vSphere 5.  Some of the new features include elimination of common issues such as DNS resolution, node communication between management network as well as storage along with failure detection enhancement.  IPv6 support, consolidated logging into one file per host, enhanced UI and enhanced deployment mechanism (as if deployment wasn’t already easy enough, albeit sometimes error prone).

7-10-2011 3-27-11 PMFrom an architecture standpoint, HA has changed dramatically.  HA has effectively gone from five (5) fail over coordinator hosts to just one (1) in a Master/Slave model.  No more is there a concept of Primary/Secondary HA hosts, however if you still want to think of it that way, it’s now one (1) primary host (the master) and all remaining hosts would be secondary (the slaves).  That said, I would consider it a personal favor if everyone would use the correct version specific terminology – less confusion when assumptions have to be made (not that I like assumptions either, but I digress).

The FDM (fault domain manager) Master does what you traditionally might expect: monitors and reacts to slave host & VM availability.  It also updates its inventory of the hosts in the cluster, and the protected VMs each time a VM power operation occurs.

Slave hosts have responsibilities as well.  They maintain a list of powered on VMs.  They monitor local VMs and forward significant state changes to the Master. They provide VM health monitoring and any other HA features which do not require central coordination.  They monitor the health of the Master and participate in the election process should the Master fail (the host with the most datastores and then the lexically highest moid [99>100] wins the election).

Another new feature in HA the ability to leverage storage to facilitate the sharing of stateful heartbeat information (known as Heartbeat Datastores) if and when management network connectivity is lost.  By default, vCenter picks two datastores for backup HA communication.  The choices are made by how many hosts have connectivity and if the storage is on different arrays.  Of course, a vSphere administrator may manually choose the datastores to be used.  Hosts manipulate HA information on the datastore based on the datastore type. On VMFS datastores, the Master reads the VMFS heartbeat region. On NFS datastores, the Master monitors a heartbeat file that is periodically touched by the Slaves. VM availability is reported by a file created by each Slave which lists the powered on VMs. Multiple Master coordination is performed by using file locks on the datastore.

As discussed earlier, there are a number of GUI enhancements which were put in place to monitor and configure HA in vSphere 5.  I’m not going to go into each of those here as there are a number of them.  Surely there will be HA deep dives in the coming months.  Suffice it to say, they are all enhancements which stack to provide ease of HA management, troubleshooting, and resiliency.

Another significant advance in vSphere 5 is Auto Deploy which integrates with Image Builder, vCenter, and Host Profiles.  The idea here is centrally managed stateless hardware infrastructure.  ESXi host hardware PXE boots an image profile from the Auto Deploy server.  Unique host configuration is provided by an answer file or VMware Host Profiles (previously an Enterprise Plus feature).  Once booted, the host is added to vCenter host inventory.  Statelessness is not necessarily a newly introduced concept, therefore, the benefits are strikingly familiar to say ESXi boot from SAN: No local boot disk (right sized storage, increased storage performance across many spindles), scales to support of many hosts, decoupling of host image from host hardware – statelessness defined.  It may take some time before I warm up to this feature. Honestly, it’s another vCenter dependency, this one quite critical with the platform services it provides.

For a more thorough list of anticipated vSphere 5 “what’s new” features, take a look at this release from virtualization.info.

 

vCloud Director 1.5

Snagit CaptureUp next is a new release of vCloud Director version 1.5 which marks the first vCD update since the product became generally available on August 30th, 2010.  This release is packed with several new features.

Fast Provisioning is the space saving linked clone support missing in the GA release.  Linked clones can span multiple datastores and multiple vCenter Servers. This feature will go a long way in bridging the parity gap between vCD and VMware’s sun setting Lab Manager product.

3rd party distributed switch support means vCD can leverage virtualized edge switches such as the Cisco Nexus 1000V.

The new vCloud Messages feature connects vCD with existing AMQP based IT management tools such as CMDB, IPAM, and ticketing systems to provide updates on vCD workflow tasks.

vCD originally supported Oracle 10g std/ent Release 2 and 11g std/ent.  vCD now supports Microsoft SQL Server 2005 std/ent SP4 and SQL Server 2008 exp/std/ent 64-bit.  Oracle 11g R2 is now also supported.  Flexibility. Choice.

vCD 1.5 adds support for vSphere 5 including Auto Deploy and virtual hardware version 8 (32 vCPU and 1TB vRAM).  In this regard, VMware extends new vSphere 5 scalability limits to vCD workloads.  Boiled down: Any tier 1 app in the private/public cloud.

