ServeRAID-4Lx features one Ultra160 SCSI channel, 32 MB of ECC cache memory, and an Intel i80303 processor. Up to 14 Ultra160 and Ultra2 SCSI devices are supported. Each ServeRAID adapter supports up to 14 drives (and 160 MB per second throughput) per channel (for an aggregate of up to 56 drives and 640 MBps for the 4-channel ServeRAID-4H adapter, for example). Multiple adapters can be installed as needs and available slots dictate. The EXP300 storage expansion unit has a maximum 1 TB of disk storage (14 73.4 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 units can hold an amazing 14 TB). The EXP300 provides 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.

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 three products: The IBM TotalStorage FAStT200 Storage Server The IBM TotalStorage FAStT500 Storage Server The IBM TotalStorage FAStT700 Storage Server The IBM TotalStorage FAStT200 Storage Server The FAStT200 Storage Server is a 3U rack-mountable Fibre Channel RAID controller and disk drive enclosure. It targets the entry and midrange segment of the FC storage market. A typical use of the FAStT200 would be in a two-node cluster environment with up to 30 Fibre Channel disk drives attached to the Storage Server. Two models are available: The FAStT200 Storage Server, with a single RAID controller. Chapter 3. Planning 85
