RAID & HBA Controllers — Description

A RAID controller with write cache enabled gives the server speed, but a power loss without cache protection means lost data and a damaged array – the CacheVault module is what removes that risk. The category lists the LSI CVPM05 CacheVault module for the MegaRAID 9460 and 9480 series. LSI CVPM05 (05-50039-00) is a CacheVault flash cache protection module for Broadcom MegaRAID 9460 and 9480 series controllers – on a power failure the supercapacitor supplies energy for the controller to copy the DRAM cache to the module's NAND flash, and after power returns the data is restored and written to the disks, so write-back mode can stay enabled without fear. Unlike the old BBU batteries, the supercapacitor does not need replacing every couple of years and gives no end-of-life warnings, the module connects to the controller with the included cable and mounts in the server chassis with a bracket, and support covers the MegaRAID 9460-8i, 9460-16i, 9480-8i8e and similar models. It suits a data centre, a virtualisation host, a database server and a MegaRAID-based NAS where write speed and data integrity are needed at the same time. When buying a controller without CacheVault, add the module straight away – write-back without it is a risk, not a saving. Fast delivery across Latvia.
