I receive a lot of communication from recruiters, some of which I’m allowed to share, so I’ve decided to try something.  On the Jobs page, I’ll pass along virtualization and cloud centric opportunities – mostly US based but in some cases throughout the globe.  Only recruiter requests will be posted.  I won’t syndicate content easily found on the various job boards.  If you’re currently on the bench or looking for a new challenge, you may find it here.  Don’t tell them Jason sent you.  I receive no financial gain or benefit otherwise but I thought I could do something with these opportunities other than deleting them.  Best of luck in your search.

StarWind Releases iSCSI SAN Software Enhanced by VM Backup Technology

January 17th, 2012

Press Release:

New StarWind iSCSI SAN v5.8 and Hyper Backup Plug-in are a New Level of Data Protection

SnagIt CaptureBurlington, MA – January 13, 2012StarWind Software Inc., an innovative provider of SAN software for iSCSI storage and VM Backup technology, today announced the release of new StarWind iSCSI SAN v5.8 and Hyper-V Backup Plug-in. The iSCSI SAN software is enhanced by the powerful VM Backup technology that is included as a plug-in.

Backup plug-in is built specifically for Hyper-V-based environments to provide fast backup and restore for Hyper-V virtual machines. The backup solution delivered by StarWind performs all operations on the Hyper-V host level thus it requires no backup agents to be installed on virtual machines (Agentless Architecture).

Hyper-V Backup Plug-in makes fast backups and allows quick, reliable restore of both virtual machines and individual files. It utilizes advanced technologies for maximum disk space saving (Global Deduplication). This backup tool is integrated with StarWind Centralized Management Console that enables managing backup and storage from a single window.

Additionally, a new version of HA plug-in is presented in StarWind iSCSI SAN v5.8 that allows use of raw basic images to create HA targets. A new replication engine based on own technology instead of MS iSCSI transport creates higher performance and reliability. This new engine permits use of multiple network interfaces for synchronization and heartbeat.

To simplify the replacement of equipment and recovery of fatal failures, StarWind Software has implemented the ability to change the partner node to any other StarWind server without any downtime and on the fly. Synchronization engine is improved, and this version allows both nodes to sync automatically even in the case of a full blackout of both servers.

“With the release of StarWind iSCSI SAN v5.8 our company is happy to provide our customers with highly available storage and fast backup software developed by the same vendor,” said Artem Berman, Chief Executive Officer of StarWind Software. “Now small and medium-sized companies have an opportunity to achieve higher performance and absolute data protection.”

HotLink Launches Latest Version of HotLink SuperVISOR for VMware

December 14th, 2011

I don’t publish the majority of the press releases which make their way to my inbox but I took a quick look at HotLink SuperVISOR for VMware and what it does is interesting.  Watch the video below (feel free to expand to full screen to see the detail) and see how this product is able to pull in various Type 1 hypervisors in a heterogeneous datacenter under the vCenter management umbrella.  By now you know VMware isn’t the only player in the hypervisor business.  VMware’s competitors have been making their presence known.  They remain persistent partly because of their gradual market penetration.  And I’ll be the first to admit that the other hypervisors out there are the right fit for some business use cases and requirements.  Also, multi vendor policies are not uncommon in large organizations.  Whatever the reason, deploying different makes and models of hypervisors in an environment is your business.  Managing them with ease is HotLink’s business.  Read on.

HotLink Launches Latest Version of HotLink SuperVISOR™ for VMware

Leading enterprises including McAfee and BMC Software adopt HotLink SuperVISOR to seamlessly manage mixed hypervisors inside VMware vCenter console

SnagIt CaptureSUNNYVALE, Calif. – December 15, 2011HotLink® Corporation, the market leader in transformation solutions for heterogeneous virtualization management, today announced the newest release of its flagship product, HotLink SuperVISOR™ for VMware. HotLink SuperVISOR is the first and only solution to enable VMware vCenter users to natively manage cross-platform virtual infrastructure spanning Citrix XenServer, Microsoft Hyper-V, and Red Hat Enterprise Linux (KVM). The latest release, HotLink SuperVISOR for VMware 1.2, adds new capabilities focused on enterprise robustness, scalability, configuration and management of multi-hypervisors and workloads.