Last but not least, vCD integration with vShield IPSec VPN and 5-tuple firewall capability.

vShield 5.0

VMware’s message about vShield is that it has become a fundamental component in consolidated private cloud and multi-tenant VMware virtualized datacenters.  While traditional security infrastructure can take significant time and resources to implement, there’s an inherent efficiency in leveraging security features baked into and native to the underlying hypervisor.

Snagit Capture

There are no changes in vShield Endpoint, however, VMware has introduced static routing in vShield Edge (instead of NAT) for external connections and certificate-based VPN connectivity.

 

Site Recovery Manager 5.0

Snagit CaptureAnother major announcement from VMware is the introduction of SRM 5.0.  SRM has already been quite successful in providing simple and reliable DR protection for the VMware virtualized datacenter.  Version 5 boasts several new features which enhance functionality.

Replication between sites can be achieved in a more granular per-VM (or even sub-VM) fashion, between different storage types, and it’s handled natively by vSphere Replication (vSR).  More choice in seeding of the initial full replica. The result is a simplified RPO.

Snagit Capture

Another new feature in SRM is Planned Migration which facilitates the migration protected VMs from site to site before a disaster actually occurs.  This could also be used in advance of datacenter maintenance.  Perhaps your policy is to run your business 50% of the time from the DR site.  The workflow assistance makes such migrations easier.  It’s a downtime avoidance mechanism which makes it useful in several cases.

Snagit CaptureFailback can be achieved once the VMs are re protected at the recovery site and the replication flow is reversed.  It’s simply another push of the big button to go the opposite direction.

Feedback from customers has influenced UI enhancements. Unification of sites into one GUI is achieved without Linked Mode or multiple vSphere Client instances. Shadow VMs take on a new look at the recovery site. Improved reporting for audits.

Other miscellaneous notables are IPv6 support, performance increase in guest VM IP customization, ability to execute scripts inside the guest VM (In guest callouts), new SOAP based APIs on the protected and recovery sides, and a dependency hierarchy for protected multi tiered applications.

 

In summary, this is a magnificent day for all of VMware as they have indeed raised the bar with their market leading innovation.  Well done!

The time for ESXi is now. The Susan Gudenkauf interview

July 5th, 2011

I suspect VMware is going to orchestrate the release of the next generation of vSphere with VMworld 2011 or perhaps even sooner.  There is a big media event coming up on Tuesday July 12th called Raising the Bar, Part V. I’m guessing announcements and details will be showcased at this event.  At any rate, most people have known for quite some time that VMware ESX is being retired in favor of ESXi as VMware’s flagship type 1, enterprise, scalable, datacenter hypervisor going forward.  This next version of vSphere which VMware is about to release officially marks the end of ESX.  Only ESXi will be available onward into the future.  For most people, this doesn’t mean a lot since many have already made the formal transition from ESX to ESXi.  However, others have yet to commit to ESXi for various reasons.  Those who have already embraced ESXi are prepared for this next release of vSphere and all of the new features that it brings.  Those on ESX still are Behind the Eight Ball.  With the upcoming version of vSphere, we will no longer have a choice to stay the course with ESX.  The time to make the transition to ESXi is becoming critical and that time is now. I had a chance to talk with Susan Gudenkauf who oversees the ESXi program and is helping customers make this transition.  Following is the interview.  If you’re still hesitant about ESXi, I hope this Q&A session helps.

Q. Can you please introduce yourself and tell us a little about your history at VMware?

A. My name is Susan Gudenkauf and I have been a VMware employee for 8 years. I started at VMware in June of 2003 when there were about 240 employees. My first role here was Senior Systems Engineer and there were only about 10 of us in the world. We are still a tight knit group and those guys are some of my best friends now. I stayed in that role for about 18 months and left when there was around 100 SE’s (me still being the only female in the group). I went on to become a Technical Account Manager (TAM) so I could concentrate on the relationships with my customers instead of the more ‘hit-and-run’ work I was doing as an SE. At the time the territories were a lot larger and I covered 6 states and 3 Canadian Provinces by myself. After I had been a TAM for a couple of years I was promoted to TAM Manager and then Senior Manager. In January of 2011 I left Professional Services (PSO) to oversee the ESXi program as a Senior Program Manager focusing on customer migration. It was a huge step outside of my comfort zone but it’s been a wonderful experience so far. I’ve really been enjoying my career at VMware and it’s been fun getting to do different roles and having varying responsibilities.

