Power Supply Features; Disk And Media Features; Sas Bays And Storage Backplane Options - IBM Power System E850C Technical Overview And Introduction

Note:
A machine type/model rack, if wanted, should be ordered as the primary rack.
Permanent Capacity on Demand (CoD) processor core activations are required for the
first processor module in the configuration and are optional for the second, third, and
fourth modules. Specifically:
– Two, three, or four 8-core #EPW4 require eight processor core activations (#EPW7)
– Two, three, or four 10-core #EPW5 require ten processor core activations (#EPW8)
– Two, three, or four 12-core #EPW4 require twelve processor core activations
A minimum of four memory features per processor module is required.
At least 50% of available memory or 128 GB of activations, whichever is larger, must be
activated through a combination of features #EMAA and #EMAB.
The language group is auto-selected based on geographic rules.

1.4.3 Power supply features

The following are the key power supply features:
(#EB3M) AC Power Supply - 2000 W for Server (200 - 240 VAC):
– One 200 - 240 V, 2000-watt ac power supply.
– The power supply is configured in a one-plus-one or two-plus-two configuration to
provide redundancy. Supported in rack models only.
– To be operational, a minimum of four power supplies in the server are required. During
a power supply failure, any of the power supplies can be exchanged without
interrupting the operation of the system.
(#EMXA) AC Power Supply Conduit for PCIe3 Expansion Drawer:
– Provides two 320-C14 inlet electrical connections for two separately ordered ac power
cords with C13 connector plugs. Conduit provides electrical power connection between
two power supplies in the front of a PCIe Gen3 I/O Expansion Drawer (#EMX0) and
two power cords that connect on the rear of the PCIe Gen3 I/O Expansion Drawer.
– A maximum of two per I/O Expansion Drawer #EMX0.

1.5 Disk and media features

This section describes the key disk and media features.

1.5.1 SAS bays and storage backplane options

Clients have a choice of three storage features with eight SFF disk bays, four x 1.8-inch disk
bays, and one DVD bay:
The Dual Controller Disk Backplane with write cache supports RAID 0, 1, 5, 6, 10, 5T2,
6T2, and 10T2 (#EPVN). The pair of controllers handles all 12 integrated SAS bays and
the DVD bay.
