HP XP P9000 Cache LUN (also known as Cache Residency)
Overview HP XP P9000 Cache LUN lets you reserve areas of memory cache on your HP XP
P9500 Storageto store frequently accessed information. It improves file access times and enables
faster data transfers.
Assigning information to on-board cache speeds up access to your data because cache-resident
data isavailable at host data transfer speeds for both read and write operations. XP P9000 Cache
LUN redirects I/Orequests from the XP P9500 drives to data locked in the array’s cache. It is
transparent, it is simple toimplement, and the performance gains it delivers are immediate.
