Posted on August 23rd, 2009 in Virtualization | No Comments »

FCoE is new today for data center environment, but it will be very soon adopt by most of the users in 2 years time. If we look at the current environment in most data center today, there will be isolated environment of FC connection for Storage and Ethernet connection for networking purpose in every single data center. Cabling management and knowledge require to keep the environment running and organize is becoming more challenging from time to time. Well, with the FCoE technology from Cisco, it will definitely simplify everything for us.

NFS ISCSI and FC Storage on vSphere

Posted on August 8th, 2009 in Storage, Virtualization, vSphere | 1 Comment »

NFS, ISCSI and FC storage are all supported in VMware vSphere today. As some of the benchmark been done recently showed the performance of ISCSI and NFS had been improved versus ESX version 3.5.  In the benchmark report it show that the overhead on NFS and ISCSI were higher VS FC storage. With the latest processors chip from Intel and AMD, I believe the overhead on the CPU will not be the major concern as users are always considering to maximize the usage of the CPU power they have in the physical server.

Performance tuning on Virtual Infrastructure with MD3000i

Posted on May 25th, 2009 in Server, Storage, Tips, Virtualization, vSphere | 10 Comments »

With the recent experience I had on the deployment with vSphere 4 and PowerVault MD3000i, I found there are plenty of room you may able to further fine tune to improve the performance of the storage and virtual infrastructure. Before this, the initial deployment was done by default configuration without any fine tune yet, and I found that the storage performance looks  little bit slow. Therefore, I had decided to further research and fine tune everything we had to improve the performance.

Equipment List

  1. 2 x R710 with Intel 5530
  2. 2 x PowerConnect 5424
  3. MD3000i with 15 SATA Disks
  4. Software ISCSI initiator from vSphere 4

There had been numbers of review and discussion regarding the choices of storage for us to run on Virtual Environment today. I believed that the hot discussion is always moving talk about the right storage with right design and implementation to the VM farm always. The most hottest topic are still regarding the NFS, ISCSI and FC implementation which provide better features, performance and reliability.

Personally, I had 3 of it running in my environment now and of course, I had spent a huge number of times to really test out all the solution and compare apple to apple to further study of my requirement. Here are some reading I get from my test for 3 solution above.

It could be support both 500GB and 1TB SATA II spindles up to 48 drives in a single array of 4U. A very impress usable storage space in single array which up to 48TB in raw. If we compare to the capacity, it is hardly found that a single array would provide a huge capacity at 48TB in Raw today. In additional to that, DELL had provide all the necessary features as for storage management as free which integrated as part of the storage purchase for Dell Equallogic ISCSI SAN. The latest features is regarding the Snapshot Manager for VMware. Previous version is only supported on Microsoft environment, but now, it had also supported on VMWare environment.
