Umem NVRAM Cards
Umem™ cards are battery-backed RAM cards that replace disk accesses with non-volatile memory accesses to improve response time and maintain reliability in server and storage appliances.
The original Umem cards were designed for Prestoserve™, the ubiquitous host write-caching software module OEM’d by companies such as Hewlett Packard, IBM, and Sun Microsystems.
Especially applicable to file servers and storage appliances that adhere to the NFS protocol or utilize journaling filesystems, Umem cards enable these products to improve performance for I/O intensive applications and still comply with the industry standard benchmark, SPEC SFS.
