Chapter 3. Introduction to IBM Flex System 49
Management One or two Chassis Management Modules, for basic chassis management.
Two CMMs form a redundant pair; one CMM is standard in 8721-A1x. The
CMM interfaces with the integrated management module (IMM) or flexible
service processor (FSP) integrated in each compute node in the chassis.
There is an optional IBM Flex System Manager management appliance for
comprehensive management, including virtualization, networking, and
storage management.
I/O architecture Up to 8 lanes of I/O to an I/O adapter, with each lane capable of up to 16
Gbps bandwidth. Up to 16 lanes of I/O to a half wide-node with two adapters.
There are a wide variety of networking solutions, including Ethernet, Fibre
Channel, FCoE, and InfiniBand
Power supplies Six 2500-watt power modules that provide N+N or N+1 redundant power; two
power modules are standard in model 8721-A1x. The power supplies are
80 PLUS Platinum certified and provides 95% efficiency at 50% load and
92% efficiency at 100% load. There is a power capacity of 2500 W output
rated at 200 VAC. Each power supply contains two independently powered
40 mm cooling fan modules.
Fan modules Ten fan modules (eight 80 mm fan modules and two 40 mm fan modules);
Four 80 mm and two 40 mm fan modules are standard in model 8721-A1x.
