IBM BladeCenter (E)

The original IBM BladeCenter was later marketed as BladeCenter E. Power supplies have been upgraded through the life of the chassis from the original 1200 to 1400, 1800, 2000 and 2320 watt. The BladeCenter (E) was co-developed by IBM and

IBM BladeCenter HT

BladeCenter HT is the telecommunications company version of the BladeCenter H, available with either AC or DC (48 V) power. Has 12 blade slots in 12U, but uses the same switches and blades as the regular BladeCenter H. But to keep NEBS Level 3 / ETSI compliant special NEBS compliant blades are available.

IBM BladeCenter S

Targets mid-sized customers by offering storage inside the BladeCenter chassis, so no separate external storage needs to be purchased. It can also use 120V power in the North American market, so it can be used outside the datacenter. When running at 120V , the total chassis capacity is reduced. Features: * 6 blade slots in 7U * Shared Media tray with optical drive and 2× USB 2.0 ports * 1 Advanced Management module as standard (no option for secondary module) * Storage: Up to 12 hot-swap 3.5" (or 24 2.5")

Modules

Switch modules

The BladeCenter can have a total of four switch modules, but two of the switch module bays can take only an Ethernet switch or Ethernet pass-though. To use the other switch module bays, a daughtercard needs to be installed on each blade that needs it, to provide the required SAN, Ethernet,

or Myrinet function. Mixing of different type daughtercards in the same BladeCenter chassis is not allowed.

Gigabit Ethernet switch modules were produced by IBM, Nortel, and

ranging in speeds of 1, 2, 4 and 8 Gbit Fibre Channel. Speed from the SAN switch to the blade is determined by the lowest-common-denominator between the blade HBA daughtercard and the SAN switch. External port counts vary from two to six, depending on the switch module.

InfiniBand

A InfiniBand switch module has been produced by Cisco. Speed from the blade InfiniBand daughtercard to the switch is limited to IB 1X (2.5 Gbit). Externally the switch has one IB 4X and one IB 12X port. The IB 12X port can be split to three IB 4X ports, giving a total of four IB 4X ports and a total theoretical external bandwidth of 40 Gbit.

Pass-through

Two kinds of pass-through module are available: copper pass-through and fibre pass-through. The copper pass-through can be used only with Ethernet, while the Fibre pass-through can be used for Ethernet, SAN or Myrinet.

Bridge

Bridge modules are only compatible with BladeCenter H and BladeCenter HT. They function like Ethernet or SAN switches and bridge the traffic to

. The advantage is that from the Operating System on the blade everything seems normal (regular Ethernet or SAN connectivity), but inside the BladeCenter everything gets routed over the

High-speed switch modules

High-speed switch modules are compatible only with the BladeCenter H and BladeCenter HT. A blade that needs the function must have a high-speed daughtercard installed. Different high-speed daughtercards cannot be mixed in the same BladeCenter chassis.

10 Gigabit Ethernet

A 10 Gigabit Ethernet switch module was available from BLADE Network Technologies. This allowed 10 Gbit/s connection to each blade, and to outside the BladeCenter.

InfiniBand 4X

There are several InfiniBand options: * A high-speed InfiniBand 4X SDR switch module from Cisco. This allows IB 4X connectivity to each blade. Externally the switch has two IB 4X ports and two IB 12X ports. The 12X ports can be split to three 4X ports, providing a total of eight IB 4X ports or a theoretical bandwidth of 80 Gbit. Internally between the blades, the switch is non-blocking. * A High-speed

pass-through module to directly connect the blades to an external

switch. This pass-though module is compatible with both SDR and DDR

speeds. * A high-speed InfiniBand 4X QDR switch module from Voltaire (later acquired by Mellanox Technologies). This allows full IB 4X QDR connectivity to each blade. Externally the switch has 16 QSFP ports, all 4X QDR capable.

Roadrunner TriBlade (custom module)

The IBM Roadrunner supercomputer used a custom module called the TriBlade from 2008 through 2013. An expansion blade connects two QS22 modules with 8 GB RAM each via 4 PCIe x8 links to a LS21 module with 16 GB RAM, two links for each QS22. It also provides outside connectivity via an
