Loading Up on Virtual Servers

I visited a customer last week who was trying to run four 6 node ESX clusters with 200 to 240 instances per cluster on a large modular storage system. It was not surprising that the modular storage system could not support that workload. That type of workload needs to be run on a monolithic storage array [...]
Switch IT On II

In April I wrote about our “Switch IT On” program, which provides free software licenses to help current and new USP V customers leverage virtualization across their existing HDS and third party storage assets.

My post was intended to point out that while dedupe was an excellent tool for reducing storage bloat, it was [...]
I Agree with Chuck on Data Dedupe

Chuck Hollis had an interesting observation on deduplication of primary data and I/O density. He points out that while deduplication is great for backup, archive, and large file repositories, it might not be as great for primary data. His reasoning is that dedupe can cause an increase in I/O density which may impact the performance [...]
