The Power 740 Server - IBM Power 720 Overview

The Capacity Backup (CBU) designation, offered for the Power 720 system, can help meet
your requirements for a second system to use for backup, high availability, and disaster
recovery. It enables you to temporarily transfer IBM i processor license entitlements and IBM i
user license entitlements purchased for a primary machine to a secondary
CBU-designated system. Temporarily transferring these resources instead of purchasing
them for your secondary system might result in significant savings. Processor activations
cannot be transferred.

1.1.2 The Power 740 server

The IBM Power 740 server is a 4U rack-mount with two processor sockets that offer 6-core
4.2 GHz, 8-core 3.6 GHz, and 8-core 4.2 GHz processor options. The POWER7+ processor
chips in this server are 64-bit, 6-core, and 8-core modules with 10 MB of L3 cache per core
and 256 KB of L2 cache per core.
The Power 740 server supports a maximum of 32 DDR3 DIMM slots, with eight DIMM slots
included in the base configuration and 24 DIMM slots available with three optional memory
riser cards. A system with three optional memory riser cards installed has a maximum
memory of 1024 GB.
The Power 740 system includes an integrated SAS controller, offering RAID 0, 1, and 10
support, and two storage backplanes are available. The base configuration supports up to six
SFF SAS HDDs or SSDs, an SATA DVD, and a half-high tape drive. A higher-function
backplane is available as an option. This option supports up to eight SFF SAS HDDs or
SSDs, an SATA DVD, a half-high tape drive, Dual 175 MB Write Cache RAID with RAID 5 and
RAID 6 support, and an external SAS port.
All HDDs or SSDs are hot-swap and front accessible. If the internal storage capacity is not
sufficient, additional disk I/O drawers can be attached to the system unit, providing large
storage capacity and multiple partition support.
