xSeries 455 Planning and Installation Guide
The ServeRAID-6M is a 133 MHz PCI-X adapter and features two Ultra320
SCSI channels, according model 128 MB or 256 MB of battery-backed up
ECC SDRAM cache memory, and an Intel 600 MHz xScale processor. Up to
28 Ultra320, Ultra160 and Ultra2 SCSI devices are supported.
Each ServeRAID adapter supports up to 14 drives (4Mx have 160 MBps
throughput and 6M has 320 MBps throughput) per channel. Multiple adapters
can be installed as needs and available slots dictate.
The EXP300 and the new EXP400 storage expansion units have a maximum
2 TB of disk storage (14 146.8 GB drives) in a 3U package, allowing up to 14
expansion units to be used in a standard 42U rack (meaning that a full rack of
EXP300 or EXP400 units can hold an amazing 28 TB). EXP300 and EXP400
provide Predictive Failure Analysis (PFA) on key components, including
hot-swap fans, hard drives, and redundant power supplies. The EXP300 is
optimized for Ultra160 SCSI, with a sustained data transfer rate of 160 MBps,
and the new EXP400 is optimized for Ultra320 SCSI, with a sustained data
transfer rate of 320 MBps.

IBM TotalStorage® FAStT
The IBM TotalStorage FAStT (Fibre Array Storage Technology) family of Fibre
Channel storage solutions is designed for high-availability, high-capacity
requirements. FAStT solutions can support transfers over distances up to 10 km
(6.2 miles) at rates of up to 200 MBps.
The FAStT Storage Server is a RAID controller device that contains Fibre
Channel (FC) interfaces to connect the host systems and the disk drive
enclosures. The Storage Server provides high system availability through the use
of hot-swappable and redundant components. We briefly discuss the following
products:
The IBM TotalStorage FAStT200 Storage Server
The IBM TotalStorage FAStT500 Storage Server
The IBM TotalStorage FAStT600 Storage Server
The IBM TotalStorage FAStT700 Storage Server
The IBM TotalStorage FAStT900 Storage Server
