StarWind/Mellanox Add Datacenter Storage Efficiency

May 7th, 2011

Press Release:

StarWind iSCSI SAN software coupled with Mellanox Ethernet-based high speed end-to-end infrastructure accelerates storage networking connectivity and lowers overall power consumption

StarWind SAN iSCSI software running over a Mellanox ConnectX®-2 40GE networking solution provides better performance, high availability (HA) and redundant iSCSI storage solutions at 40Gb/s bandwidth and high IOPS.

Burlington, Mass. – April 27, 2011StarWind Software, a global leader and a pioneer in SAN software for building iSCSI storage servers, today announced that StarWind SAN iSCSI software has achieved a record level of 27 Gb/s throughput and 350K IOPs running over a Mellanox ConnectX®-2 40GE networking solution.

StarWind has recently conducted the test under Mellanox Enterprise Datacenter’s initiative where the following testing configuration has been used: 3 servers of Zorro (HP DL380 G6 with 2*167GB disks, 24GB RAM, 8 cores); 6 Mellanox HCAs with 40Gb/s single port, 2 HCAs in each server; connected with 3 subnets, copper QSFP cables; OS: Windows 2008 Server R2.

Testing showed StarWind software has achieved record connectivity performance:

  • With the non-HA configuration (one node of the HA cluster and the client were performing I/O through the single 40Gb/s connection in both directions utilizing full-duplex Ethernet connection) the cluster got 25Gb/s of an iSCSI traffic (due to PCIe Gen 2 system limitations full 40Gb/s wire speed has not been reached). More than 300K IOPs at 25Gb/s have been achieved with 16 clients using StarWind iSCSI SAN software.
  • The full HA (two nodes: HA 1 and HA 2 processed requests served under Round-Robin) has achieved the same results as the non-HA configuration, but with more workers and deeper I/O queue.

In the near future 40Gb NIC will provide four times higher performance compared to 10Gb NIC for the same price.

“We thank Mellanox Technologies for helping StarWind iSCSI SAN software to continue setting new performance records. Just one year ago StarWind was used in the iSCSI performance tests by Microsoft and Intel, achieving a groundbreaking one million I/Os per second,” said StarWind’s CEO Artem Berman. “StarWind Technology Alliance Program builds relationships with best of breed technology companies to align technology, create leading solutions and help customers adopt our collective products.”

For more information on the test and performance benefits using StarWind iSCSI SAN software version 5.6 with Mellanox ConnectX-2 EN Adapters plus 10Gb/s or higher speeds (preferably 40Gb/s), for current and future x86 servers along with PCIe Gen2 and PCIe Gen 3-enabled systems, visit:

VMTurbo Free Performance and Efficiency Reporter

May 4th, 2011

Press Release:

VMTurbo Announces Availability of Free Performance and Efficiency Reporter

Reporting joins Monitoring application as a complimentary, useful productivity tool that provides valuable insight into virtual environments

Valhalla, NY, May 4, 2011 — VMTurbo, provider of software to analyze, optimize and control the virtualized data center, today announced free, immediate availability of VMTurbo Performance and Efficiency Reporter. Available for download at the VMTurbo site, VMTurbo Performance and Efficiency Reporter joins VMTurbo Monitoring as a complimentary, useful productivity tool that provides valuable insight into the virtual environment.

With its breakthrough real time workload management algorithm, VMTurbo assures the performance of the applications running in the virtualized environment while utilizing the underline infrastructure as efficiently as possible. VMTurbo “ties the viewing with the doing” by proactively providing corrective actions for any potential performance bottleneck as well as workload placement and configuration actions to maximize resources utilization. Furthermore, leveraging the same algorithm for planning, VMTurbo maximizes the ROI from the virtualized environment in real time and all the time.

“The real value of VMTurbo is its ability to automate and optimize the virtual environment in real time, so it makes sense to give away both our monitoring dashboard and performance reports, which are really just table setters for IT management,” said Shmuel Kliger, president and CEO, VMTurbo. “Now any organization can experience the benefits of VMTurbo in their own data center without having to spend a single dollar.”

The VMTurbo Performance and Efficiency Reporter package is a collection of reports that fall into two categories.

