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 x450 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, the FAStT700 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 32.6 TB using 146.8 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.
FAStT Storage Manager Version 8.21 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).
Restriction: At the time of writing, there was no 64-bit version of FAStT
Storage Manager. Consequently, all configuration and management must be
performed remotely.

Enterprise Storage Server (ESS)
ESS provides integrated caching and RAID support for the attached disk devices.
ESS can be configured in a variety of ways to provide scalability in capacity and
performance. One ESS can support in excess of 28 TB and can utilize 2 Gbps
Fibre Channel connectivity.
Redundancy within ESS provides continuous availability. It is packaged in one or
more enclosures, each with dual line cords and redundant power. The redundant
power system allows ESS to continue normal operation when one of the line
cords is deactivated.
ESS provides an image of a set of logical disk devices to attached servers. The
logical devices are configured to emulate disk device types that are compatible
with the attached servers. The logical devices access a logical volume that is
