VMware vExpert 2013 : Hurry UP !!!

After a long awaiting days…its now announced, if you think you want to be one of them….its there.




Today John Troyer (@jtroyer) – Social Media Chief and Community Evangelist @VMware opened the gates for a new round of vExpert Nominations. To apply you need to nominate yourself and describe all the hard work you have put into the VMware community last year. This itself is not that easy to do… try to remember what you  did last year…

vExperts who participate in the program have access to private betas, free licenses, early access briefings, exclusive events, free access to VMworld conference materials online, and other opportunities to interact with VMware product teams. They also get access to a private community and networking opportunities.

As with last year, there are three paths to being designated a vExpert. Each path takes into account the accomplishments and activities over the last year.

Evangelist Path
The Evangelist Path includes book authors, bloggers, tool builders, public speakers, VMTN contributors, and other IT professionals who share their knowledge and passion with others with the leverage of a personal public platform to reach many people. Employees of VMware can also apply via the Evangelist path. A VMware employee reference is recommended if your activities weren’t all in public or were in a language other than English.

Customer Path
The Customer Path is for leaders from VMware customer organizations. They have been internal champions in their organizations, or worked with VMware to build success stories, act as customer references, given public interviews, spoken at conferences, or were VMUG leaders. A VMware employee reference is recommended if your activities weren’t all in public.

VPN (VMware Partner Network) Path
The VPN Path is for employees of our partner companies who lead with passion and by example, who are committed to continuous learning through accreditations and certifications and to making their technical knowledge and expertise available to many. This can take shape of event participation, video, IP generation, as well as public speaking engagements. A VMware employee reference is required for VPN Path candidates.

So, If you think you did a lot of good work for the VMware community last year. Please apply for vExpert 2013:
The deadline for applications is April 15, 2013 at midnight PDT.

If you think someone should apply. You can recommend someone to apply for vExpert 2013:

Please note: You can apply without a recommendation, and extra points are not given for multiple recommendations, so please don’t lobby for multiple people to recommend you as “votes.”


VMware VMUG Qatar : Inaugural meeting & My experience

After a long awaiting months, after its launch, we are able to arrange the first official VMUG meeting in Doha, Qatar (on March 5, 2013) and it was a successful event. Follow us on Twitter @VMUGQatar

It was really an amazing experience to participate in this community event. We have launched this group on December 2012, Great thanks goes to Tom O’Reilly (Head of Server Systems at Maersk Oil Qatar) and Maqsood Siddiqui (VMware Employee) for their efforts to launch a VMware user group in Qatar for the first time. For HARD CORE FANS of VMware …it’s a relief.

The meeting was happened at Renaissance Hotel, City Center, Doha, Qatar. A warm welcome speech from our Qatar VMUG leader Tom, followed by a fantastic presentation of the latest VMware product Horizon Suite, delivered by Maqsood. The meeting was concluded by the presentation regarding VMware SRM by the Tom’s colleague Anoop.

As a steering committee member of the VMUG Qatar group, it’s makes me proud and happy.

Few snaps from the event !!!


Tom and Anoop BUSY in the preparations …..


Maqsood – Introducing VMware Horizon, it’s a cool presentation, he talked about VMware Mirage, its use cases.



Got a wonderful gift from the VMUG….for sweet memories !!!


Deduplication Internals – Source Side & Target Side Deduplication: Part-4

In Continuation of my deduplication series Part 1, Part 2, Part 3, in this part we will discuss where the deduplication happens. Based on where the dedupe process is happening, there is 2 types – That is Source Side or Client side and Target side. These are widely used in the Backup Technology, that is backup software and hardware appliances. Like IBM Tivoli TSM, Symantec backup Exec, EMC Avamar, Netbackup etc.

Source or Client Side Deduplication.

From the Name itself we can say, the entire deduplication is happening on the Client (Servers), there will be dedicated deduplication agents installed in the servers and these agents use the CPU/RAM of the server to perform the deduplication. This  thereby distributing the deduplication processing overhead across multiple systems.


Source-side deduplication typically uses a client-located deduplication engine that will check for duplicates against a centrally-located deduplication index, typically located on the backup server or media server. Only unique blocks will be transmitted to the disk. So less data to transfer so the backup window is also get reduced.

Source-based deduplication processes the data before it goes over the network. This reduces the amount of data that must be transmitted, which can be important in environments with constrained bandwidth. That is less network bandwidth needed for the backup software.

This method is often used in situations where remote offices must back up data to the primary data center. In this case, deduplication becomes the responsibility of the client server.

Target Side Deduplication.

Target-based deduplication requires that the target backup server or a dedicated Hardware target dedupe appliance handles all of the deduplication. This means no overhead on the client or server being backed up. This solution is transparent to existing workflows, so it creates minimal disruption. However, it requires more network resources because the original data, with all its redundancy, must go over the network.


So a target deduplication solution is a purpose built appliance, so the hardware and software stack are tuned to deliver optimal performance, so there is no additional CPU/RAM resource usage in the client servers.

Dell DR4000, Symantec NetBackup PureDisk, Symantec NetBackup 5220, EMC Avamar, HP StoreOnce, EMC’s Data Domain, ExaGrid Systems’ DeltaZone and NEC’s Hydrastor, IBM’s ProtecTier and Sepaton’s DeltaStor, Quantum DXi are the main examples which uses this type of deduplication.

My next post will be about the Inline and Post processing deduplication………!! Stay Tuned !!!
