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.”

Path Set for Dell Storage Forum 2012 London

January 11th, 2012

Snagit Capture

In just a few days, Dell Storage Forum 2012 kicks off at the Grange St Paul’s Hotel in London. I will be in attendance and I hope that you will have the chance to join myself and the rest of the Dell staff and of course an array of storage customers, channel partners, enthusiasts, and analysts. At DSF your appetite will be satisfied with Executive lead Keynote sessions, Breakout sessions delivered by Technical Experts, Instructor lead training, and Hands-on/Self-Paced labs covering Compellent Storage Center, Dell EqualLogic, and PowerVault storage.

This venue won’t be an exact carbon copy of past DSF events. Dell Storage will be showcasing an updated product roadmap and we’ll also see new product announcements. One of the announcements you’ll hear about is the availability of Compellent Storage Center 6.0. As a Technical Marketing Product Specialist who spends all time working on the VMware integration points, this is a release I’ve been looking forward to since starting my career at Dell Compellent in May of last year. This is a significant launch for Dell Compellent from an architectural perspective. SC 6.0 now leverages the FreeBSD 64-bit platform. The 64-bit architecture is the springboard for new features launched this week (such as multithreading opportunities and 12GB memory per Series 40 controller) and will serve as a key enabler for future scalability, integration, and feature enhancements.

If you’re a current Dell Compellent customer with vSphere 4.1 or newer in your datacenter, you know that through SC 5.5.x we supported one VAAI primitive: Zero Blocks or Write Same. Storage Center 6.0 supports additional VMware vSphere VAAI primitives:

  • Copy Offload
  • Hardware Assisted Locking
  • Of course we still support Block Zeroing

On a side note, VMware also released a 4th VAAI primitive in vSphere 5 focusing on Thin Provisioning for block storage arrays.  However, shortly after the release, VMware pulled support on this primitive (applies to all storage vendors) to work out some kinks.  I wrote about that here.

VAAI excites me because of the performance and scalability gains it brings to the vSphere virtual datacenter in addition to vSphere bolt ons such as VMware View and vCloud Director.

Compellent SC 6.0 VAAI support:

  • 41% faster block cloning operations on Eager Zeroed Thick and Lazy Zeroed Thick virtual disks
  • 98% faster Eager Zeroed Thick disk creation
  • Up to 100% reduction in Block Zeroing data traffic from host to storage
  • Offloaded operations result in significantly reduced copy traffic between host and storage
  • Offloaded operations result in reduction of ESX(i) host resource and storage fabric utilization

Find more details about VAAI at VMware KB 1021976 vStorage APIs for Array Integration FAQ.

This should be a really great week.  Personally, it will be my first Dell Compellent focused conference.  I do hope to see you there and look forward to some good discussions.  If you’re not able to attend in person, you can use these links to follow the action remotely:

VCA4-DT and VCP5 Exam Reviews

January 6th, 2012

With 2011 wrapped up and the holiday festivities over with, I decided to kick off 2012 by sitting a few new VMware certification exams.  Before I get into the details of the exam experience, I must extend my sincere appreciation to the new testing center I tried out – New Horizons Computer Learning Center in Eagan, MN.  It’s a new facility, friendly staff, state of the art equipment, AND THEY ALLOW COFFEE IN THE EXAM ROOM!  I’m locked on to this facility for all future exams.

