Storage servers like having loads of RAM as it serves as a really fast cache. You should definently beef up your storage server in terms of RAM.

My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated:
Each Node:
Dell R210 Intel X3430 Quad Core 8GB RAM
Intel PT 1Gbps Server Dual Port NIC using linux "bonding"
Small pair of HDDs for OS (Probably in RAID1)
Each node will run about 10 - 15 customer guests
Storage Server:
Some Intel Quad Core Chip
2GB RAM (Maybe more?)
LSI 8704EM2 RAID Controller (Think this controller does 3 Gbps)
Battery backup for the above RAID controller
4 X RAID10 Arrays (4 X 1.5TB disks per array, 16 disks in total)
Each RAID10 array will connect to 2 nodes (8 nodes per storage server)
Intel PT 1Gbps Quad port NIC using Linux bonding
Exposes 8 X 1.5GB iSCSI targets (each node will use one of these)
HP Procurve 1800-24G switch to create 1 X 4 port trunk (for storage server), and 8 X 2 port trunk (for the nodes)
What you think? Any tips?