With its latest release, HotLink customers benefit from an enhanced virtual integration platform that provides total control and performance visibility across all enterprise hypervisors, using the VMware vCenter management console they already have. The new features of HotLink SuperVISOR for VMware 1.2 include:

  • Enhanced Networking Configuration – Users can now provision and modify virtual switches and network adapters from VMware vCenter and associate these to any enterprise hypervisor —enabling users to manage heterogeneous virtual networking from a single interface.
  • Expanded Performance Monitoring – The latest release expands the heterogeneous performance statistics and alerts that are gathered and displayed inside the native VMware vCenter performance tab —allowing administrators to quickly identify issues across the mixed hypervisor environment.
  • Robust Configuration of Virtual Machine Settings – Only HotLink provides the ability to modify the configuration of virtual machine settings such as virtual CPUs and memory assignments natively inside vCenter and apply across all virtual platforms —ensuring the optimum VM configuration regardless of the hypervisor.

“Enterprise IT needs are rapidly evolving as an increasing number of VMware shops are deploying heterogeneous hypervisor environments. Administrators need a single management console that provides a comprehensive view and complete control of all enterprise workloads,” said Lynn LeBlanc, CEO and founder of HotLink. “The latest enhancements to HotLink SuperVISOR extend the VMware vCenter management infrastructure to provide sophisticated and robust management capabilities to Hyper-V, XenServer and KVM – unifying the management of all virtual workloads inside VMware vCenter.”

As virtual infrastructure deployments expand and mature, heterogeneity is being fueled by a combination of economics and maturing of hypervisor alternatives. The most recent Gartner Magic Quadrant for x86 Server Virtualization Infrastructure report included, for the first time, both Citrix and Microsoft alongside VMware in the leaders quadrant. Moreover, Hyper-V grew 62 percent last year compared to ESX’s 21 percent growth and Citrix’s 25 percent, according to IDC. While the proliferation of multiple virtual platforms is accelerating, streamlined infrastructure is needed to unify management. That’s exactly what the latest release of HotLink SuperVISOR for VMware addresses.

“McAfee historically was an all VMware shop, but our business needs have changed so that we now have a mix of vSphere, Hyper-V and XenServer.  Utilizing HotLink SuperVISOR for VMware across our virtual environment enables us to increase our usage of other hypervisor platforms while unifying management. By deploying multiple hypervisors and standardizing on VMware vCenter as our primary management interface, we expect to reduce our virtualization cost by over 50 percent and admin costs by 65 percent over the next 3 years,” said Mark Tonnesen, CIO of McAfee. “The foundation of our multi-hypervisor environment is built on the HotLink SuperVISOR platform.”

With the new HotLink SuperVISOR technology, enterprises can tier their virtual infrastructure with cost-effective hypervisors and still unify the management, significantly reducing their licensing and operating costs. With HotLink SuperVISOR, customers can realize the benefits of mixed hypervisors while avoiding overly complicated management systems.

“Like many other IT shops, we are investigating the use of multiple hypervisors to cost effectively support development and test activities for our Tier 2 and Tier 3 business applications. We have been very impressed by HotLink’s SuperVISOR technology and the hypervisor interoperability that it enables.  We believe that HotLink will enable us to optimize the use of specific hypervisors for individual workloads without compromising our ability to manage our overall virtual environment,” said Mark Settle, CIO of BMC Software.

Pricing and Availability

HotLink SuperVISOR for VMware 1.2 is available now with pricing starting at $25,000. For more information, contact sales@hotlink.com or visit www.hotlink.com.

Tolly Group releases another Citrix vs. VMware comparison

April 15th, 2009

A few months ago, The Tolly Group released a report comparing Citrix and VMware VDI solutions.

They’re at it again. Today, The Tolly Group released another comparison. Today’s report compares Citrix XenServer 5 and VMware ESX 3.5.0 Update 3 with Citrix XenApp as the workload.

Citrix Systems commissioned Tolly to evaluate the performance of Citrix XenApp when running on Citrix XenServer 5 and compare that with XenApp running on VMware ESX 3.5u3.

Testing focused on system scalability and user quality-of-experience. This test report was approved for publication by VMware. The VMware End User License Agreement (EULA) requires such approval.

The testing was conducted in accordance with Tolly Common RFP #1101, Virtual Server Performance.