Q. You are a legend in VMware certification history. Would you mind sharing that story?

A. I think the word ‘legend’ is a bit much (although it is certainly flattering) but I agree there is definitely some vibe around the VCP #1 thing (VMware Certified Professional). It’s one of the strangest and sweetest things that have ever happened to me. I didn’t know at the time it would become such a big deal, but I regularly get people asking for my autograph and for me to take photos with them. It’s really funny and I’m finally starting to enjoy that people care enough about it to even mention it. The first time I took the VMware course (on ESX 1.5) there wasn’t a VCP exam yet. I was working as a consultant for a partner at the time, but ended up going to VMware about 8 months after the course. The first week I started at VMware I took the VMware ESX 1.52 course and this time they had a certification exam – which we had to write on PAPER. The worst part was that we didn’t find out if we passed or failed for 6 weeks or something. It was pretty nerve wracking. Later I found out that the two guys I was friends with in the class (Ferhan Khan and Michael Cambian) were VCP #2 and VCP #3. It’s funny how we all ended up the first three VCPs in the world.

Q. What is your primary responsibility in your current role?

A. One of the most important responsibilities of my role is to bring awareness to the fact that ESXi is the only VMware hypervisor going forward. In July 2010 we announced that VMware ESX was going away and the next major release would have ESXi as the only platform. It is amazing how many people didn’t realize that when I started with this program. It’s been a major focus for me for all of 2011. Most of what the team has been working on is at the ESXi Info Center here: http://www.vmware.com/products/vsphere/esxi-and-esx/

Q. VMware ESXi may be new to some readers. Can you talk about what ESXi is and provide some historical background on its development?

A. Introduced in 2007, ESXi is the most advanced hypervisor in the market today. It is a “bare-metal” hypervisor and is thinner, lighter, more secure and easier to manage than ESX. ESXi also has a great advantage over other hypervisors due to the fact that it has complete independence from an Operating System. This is key because the hypervisor is the foundation to your private or hybrid cloud and you need it to be solid.

Q. Is ESXi experimental or for non-production use? What is VMware’s support stance on ESXi?

A. ESXi is absolutely designed for production use. It is a fully featured hypervisor that delivers greater performance, reliability, security and scalability than ESX. It can be used to run any of the advanced features of vSphere in a multitude of use cases. In fact, ESXi is already used in Production by a large percentage of VMware customers. We do have an entry level product called VMware vSphere Hypervisor which is based on ESXi but has limited management capabilities and doesn’t give users the advanced features such as high availability, live migration, power management, automatic load balancing, etc. Our support stance on ESXi is the same as our other solutions. We have Production Support (24×7), Basic Support (normal business hours) and Per-Incident Support.

Q. What can you tell me about the adoption rate of ESXi since it’s release?

A. I don’t have specific numbers in front of me, but since ESXi was released in 2007 we had seen a fairly gradual uptick in adoption…until vSphere 4 was released. I think that was really the tipping point for mainstream adoption. An interesting thing to note is that a leading indicator of adoption is the number of downloads each product gets. We’ve seen a reversal of ESX downloads to where they only count for 20% of the overall downloads now whereas ESXi is 80%. That’s really great validation for the strategic direction we have chosen.

Q. Is there a features, support, hardware compatibility, scalability, or stability gap between ESX and ESXi platforms?

A. Interestingly I hear the statement from some people that ESXi “doesn’t have the same functionality” that ESX does. This may have been true at one time, but since ESXi 4.1 came out we’ve really had feature parity. ESXi 4.1 supports Boot from SAN, scripted installations, integrated Active Directory support among other features. You can also expect the scalability that you’ve grown accustomed to with ESX.

Q. ESXi has significantly smaller code base than ESX. How does this impact the effort and time required to deploy and patch ESXi vs. ESX and what does the reduced footprint mean from a security standpoint?

A. You are right about the smaller code base Jason. ESXi is built on less than 100MB of code, whereas ESX is built on over 2GB. That’s a significant savings in space and it brings with it greater reliability and stability. An additional benefit of less code and independence from an Operating System is a lower risk of bugs and other security vulnerabilities.

Q. Has ESXi boot from firmware really taken off? Are there any caveats there?

A. Our major OEM partners offer ESXi pre-installed on their servers due to continuing customer demand. These customers are very enthusiastic about the super-convenient delivery model – just rack the server, power it on and ESXi is up and running. These customers also love the fact that they can run ESXi without local storage which increases the reliability of the server. There really aren’t any caveats other than making sure to use a flash device that’s certified for use for ESXi. These can be obtained from the OEMs. In the future, we intend to provide even more ways to deploy ESXi so that the customer can choose what’s best for their environment.

