Announcement ZG14-0098

IBM is a registered trademark of International Business Machines Corporation

– Two 12-core, 3.52 GHz processor (#EPXH) requires that twenty-four processor

activation codes be ordered. A maximum of twenty-four processor activation

code feature EPYE is required.

System memory

• A minimum 32 GB of memory is required on the Power S824 system.

• Memory is required to be ordered in pairs. Base memory is two 16 GB, 1600

Mbps DDR3 memory modules (#EM8B).

Plans for future memory upgrades should be taken into account when deciding which

memory feature size to use at the time of initial system order.

Power supply

Four power supplies: 2+2 900 Watt 100-127 V ac or 200-240 V ac options (4 x

#EB2L)

Redundant fans

Redundant fans are standard.

Power cords

Four power cords are required. A maximum of four feature 6458 cords are allowed

on the system unless a valid I/O drawer or tower is attached to the system. The

Power S824 supports power cord 4.3m (14-ft), Drawer to Wall/IBM PDU (250V/10A)

in the base shipment group. Refer to the feature listing for other options.

I/O support

PCIe slots

The Power S824 has up to 11 PCIe hot plug Gen 3 slots, providing excellent

configuration flexibility and expandability. For even more PCIe slots, see the

Statement of general direction section for an I/O drawer with PCIe slots.

With two POWER8 processor DCMs, 11 PCIe Gen 3 slots are available. Four are x16

full-height and full-length slots. Seven are x8 Gen 3 full-height, half-length slots.

With one POWER8 processor DCM, seven PCIe Gen 3 slots are available. Two are

x16 full-height and full-length slots. Five are x8 Gen 3 full-height, half-length slots.

Four other PCIe slots are physically present, but are not available for use until a

second processor DCM is installed.

The x16 slots can provide up to twice the bandwidth of x8 slots because they offer

twice as many PCIe lanes. PCIe Gen 3 slots can support up to twice the bandwidth

of a PCIe Gen 2 slot and up to four times the bandwidth of a PCIe Gen 1 slot,

assuming an equivalent number of PCIe lanes.
