Tech Preview of EMC’s XtremIO Flash Storage Solution

There is no doubt that Flash is hot right now. Over the past number of months, we have seen IBM acquire Texas Memory Systems (TMS), HDS unveil their own flash strategy and HP launch their all flash 3PAR P1000 array. Of course regular readers of my blog will have seen my posts about newer all flash array vendors such as Pure Storage, Violin Memory & Nimbus Data. The purpose of this post is to highlight XtremIO’s flash storage solution which was recently acquired by EMC.

vCloud Director 5.1 & Storage DRS

Another feature which was introduced in vSphere 5.1 & vCloud Director 5.1 was the interoperability between vCloud Director & Storage DRS. Now vCloud Director can use datastore clusters for the placements of vCloud vApps, and allow Storage DRS do what it does best – choose the best datastore in the datastore cluster for the initial placement of the vApp, and then load balance the capacity and performance of the datastores through the use of Storage vMotion.

VSA Cluster Service Considerations

Some changes have been made to the vSphere Storage Appliance (VSA) Cluster Service in version 5.1. Previously, the VSA Cluster Service was installed on the vCenter Server – there was no way to decouple it. However in VSA 5.1, the VSA Cluster Service is a stand-alone entity. It can still be deployed on the vCenter server, but it can also be deployed outside of it.