Q. Some customers have raised software compatibility concerns. How is ESXi impacting the partner ecosystem and what efforts are in place to ensure a seamless migration for ESX shops?

A. I work pretty closely with the Eco-Engineering team regarding our partners and software compatibility. Our partners have known about this transition for years now and those that have not already transitioned their tools to be compatible with ESXi are working diligently to complete this in the near future.

Q. Is VMware offering any special incentives for ESXi purchases, upgrades, or migrations?

A. One of the things I felt adamant about when I took this role was that we needed a way to help our customers migrate to ESXi with the least amount of disruption. Awareness and education are critical to any successful plan. I worked with our VMware Education team to bring an online course to our customers and most importantly to make that course available at no cost to them. It was a little bit of an uphill battle in the beginning since not only did I want VMware to pick up the cost of creating the course, but also the cost of purchasing a number of ESXi eBooks. We are running a promotion now where those that take the course and fill out the survey at the end will get a free eBook while our supplies last. We do still have some eBooks left right now but supplies are running short since it has been a pretty popular promotion. Here is a link to the course so folks can take the course while we still have the ebooks: http://mylearn.vmware.com/mgrreg/courses.cfm?ui=www_edu&a=one&id_subject=23970

Q. Once vSphere.next is released as an ESXi only platform, how long will customers be supported on ESX?

A. VMware will offer 7 years of support from the general availability of a new Major Release. That means ESX 4.x will be supported 7 years from the date of general availability on our next major release. The 7 years of support is broken down into 5 years of General Support and 2 years of Technical Guidance following the end of the General Support.

Q. Futures: Is the ESXi the final frontier for the VMware virtualized datacenter/vCloud platform or are there more platform changes coming?

A. I don’t know that I would say anything in technology is the “final frontier”. I know that everything evolves and ESXi is the platform that brings greater efficiency, reliability and stability to virtualization. My whole philosophy on life is if we aren’t evolving, we are dying. The best part of that is VMware will continue to evolve and be a leader for virtualization and cloud infrastructure. Our company meetings are so cool since we get to see and hear ideas from some of the smartest people on the planet. We hear people say that they have no idea how some of these things are even possible, but when Steve Herrod (our CTO and Senior Vice President of R&D) says it can happen…it just does. It’s fun to be a part of that and watch ideas come to life. Now, as far as a discussion on futures goes I’ll go into detail on some really cool things coming up since I’m certain all of your readers are under NDA, right? OK, I’m kidding. I think we should get Steve to have that discussion.

Thank you for your time Susan!

Thanks so much for the interview Jason, it was an honor to be asked and I had a lot of fun with this. I hope your readers enjoy it!

New Diskeeper White Paper: Optimization of VMware Systems

June 28th, 2011

diskeeperDiskeeper Corporation reached out to me via email last week letting me know that they’ve released a new white paper on optimizing VMs.  I’m making the three page document available for download via the following link:

Best Practice Protocols: Optimization of VMware Systems (416KB)

Force a Simple VMware vMA Password

June 27th, 2011

VMware ESXi is mainstream.  If you’ve ever deployed a VMware vMA appliance to manage ESXi (or heck, even ESX for that matter), you may have noticed the enforcement of a complex password policy for the vi-admin account.  For example, setting a password of password is denied because it is based on a dictionary word (in addition to other morally obvious reasons).

6-27-2011 7-17-52 PM

However, you can bend the complexity rules and force a simple password after the initial deployment using sudo.  You’ll still be warned about the violation of the complexity policy but by using sudo, the policy is allowed to be bypassed by a higher authority:

sudo passwd vi-admin

6-27-2011 7-14-16 PM

This tip isn’t specific to VMware or the vMA appliance.  It is general *nix knowledge.  There is ample documentation available which discusses the password complexity mechanism in various versions of *nix.  Another approach to bypassing the complexity requirement would be to actually relax the requirement itself but this would impact other local accounts potentially in use on the vMA appliance which may still require complex passwords.  Using the sudo command will be faster and leaves the default complex security mechanism in place.

