Hello again folks, in the SMB world, especially during these economic times, we can’t always spend all the money we want on storage. Generally customers are limited to looking at some pretty low end storage options.
I have always been a proponent of usings Blades in the SMB along with virtualization to reduce costs for the SMB. But what do you do for storage? Well the most common thing people look at is iSCSI vs FC. Usually people end up going the iSCSI route due to it’s lower cost factor.
Well another thing you can look at is direct attached storage. HP offers something called Direct Connect SAS storage for their HP BladeSystem. This can give you up to 420 TB of zoned or up to 192 TB of shared storage. This can be an attractive alternative for the SMB.
The way it works is by use of controllers installed in the blade severs along with blade switch interconnects and then finally either an MSA2000sa for shared storage or an MDS600 for direct attached storage. You can read more about the solution from HP here.