Ok, VMware Certified Associate 4 – Desktop, otherwise known as VCA4-DT.  Thursday morning, 70 questions, multiple choice, 90 minutes if I remember right. Time isn’t much of a factor on this exam as it has been in past exams I’ve sat.  Unfortunately I failed by a narrow margin. 289/500 (300 is the passing mark).  Not passing was a bummer since I’ve only failed one other exam and that was 14 years ago.  The reality was that I hadn’t had enough View Administrator seat time to recall what was being tested.  I can’t go into specifics but I will say that having a photographic memory of the View Admin console will go a long way to get by this exam.  I’ve managed a tiny View 4.6 and now 5.0 environment in my lab but I haven’t spent countless hours in the console on a day to day basis which is what I think is really required.  That makes sense – after all it is an Administrator role based exam.  My hope was that brushing up on the blueprint objectives and reading Mike Laverick’s Administrating VMware View 4.5 book cover to cover the night before the exam would have been enough to get by.  It wasn’t.  No fault to Mike of course, his was a fine book.  I planned short on the preparation, rolled the dice, and.. well you know by now what happened.  It was a humbling experience but at the same time it’s an effective method to learn more.  After I get back from Dell Storage Forum London I’ll plan on hitting the lab and ultimately finishing the exam the proper way.  After that, I’ve got my sights set on VMware Certified Professional 4 – Desktop (VCP4-DT) which I may already be better prepared for.

On to the VMware Certified Professional 5 or VPC5.  Friday morning, 85 questions, multiple choice, 90 minutes.  I reached the end of the exam with 14 minutes left to review marked questions – I had quite a few.  I don’t know why – I rarely change my answer when reviewing questions.  I mark the questions with the intent that there may be a better answer which comes to me later on in the exam but it rarely happens and I believe statistics prove that on average, first instinct is going to be the better or correct answer.  I’ll be honest, dwelling on yesterday’s fail did a number to my confidence level but I had no choice but to push forward studying the blueprint for a solid 8 hours last night into the wee hours of the morning.  Granted, the VCP5 exam should be higher on the difficulty level, but the infrastructure content maps quite a bit better to my expertise that VMware View administration does.  I had seen some comments from others that the VCP5 exam didn’t contain much along the lines of Configuration Maximums type questions.  Based on that, I didn’t spend much time in the vSphere 5 Configuration Maximums document.  I brushed up on HA, DRS, and although I have little hands on working experience with the appliance based bolt ons like the vCenter appliance, vDR, VSA, or Auto Deploy, I tried to pick up as much as I could on those areas.  On exam difficulty, the content came easier to me based on familiarity.  For most of the exam I was pretty well within my comfort zone.  As a Technical Marketing Product Specialist at Dell Compellent, the storage related questions aren’t quite the level of difficulty they once were.  There was a pretty good blend of easy/medium/difficult questions, and also a few which I felt were worded poorly enough such that I knew the correct answer either way, but interpretation of the question is going to determine a right or wrong answer.  Results on this exam were better – 406/500 (300 passing).  There were plenty of questions on the other vSphere products I talked about earlier such as the vCenter appliance, vDR, VSA, and Auto Deploy. While I feel I did answer a few of those questions correctly, the remainder is likely what accounts for the majority of the points I missed on the exam.  By the way, if you’re not using vSphere Update Manager on a regular basis to assist in upgrading your environment, you should be, and you’ll want to know that product for this exam as well.

Have a great weekend and for those attending Dell Storage Forum London next week, I hope to meet up with you.

vCloud Director and vCenter Proxy Service Failure

December 16th, 2011

In the past couple of weeks I have spent some time with VMware vCloud Director 1.5.  The experience yielded three blog articles Collecting diagnostic information for VMware vCloud Director, Expanding vCloud Director Transfer Server Storage and now this one.

In this round, the vCD cell stopped working properly (single cell server environment).  I could log into the vCD provider and organization portals but the deployment of vApps would run for an abnormally long time and then fail after 20 minutes with one of the resulting failure messages being Failed to receive status for task.

Doing some digging in the environment I found a few problems.

Problem #1:  None of the cells have a vCenter proxy service running on the cell server.

Problem #2:  Performing a Reconnect on the vCenter Server object resulted in Error performing operation and Unable to find the cell running this listener.

