Smart Array 641 Controller - Expansion

[madman045]

Can anyone help me, I am currently looking to add to the existing controller, a HP BBWC Enabler - Memory - 128 MB - DDR to it, however is this all I need, or would I need to also purchase a HP Battery Backed Write Cache Enabler Option Kit - Memory backup battery to go with it

Being as it's quite an old product, HP has very little documentation.

Current server is extremely slow for around 15 users, mixture of PCs and Macs, accessing CAD drawings, JPGs and email

Thanks

Thanks Gord, yes it was confusing as the description of the memory unit only mentions the ram and not the battery and I couldnt find a picture to confirm it.

The controller currently has three 146gb 10k SCSI drives in Raid 5, need to improve the performance as its struggling so I was going to add the 128mb unit as its quite cheap these days

Thanks
