Storage De-duplication

Posted on October 20th, 2010 in Data Center, Hardware, Storage, Virtualization | No Comments »

Storage de-duplication is not a new term in the IT industry. It had been a while since few years back. Many users are confused with this term. Same goes to the Cloud Computing.  Every Storage vendor will claim they have the de-duplication solution today, but they are different from each others as we know.

General de-duplication solution:

  1. Primary SAN de-duplication
  2. Appliance target base de-duplication
  3. Host base de-duplication
  4. Software base de-duplication

I may had missed out some of them, but these should cover majority of the de-deduplication solution in the market today.

Storage vMotion with VAAI on EMC

Posted on August 16th, 2010 in Storage, Tips, vCenter, Virtualization, vSphere | No Comments »

In 1 of the demo video, I had seen the storage vMotion performance significant improve as much as 25% of the time and reduce the storage processor overhead at roughly 20% which offload the ESX performance during the storage vMotion execution. Previously, you may aware that the storage vMotion will usually take a long time and consume a lot of resource from Host & Storage. With vStorage API Array Integration, you will able to offload this to the storage array to handle directly which reduce the system overhead from ESX host itself.

Here is the option to turn on or off the VAAI, Value of Zero meant off, and 1 refer to ON.

VSI Plug-in for vCenter with EMC storage

Posted on August 11th, 2010 in Storage, Tips, vSphere | 1 Comment »

The new VSI plugin from EMC allow VMware administrator to self service, manage and provide transparency and visibility about the back end SAN storage in the vSphere infrastructure. This had transformed the traditional way how the VMware administrator manage and operate the virtual infrastructure in the past. All of us may agreed that the SAN configuration details are not visible to us previously due to lack of visibility in the management console. If you would like to verify something on the SAN, you may require assistant from the SAN admin, due to restricted access to the SAN box. Now with the new VSI plug-in, it will able to provide the necessary configuration information to the VMware administrator without having to engage the SAN admin to verify some minor information. The VSI plugin support all platform for EMC product range include Clariion, Celerra and Symmetrix.


Here show the plug-in which integrated the the vi-client directly

VMware acquire RTO Software and Ionix

Posted on February 26th, 2010 in Industry News, Virtualization | No Comments »

Within a week, there are 2 major accquires been done by VMware. By accquire RTO is not surprise to most of us as VMware trying to move forward with the complete cloud solution provider. But this morning, I got the sms from my buddy in VMware inform me about the accquire for Ionix and I am surprised.  After I read through the news this morning, here is the finidng. VMware did not 100% purchase Ionix from it parents company but some of it. Well, to me VMware and Ionix are both owned by EMC. Will there be any different whether is owned by VMware or EMC on this? We will have to keep an eye on that.

Unified Computing System with Unified Storage

Posted on January 30th, 2010 in Data Center, Server, Storage | 1 Comment »

Unified had become a key word today, and what does it really meant for everyone? It is similar as the phenomenal Cloud Computing 2 years ago.  We had seen the storage vendor are moving from FC SAN, ISCSI SAN, NAS to a unified storage today. What a unified storage does today are providing all the storage protocol standard in the market in a single box. Vendor such as EMC and Netapp had their Unified storage to support this today and proven to be performing and user are happy with it.

Beside unified storage, we are looking forward for unified computing system for the server compute platform too. Cisco had moved ahead of their competitor to bring this to the world and it is 1 fo the great platform that get attraction and adoption worldwide. Cisco UCS or Nexus 5000 both provide the unified I/O capabilities and allow us to transform the data center architecture today. Beside consolidating LAN and SAN into 1 with FCoE, the more interesting capabilities that get attention by us are the switching capacity.
