Onboard RAID

With the RPX board installed on the system board, RAID software, and SCSI hard disk drives in the hot-docking bays, you can easily set up RAID applications. A two channel RAID solution can be constructed by installing an RPX module with RAID firmware resident in the RPX FLASH memory. The server system supports two types of embedded RAID firmware packages: I2O compliant and vendor proprietary firmware. The RAID features are as follows:

∙RAID levels 0, 1, 3, 5, 0+1, and JBOD

∙Support for hot spares, hot plugs, and user selectable rebuild rate

∙Support for multiple rebuilds across separate arrays and multiple consistency checks

∙Write back cache support with battery backup

∙Support for up to 2 terabytes per logical array and up to 64 terabytes of attached disk storage

∙Support for SAF-TE and SMART

Server System Board

ISA Expansion Slots

One of the ISA connectors shares a common chassis I/O expansion slot with a PCI connector; you can use either ISA or PCI in the slot, but not both.

The ISA bus operates at up to 8.33 MHz and provides

∙24-bit memory addressing

∙Type A transfers at 5.33 MB per second

∙Type B transfers at 8 MB per second

∙8- or 16-bit data transfers