Summary of Results:

* Citrix XenServer 5 outperforms VMware ESX 3.5 by 41% in user scalability tests.
* XenApp, running on XenServer, retains a consistent user experience as load is increased to 164 users.
* Virtualizing 32-bit XenApp gives IT administrators a viable approach to increasing total user density on physical servers, without the need to re-certify their existing applications and drivers for a 64-bit platform.
* Consolidating XenApp farms on XenServer results in data center reliability benefits and cost savings.

Say it isn’t so: Hyper-V and XenServer outperform ESX

March 7th, 2009

This isn’t exactly the type of news I like to report but at the same time it can’t be ignored. The February/March 2009 issue of Virtualization Review magazine has an article starting on page 12 where Rick Vanover puts Hyper-V, XenServer, and ESX head to head to head. Some of the conclusions drawn are startling:

“For the first two tests of heavy workloads, VMware underperformed both XenServer and Hyper-V. For the lighter workloads on the third test, the results were almost indistinguishable across the platforms, but ESX had the best results in three of the four categories.”

“After doing these comparisons of ESX to Hyper-V and XenServer, it’s clear that at the hypervisor level, ESX is optimized for a large number of less-intensive workload VMs. For intensive workloads that may not be optimized for memory overcommit apps, Hyper-V and XenServer should definitely be considered-even if that means adding another hypervisor into the data center.”

Rick is saying that both Hyper-V and XenServer deliver better performance for the heavy workloads. ESX is better suited for lighter workloads and actually will handle more of them than Microsoft and Citrix making it the better “scale up” solution. Rick also points out that ESX offers the clear advantage of memory over commit which could not be benchmarked against Hyper-V and XenServer due to memory over commit not being available in the latter two products. For a moment, let’s assume that Rick’s findings are 100% accurate. From an options standpoint, how do you feel about scaling up versus scaling out for the lighter workloads having equal performance across all three platforms? Personally, I’d lean towards higher consolidation ratios, less capital expenditures, less datacenter and utility bill consumption. That’s the ESX option.

I’m concerned that I’m hearing ESX is underperforming against the underdogs. I’m not at all saying Rick’s tests are invalid but I am looking for a response from VMware that is either published, or in the form of ESX4 taking an obvious performance lead once again in benchmark tests. Charging a premium for a lesser performing hypervisor doesn’t sound like the right formula for success.

Update: Slight goof on the title of this blog post. Originally it stated “XenApp” where I meant “XenServer”

Update: Microsoft and VMware have responded to the original article’s performance analysis.

Virtualization Manager Mobile (VMM) beta 1 released

January 16th, 2009

Lostcreations, an Austin-based software company which specializes in .NET and Java solutions for the heterogeneous virtualization sector of IT, has released beta version 1 of a product they are calling Virtualization Manager Mobile (VMM).

While the product is new, the concept is not:  Remote monitoring and management of your datacenter when you’re at the beach (or wherever remote management is inconvenient using traditional tools like laptops and WiFi).  It’s done through a hand held device having a web browser.

Beta 1 has the ability to monitor virtual machine CPU and memory utilization, as well as stop, start, suspend, and reset the VM.  The product currently supports VI3, and VMware Server 2.  Expect many new features in future versions including support for Hyper-V and XenServer 5 as well as the ability to develop your own plug-ins to extend other hypervisors.

The technology behind the tool includes AJAX and the Google Web Toolkit and the application back end installs on Windows, Linux, and OS X.  Lostcreations even provides a live demo to see the tool in action first hand!

After a decade of talking about it, we’re finally getting there!

Confused about Citrix XenServer 5 support for Windows Server 2008

November 25th, 2008

I read a news item here stating Citrix XenServer 5 lacks support for Windows Server 2008 as a guest operating system. I decided to check it out for myself.

Citrix reveals here that indeed Windows Server 2008 guests are not supported in XenServer 5. However, the What’s new in Citrix XenServer 5 page explains that XenServer 5 is tuned for Windows and Windows Server 2008 guest support has been added through the all important Microsoft Server Virtualization Validation Program (SVVP).

Confused? I am.

VMware supports Windows Server 2008 for many of its products and VMware is very clear about it. VMware’s guest OS support for all VMware products can be found in the Guest Operating System Installation Guide.
