The enclosures can be connected in a fully redundant manner, which provides a
very high level of availability. On the host side FC connections, you can use up to
four mini-hubs.
This allows you to establish up to eight host connections without needing an
external hub or a switch. For performance and availability, each RAID controller
unit contains 256 MB of battery-backed cache and this amount can be further
expanded.
The IBM TotalStorage FAStT700 Storage Server
The FAStT700 Storage Server is the newest addition to the FAStT range of
products. As with the FAStT 500 Storage Server, you would typically implement
the FAStT 700 Storage Server in high-end cluster and server consolidation
environments and where multiple servers are being consolidated onto a smaller
number of x440 systems.
It is the same physical size as the FAStT500 with new higher performance
controllers. These new controllers are 2 Gbps and connect via mini-hubs to the
new FAStT FC-2 Host Bus Adapter (HBA) and the new 2109 F16 Fibre Channel
switch to give full 2 Gbps fabric.
Like the FAStT500 it attaches to up to 220 FC disks via 22 EXP500 expansion
units or up to 224 FC disks via 16 EXP700 expansion units to provide scalability
for easy growth (18 GB up to 16 TB using 73 GB drives). To avoid single points of
failure, it also features dual hot-swappable RAID controllers, dual redundant FC
disk loops, write cache mirroring, redundant hot-swappable power supplies, fans,
and dual AC line cords.
Using the new FAStT Storage Manager Version 8.21, it supports FlashCopy,
Dynamic Volume Expansion and Remote Mirroring with controller-based support
for up to 64 storage partitions. RAID levels 0,1, 3, 5, and 10 are supported and
for performance it includes a total of 2 GB battery-backed cache (1 GB per
controller).
Note: The FAStT700 is currently the only certified storage solution for the
x440 in the 16-way and Microsoft clustered configurations. To check the
Microsoft Hardware Compatibility List (HCL) for updates to certified solutions,
