Unified Storage is the way to move forward for Enterprise IT

Posted on January 21st, 2011 in Data Center, Hardware, Storage, Virtualization | No Comments »

Unified Storage………Sounds new to you? or sounds familiar to you? No right or wrong answer here, but it had become the dream of every storage vendor to offer this to their client especially in mid range, enterprise and virtualization environment. I remembered Netapp was the 1st started this, follow by other competitors in the market.

What is unified storage?

A single platform support multi-protocol such as FC, ISCSI, NFS, CIFS, FCoE and etc. It also support file, volume and block level data access.

You will able to get the unified box from either Netapp, EMC and HDS in the market now.

Does VMware vCenter Storage Plugin Really Matter?

Posted on November 3rd, 2010 in Storage, vCenter | 5 Comments »

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

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.

Reduce numbers of Server Racks in Data Center

Posted on June 13th, 2009 in Data Center, Hardware, Industry News, Virtualization, vSphere | No Comments »

With my last 3 years of experience, I had seen numbers of companies require significant expansion in the data center to support the business growth, just because of the additional 200 to 2000 servers or storage shelves they need to put in to the data center. With the technology today, it does help us to reduce the space we need to slot in the servers, and storage thanks to the success of virtualization and higher capacity disk drives in the market. To run a full solution of data center with less number of server racks for SME and enterprise, will no longer be a dream due to some facts below,

  1. Higher consolidation ratio in virtualization with the latest CPU, memory and servers performance
  2. Higher capacity disk drive which significant reduce the number of storage expansion require
  3. Virtual I/O which allow the higher utilization of the available bandwidth in data center
  4. UCS to provide consolidation and higher capacity of bandwidth to support network and storage utilization in the data center

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
