High-Performance Adapter Slots

The HX5 blade server includes two PCIe adapter slots. They support CFF (compact form factor)

cards: one standard-speed CIOv and one high-speed CFFh card. Note: The SSD expansion

card is installed in the upper I/O slot. When SSDs are installed, both I/O slots are still available

for use.

Adding a second HX5 blade for a 2-wide 4-socket server doubles the number of PCIe card slots.

The BladeCenter PCI Express I/O Expansion Unit 3 (BPE3) adds 2 standard full-height/full-

length x16 physical/x8 electrical (4GBps) PCIe Gen 1 expansion card slots, supporting adapters

of up to 25W apiece to an HX5. One BPE3 can be connected per HX5 blade, for a total of 3

available slots (1 in the blade and 2 in the expansion unit). Note: The BPE3 reserves the high-

speed CFFh expansion connector in the HX5, leaving only the CIOv slot available.

Similarly, the optional BladeCenter PCI Express Gen 2 Expansion Blade (BPE4) adds 1

standard full-height/full length and 1 standard full-height/half-length x16 physical/x8

mechanical (8GBps) PCIe Gen 2 expansion card slot per HX5 blade. These slots support two

industry-standard PCIe adapters, up to 75W per adapter. The BladeCenter PCI Express Gen 2

Expansion Blade offers a unique stacking feature that allows clients to stack up to 4 expansion

blades per HX5 blade, offering up to an additional 8 PCIe slots per HX5 blade. Note: Unlike the

BPE3, the BPE4 does not reserve the high-speed CFFh expansion connector in the HX5, leaving

both slots available in the server.

If I/O slots are a greater need than processors or memory, attaching multiple I/O expansion units

to one blade server is much more cost-effective than installing multiple blade servers for the

same number of adapter slots. (Note: A maximum of one CFFh card is supported.)

Adapters can be used to add fabrics to BladeCenter switch modules, including 10Gb Ethernet,

additional Gigabit Ethernet controllers, CNA, Fibre Channel, InfiniBand, SAS, etc.

Energy-Smart Features

HX5 servers work hard to keep your energy bills low—from lower-draw processors and memory

to solid-state drives. Technologies such as these, along with the Xeon E7 family and 7500/6500

series processors that intelligently adjust their voltage and frequency, help lower IT costs:

• 95W 8-core 7500 series and 6-core E7 processors use 27% less energy than 130W processors.

• 1.5V DDR3 DIMMs consume 10-15% less energy than 1.8V DDR2 DIMMs used in older servers.

• 1.35V DDR3 DIMMs consume up to 19% less energy than 1.5V DDR3 DIMMs.

• Solid-State Drives consume up to 80% less energy than 2.5-inch HDDs and up to 88% less than

3.5-inch HDDs.

• On a performance-per-watt basis, High IOPS SSD Adapters outperform enterprise HDDs by up to

445-to-1

BladeCenter Chassis

IBM’s blade architecture offers five choices of compatible and interoperable chassis in which to

use various blade servers. Each chassis serves different customer needs. The BladeCenter S is

a small, entry-level chassis designed for office environments. The original chassis (refreshed with

the latest Advanced Management Modules and power supply modules) offers maximum density,

great flexibility and a wide variety of expansion options at an entry-level price. The next-

generation BladeCenter H chassis offers all of BladeCenter’s capabilities, and adds high-

performance features, including 10Gb fabric support. If you need a ruggedized chassis (for

example, government/military or telecom), BladeCenter T offers special features optimized for

those environments. The next-generation BladeCenter HT is a high-performance ruggedized

telecommunications platform, also supporting 10Gb fabrics. HX5 is supported in the BladeCenter

H, BladeCenter HT and BladeCenter S chassis.

There is a high degree of interchangeability and compatibility of features among the chassis, and

all of these chassis can be installed in a rack along with other rack-optimized equipment.

See the separate IBM BladeCenter Chassis Product Guide for details.

Advanced Systems Management Capabilities

Each BladeCenter chassis offers a high level of systems management capabilities that are well-

suited to remote locations as well as to stand-alone environments. Features include the

Advanced Management Module (AMM), Integrated Management Module (IMM), IBM

ToolsCenter, Automatic Server Restart, Systems Director Active Energy Manager, Wake on LAN

support, PXE 2.0 support, text and graphics console redirect, Predictive Failure Analysis,

97,014 IOPS / 9W = 10,779 IOPS per watt (160GB/320GB adapters). 196,000 IOPS / 12W = ~16,333 IOPS per watt (640GB adapters). 400

IOPS / 16.5W = ~24 IOPS per watt (600GB 15K 3.5-inch hot-swap SAS HDD).
