I/O Sub System

I/O Modules

Hitachi engineers go to great lengths to design systems that provide high I/O throughput. BladeSymphony 1000 PCI I/O Modules deliver up to 160 Gb/sec. throughput by providing a total of up to 16 PCI slots (8 slots per I/O module). I/O modules accommodates industry standard PCIe or PCI-X cards, supporting current and future technologies as well as helping to preserve investments in existing PCI cards. In addition, by separating I/O from the server blades, the BladeSymphony 1000 overcomes the space contraint issues of other blade server designs, which can only support smaller PCI cards.

Three I/O modules are available: PCI-X I/O Module, PCIe I/O Module, and an Embedded Fibre Channel Switch Module. Two I/O modules are supported per chassis.

PCI-X I/O Module

The PCI-X I/O Module supports eight PCI-X cards in total, with a maximum of two PCI-X cards assigned to a single server blade for Chassis A and four for Chassis B. In Chassis A, eight PCI cards can be attached to four server blades, at a two-to-one ratio. In Chassis B, four PCI cards can be attached to four server blades for a four to one ratio. Hot plug is supported in specific conditions.

See the BladeSymphony 1000 Users Manual for more information. The block diagram for the PCI-X I/O Module is shown in Figure 16.