Performance Reports

  • Host/VM Utilization Heat Map contains an ordered ranking of utilization (UI) for both physical hosts as well as virtual machines. Raw data for each host and each VM also is provided. Useful metrics include the peak utilization. This data enables both an “at-a-glance” indicator of workload as well as useful information for provisioning.
  • Host Top CPU Ready Queue provides a detailed breakdown of the metric surrounding CPU ready states. By showing both the host total wait times (aggregated over a sample period) and the total times waited by virtual machines for each multiple of vCPUs, the report provides insights into how either a re-allocation of vCPUs or the re-location of a VM would impact this raw performance metric.
  • Storage Access IOPS delivers a raw ranked standing of data stores in the environment. By aggregating and displaying the raw average sustained IOPs to and from these datastores, users can evaluate the suitability of the datastore against the applied workload and potentially make a better allocation. Further, by looking at the total storage used (vs. capacity), users are better able to plan for anticipated growth.

Efficiency Reports

  • VM Over/Under Provisioning looks at the resources consumed (taking into account historical peaks) to make meaningful recommendations as to right-provisioning. This potentially frees up additional resources that could be re-allocated to improve performance or accommodate additional VMs.
  • Storage Wasted Allocations provides immediate visibility into data stored on the managed drives that is not associated with any VM. With this ranked data, users can quickly free up potentially vast amounts of unused storage at a considerable cost saving.
  • Storage Allocated to Dormant VMs both identifies dormant VMs and enables the reclamation of their disc space. This can yield significant cost savings through resource reclamation and the ability to subsequently host additional VMs on the same hardware.
  • VM Rightsizing Recommendation is based on configurable thresholds as well as analyses of specific time ranges for each VM to make intelligent configuration recommendations based on the actual resource demands of the VM. This ability to intelligently right size represents a significant efficiency improvement over other more wasteful allocation strategies.

Test Drive the VMware View App for iPad

May 1st, 2011

Nearly two months ago, the VMware View app was released by VMware for the iPad and I wrote about it here.  Since then, many in the community have been curious as to what the end user computing experience was like.  They have iPads and of course they have free access to the View app but they lacked a VMware View environment to connect to, particularly a remote over-the-internet scenario using View 4.6 5.0 5.0.1 GA and PCoIP.

Early on I worked with a few individuals on a 1 on 1 basis, providing access to a test VDI desktop intance in my lab.  They tested for up to a week and demoed for upper management in the company.  When testing was complete, they went on their way.  After a few iterations, I decided that there was some value in what I was doing, but the continuous setup and retirement of accounts isn’t something I wanted to continually track.  As a result, I’ve set up a persistent VDI instance in my View 4.6 5.0 GA lab which can be accessed any time using generic credentials from your iPad by following these steps:

How to connect:

Step 1) Grab yourself an iPad if you don’t already have one (1st or 2nd generation both work).

Step 2) Connect your iPad to the internet.  Be sure TCP/UPD 4172 ports are not blocked.

Step 3) Get yourself the VMware View for iPad app:

SnagIt Capture

Step 4) Provide the following connection specifications in the VMware View for iPad app:

Snagit Capture


Step 5) If you’re prompted for credentials at Windows 7 logon, use the credentials shown above.

Step 6) Enjoy but do try to limit the duration of your connectivity.


The Windows 7 test VM provides basic desktop application access.  Bandwidth from the VDI lab standpoint is 16Mpbs down, 2Mbps up.  On your end, that’s 2 down, 16 up.  It is the internet; performance and speeds will vary.  By design, one user session is allowed at a time.  There is only one desktop instance.  The idea is to use the session for a few minutes to get a feel for the client experience.  The session is not for long term or production use.  No warranties, use at your own risk, etc.  In reality, the longer you maintain connectivity, the more chance you have of being interrupted by another user requesting to use the desktop.  If you’re trying to log on and you receive a message stating “The View agent reports that this desktop is currently logging off a previous session.”, you are probably interrupting someone elses session.  Try again later.  If you are currently in a session and it abruptly ends, it is likely the result of someone else submitting a logon request – sorry – At this point I do not know how to prevent the session interruptions which is essentially a “following” feature which would commonly be used in a health clinic.  If you have any ideas, please share in the comments section below.

To maintain a safe environment, web browsing and access to some other areas of the OS has been disabled.  All activity is logged.  The VM will reset at regular intervals in an effort to restore back to its original clean starting point.

Updated 9/18/11:  The environment has been upgraded to View 5.0 GA

Updated 11/6/11:  Thanks to the notification of a few friendly folks, I found out the environment was no longer functional. In short, the computer password for the VDI workstation was out of sync.  I’ve fixed this an enhanced the environment for longer term use which should prevent future implosions.  The demo environment now supports two concurrent demo sessions using the same credentials. In addition, each demo session is deleted upon a disconnection and a new VDI workstation is built.  This is all done by the addition of VMware View Composer to the environment.

Updated 3/28/12:  The environment has been upgraded to View 5.0.1 GA