I search the Community Forums, talked with Chris Colotti (read his blog) for a bit, and then opened an SR with VMware support.  VMware sent me a procedure along with a script to run on the Microsoft SQL Server:

  1. BACKUP the entire SQL Database.
  2. Stop all cells. (service vmware-vcd stop)
  3. Run the attached reset_qrtz_tables_sql_database.sql
    — shutdown all cells before executing
    delete from qrtz_scheduler_state
    delete from qrtz_fired_triggers
    delete from qrtz_paused_trigger_grps
    delete from qrtz_calendars
    delete from qrtz_trigger_listeners
    delete from qrtz_blob_triggers
    delete from qrtz_cron_triggers
    delete from qrtz_simple_triggers
    delete from qrtz_triggers
    delete from qrtz_job_listeners
    delete from qrtz_job_details
    go
  4. Start one cell and verify if issue is resolved. (service vmware-vcd start)
  5. Start the remaining cells.

Before running the script I knew I had to make a few modifications to select the vCloud database first.

When running the script, it failed due to case sensitivity with respect to the table names.  Upon installation, vCD creates all tables with upper case names.  When the MS SQL Server database was first created by yours truly, case sensitivity, along with accent sensitivity, were enabled with COLLATE Latin1_General_CS_AS which comes straight from page 17 of the vCloud Director Installation and Configuration Guide.

After fixing the script, it looked like this:

USE [vcloud]
GO

— shutdown all cells before executing
delete from QRTZ_SCHEDULER_STATE
delete from QRTZ_FIRED_TRIGGERS
delete from QRTZ_PAUSED_TRIGGER_GRPS
delete from QRTZ_CALENDARS
delete from QRTZ_TRIGGER_LISTENERS
delete from QRTZ_BLOB_TRIGGERS
delete from QRTZ_CRON_TRIGGERS
delete from QRTZ_SIMPLE_TRIGGERS
delete from QRTZ_TRIGGERS
delete from QRTZ_JOB_LISTENERS
delete from QRTZ_JOB_DETAILS
go

The script ran successfully wiping out all rows in each of the named tables.  A little sidebar discussion here.. I talked with @sqlchicken (Jorge Segarra, read his blog here) about the delete from statements in the script. It is sometimes a best practice to use the truncate table statement instead so that the transaction logs are bypassed instead of using the delete from statement which is more resource intensive due to the row by row deletion method and the rows being recorded in the transaction logs. Thank you for that insight Jorge! More on MS SQL Delete vs Truncate here. Jorge was also kind enough to provide a link on the subject matter but credentials will be required to view the content.

I was now able to restart the vCD cell and my problems were gone. Everything was working again. All errors have vanished.  I thanked the VMware support staff and then tried to gain a little bit more information about how the problem was resolved by deleting table rows and what exactly are the qrtz tables?  I had looked at the table rows myself before they were deleted and the information in there didn’t make a lot of sense to me (but that doesn’t necessarily classify it as transient data).  This is what he had to say:

These [vCenter Proxy Service] issues are usually caused by a disconnect from the database, causing the tables to become stale. vCD constantly needs the ability to write to the database and when it cannot, the cell ends up in a state that is similar to the one that you have seen.

The qrtz tables contain information that controls the coordinator service, and lets it know when the coordinator to be dropped and restarted, for cell to cell fail over to another cell in multi cell enviroment.

When the tables are purged it forces the cell on start up to recheck its status and start the coordinator service. In your situation the cell, due to corrupt records in the table was not allowing this to happen.

So by clearing them forced the cell to recheck and to restart the coordinator.

Good information to know going forward. I’m going to keep this in my back pocket. Or on my blog as it were.  Have a great weekend!

VMworld 2011 Hands On Lab Posters

December 15th, 2011

If you were at VMworld 2011 US and/or Europe, you may have seen or heard of the posters being given away at the Hands On Labs.  Supplies were limited at the US conference and if you attended in Copenhagen maybe you didn’t get a chance to get into the labs to grab some posters.

Although VMworld is over, you still have access to the posters.

One way would be to request a Dell Compellent Executive Briefing with me. I brought a few pounds of posters back from Copenhagen and what’s mine is yours if you’re willing to listen to me talk about the great integration points Dell Compellent Storage Center has with VMware’s growing portfolio.

The other option would be to go online and grab a copy of the posters which you can view electronically or have printed at your local copier shop.  This blog post was inspired by Xtravirt email bulletin 94 – thanks for pulling together the links guys.
