IBM 5727 Integrated Cache - 40MB

IBM 5727 Integrated Cache - 40MB

• Internal controller for 9405/9406-520s
• 40MB Cache

IBM 5727 augments the base integrated disk controller of the model 515, 520, 525, or the model 550 with 40MB of write cache and also enables RAID-5 capability for the internal disk drives of the system unit. This feature is functionally equivalent to #5709 but can run in IOP-less mode. #5727 is installed into its own specific internal slot of a system unit and does not require a PCI slot. A minimum of three disk units are required for a RAID-5 disk array. CCIN is 573D.
