Intensive Processing Blades with Write Cache

topokin — Fri, 27 May 2011 08:43:23 GMT

We are trying procuring some BL460 as power processing systems. All Source data and the eventually output will not be local but rather be accessed on a file-server. Only the OS and the processing application will be local within the processing systems themselves.

Since the required Input / Output data will not be local, is there any need for “Flash Backed Write Cache” module? Would there be any performance gain in having one in such configuration?

Thanks

In this configuration the FBWC will add no performance gain. You can use internal SA P410i/ZM (zero memory).

Thanks for the response.

Unfortunately the Processing software requires a Windows FileServer and one of the blades will serve that purpose. Only the data are not also local on this FileServer but through connection to an iSCI NetApp NAS-Storage.

Since the Data-Disks are not physically local on this FileServer, could it be concluded as well that FBWC will be of no use.

Yes, FBWC will play only with local disks.