Tech Support Mode Warnings

June 23rd, 2011

After enabling Local Tech Support Mode on an ESXi host via the DCUI (Direct Console User Interface), a yellow balloon styled warning will be displayed in the vSphere Client:

The Local Tech Support Mode for the host has been enabled

Likewise, if you’ve enabled Remote Tech Support Mode via SSH, you’ll see:

Remote Tech Support Mode(SSH) for the host has been enabled

Snagit Capture

KB Article 1016205 describes this condition as a security measure.  Adhering to the warnings would be a best practice for a production or high risk environment.  However, for lab, development, or environments with adequate perimeter security, it may be desirable to have either or both modes enabled but the warnings throughout the vSphere Client aren’t welcomed.

The VMware KB article goes on to say that there is no way to eliminate the warnings while leaving Local or Remote Tech Support Mode enabled.

Disabling Remote Tech Support Mode (SSH) and Local Tech Support Mode is the only way to prevent this warning.

While there may not be be an advanced configuration exposed, rebooting the host eliminates the conditional warnings.  It has also been reported in the VMware community forums that restarting the hostd service also works as follows, but as a side effect, will likely and temporarily disconnect the host from a vCenter Server:

/etc/init.d/hostd restart

Xangati Packs More Power in Free VMware Management Tool

June 22nd, 2011

Press Release:

Xangati Packs More Power in Free VMware Management Tool

Expands Functionality of Xangati for ESX with Performance Health Engine for Any Given Host

Cupertino, CA – June 22, 2011 – Xangati, the recognized leader in infrastructure performance management, today announced that it has expanded the capabilities and power offered in its free VMware management tool, Xangati for ESX. Xangati for ESX now includes several features from its recently announced and patent-pending Performance Health Engine – a real-time health index that monitors the health of every object within the virtualized infrastructure and a key component of Xangati’s multi-host Xangati Virtual Infrastructure (VI) and Virtual Desktop Infrastructure (VDI) Dashboards. With the updated Xangati for ESX, virtualization managers now have an even clearer picture of their VM activity, as well as the ability to fully monitor a single ESX host – all at no cost.

“Xangati is continuously looking for ways to improve our infrastructure performance management solutions in order to provide the highest value to virtualization managers – and that objective is absolutely no different for our free Xangati for ESX tool,” said Alan Robin, CEO of Xangati. “The response to our Performance Health Engine – for both our VI and VDI dashboards – inspired us to incorporate some of its capabilities into our free tool, so that everyone can experience and benefit from real-time health analysis – in any stage of their virtualization initiative.”

“By incorporating its health index into the free Xangati for ESX, Xangati allows virtualization managers to create a baseline for the infrastructure,” said David Davis, vExpert and blogger. “When any unusual activity occurs on the infrastructure, the tool alerts you and identifies the problem area. This ability – plus Xangati’s trademark DVR recordings – provide for the most comprehensive troubleshooting available, differentiating Xangati from other virtual performance monitoring tools – all for free.”

New Capabilities Streamline Management and Ensure User Satisfaction

With its new enhancements, Xangati for ESX gives managers deeper insights into any potential problems within virtualized environments by immediately and visually alerting them to any anomalies. Xangati achieves this unique health alert system by comparing real-time data feeds with established performance profiles for up to 10 VMs running on an ESX host supporting virtualized servers or virtual desktops. Its memory-based architecture allows Xangati to compare this data and identify any performance shifts live and continuously – not through intermittent polling intervals – giving managers unparalleled insights for faster troubleshooting. These insights, in turn, provide confidence for the migration of mission-critical applications in the VI and ensure end user satisfaction – the biggest factor in determining the success of VDI initiatives.

Xangati for ESX still includes all of Xangati’s trademark features, including: continuous scroll-bar and drill-down user interface (UI) capabilities for dynamic and real-time navigation; visibility into more than 100 metrics on an ESX/ESXi host and its VMs activity; and automated DVR recordings (triggered by VMware alerts) to capture critical events for replay analysis for precision troubleshooting as opposed to sifting through unstructured log files. Xangati for ESX is also deployed in Open Virtualization Format (OVF) to facilitate a faster and easier installation process. Xangati is committed to continue to incorporate capabilities that add value and help accelerate virtualization initiatives.

Available immediately, the updated Xangati for ESX works with VMware 3.5, 4.0 and 4.1 for ESX and ESXi. Xangati has also created an updated installation video and documentation for additional background about the new features in order to enable virtualization managers to begin using and benefiting from the free tool as quickly as possible. To access the installation video and download a copy of the free Xangati for ESX, go to http://xangati.com/xangati-for-esx-new-features/.
