RAID Cache
After posting about how having lots of RAID cache has a positive impact on local disk VDI I thought it best to mash together a little guide on how to get this cache setup so here it is!
All screen shots are from a HP DL385 G7 server – other HP server models may have a different UI but the idea will be the same.
For the past few days I’ve been doing a little performance testing to see just how much an influence RAID cache makes when provisioning Virtual Desktops.
