Who is Compellent? May not be famous in our country, but it been 1 of the best SAN solution out there is Others region. They had also participate in the latest VMware vforum 2010 event through the local distributor this year in Kuala Lumpur. Since dell lost the bid to HP for taking over 3PAR Storage solution, many of us had predicted the next move DELL could target would be Compellent. Not a bad choice I will say as DELL do need visionary technology team who can drive the enterprise storage business for them in the long run.

I had gone through numbers of interesting discussions with the users I met in the past which talk about the disaster recovery plan in their current and future environment. DR is not a new topic for every enterprise environment, but it is always important for the enterprise environment to have DR in place due to business critical and compliance purposes. While virtualization continue penetrate into enterprise environment by taking mission critical workload, Disaster Recovery solution become a must to be consider which may require users to redesign their DR solution.
Traditional legacy or standalone environment, we often realize there are many solutions perform replication from primary data center to DR center via host base, storage base or image base replication. All of them has the pros & cons depend what is the objective of the specified DR project users are looking at. DR consistency and usability during DR scenario & practices always the biggest challenge in every IT department today.

I have a discussion about VMware vCenter Storage Plugin during VMware Hitachi boot camp today.
As I know EMC have EMC Storage Viewer, EMC Celera SRM Failback Tool & EMC Celera SRM Failback Tool and NetApp have Rapid Cloning Utility (RCU), Virtual Storage Console (VSC), SnapManager® for Virtual Infrastructure & SANScreen® VMInsight vCenter Plugin. I’m not going to discuss about the vCenter plugin features here.
Does vSphere admin really need VMware vCenter Storage Plugin?

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:
- Primary SAN de-duplication
- Appliance target base de-duplication
- Host base de-duplication
- 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.

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.
