Compatibility
The IBM 5778 PCI-X EXP24 Controller is compatible with IBM Power Systems models, specifically 8203-E4A, 8204-E8A, 8205-E6B, 9406-MMA, and 9406-570, as verified for their PCI-X slot support. It connects to #5786/#5787 TotalStorage EXP24 Disk Drawers or #5796 PCI-DDR 12X Expansion Drawers via three Ultra320 SCSI ports, supporting IBM i, AIX, and Linux. The controller requires two adjacent PCI-X slots and does not use an IOP. In logical partition environments, both slots must be assigned to the same partition. It is not compatible with non-PCI-X slots or unsupported disk drawers. Ideal for high-performance storage expansion, it supports enterprise applications like virtualization and database management, ensuring scalability and reliability.
