Table 4. Chassis support

* See Table 5 for details

The number of HS22 servers supported in each chassis depends on the thermal design power of the processors used in the servers, as shown in Table 5. The table uses the following conventions:

• A green cell means the chassis can be filled with HS22 blade servers up to the maximum number of blade bays in the chassis (for example, 14 blades in the BladeCenter H).
• A yellow cell means that the maximum number of HS22 blades that the chassis can hold is fewer than the total available blade bays (for example, 12 in a BladeCenter H). Other bays in the chassis may or may not be occupied by servers other than HS22 and HS22V depending on the combination and some bays must remain empty. Consult the BladeCenter Interoperability Guide for specifics: http://lenovopress.com/bcig.

Lenovo DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput. Memory specifications are integrated into the light path diagnostics for immediate system performance feedback and optimum system uptime. From a service and support standpoint, Lenovo memory automatically assumes the system warranty.

The HS22 has six DIMM sockets per processor (12 DIMMs in total) and uses Double Data Rate-3 (DDR-3) very-low-profile (VLP) registered DIMMs. Servers with Intel Xeon 5600 series processors support 16GB DIMMs meaning a total of up to 192 GB of RAM is supported. Servers with Intel Xeon 5500 series processors support 8GB DIMMs meaning a total of up to 96 GB of RAM is supported. The memory DIMMs connects directly to one of the processors. With one processor installed, only six DIMMs can be accessed. To access memory in the other six DIMM connectors, the second processor must be installed.

The following two tables list memory options available for HS22 server: one of 5500 series processors and one for 5600 series processors. DIMMs can be installed one at a time, but for performance reasons, install them in sets of three (one for each of the three memory channels).

Note that although the maximum speed at which the memory channel runs on the HS22 is 1333 MHz, this depends on a combination of three items:

• Processor memory speed: The processor has a maximum memory speed of 1333, 1066, or 800 MHz depending on the processor model. Only the X (Advanced) range of Xeon 5500 and 5600 series processors supports a maximum memory channel speed of 1333 MHz. See the processor options (Table 5) for the maximum memory speed.
• Memory DIMM: Most but not all DIMMs listed in the previous tables support running at 1333 MHz. Some only run at 1066 MHz. This is noted in the description of the DIMM.
• Number of DIMMs installed: The HS22 implements memory so that 2 DIMMs are on each of the three memory channels of the processor. if only 1 DIMM is installed to each channel (that is, 3 DIMMs per processor) then the DIMMs can operate at the lower of the DIMM rated speed and processor memory channel rated speed, up to 1333 MHz. However at 2 DIMMs per channel (6 DIMMs per processor), memory can only operate at 1333 MHz if Xeon 5600 X (Advanced) range of processors (models X56nn) are installed. All other processors (all 5500, L56nn, and E56nn) cannot drive the memory channel at 1333 MHz if there are 2 DIMMs per channel.

In summary, to ensure DIMMs operate at 1333 MHz, select a Xeon X56nn processor and use DIMMs that are rated at 1333 MHz. All DIMMs in the proceeding table support running at 2 DIMMs per channel at 1333 MHz.

The following memory protection technologies are supported:

• ECC
• ChipKill
• Memory Mirroring
• Memory Sparing

The HS22 blade server features an onboard LSI Logic 53C1064E 3 Gbps SAS controller with two hot-swap drives bay accessible from the front of the blade server. The LSI Logic 53C1064E SAS controller provides RAID 0 or RAID 1 capability and supports up to two internal hot-swap SAS or SATA HDDs or two internal hot swap solid-state drives. The following table lists the hard drive options that are available for internal storage.

The server does not support an internal tape drive option.

The server does not support an optical drive option, however it does interface to the optical drive installed in the BladeCenter chassis media tray if one is installed there.

The HS22 server offers the following PCI Express 2.0 slots, neither of which is hot-swap.

• CIOv expansion slot
• CFFh expansion slot

The CIOv I/O expansion connector provides I/O connections through the midplane of the chassis to modules located in bays 3 and 4 of a supported BladeCenter chassis. It is a PCIe 2.0 x8 slot.

The CFFh I/O expansion connector provides I/O connections to high-speed switch modules that are located in bays 7, 8, 9, and 10 of a BladeCenter H or BladeCenter HT chassis, or to switch bay 2 in a BladeCenter S chassis. The CFFh slot is a PCIe x16 slot.

The HS22 optionally supports the BladeCenter PCIe Gen 2 Expansion Blade. The expansion blade provides the capability to attach selected PCI Express cards to the HS22. This capability is ideal for many applications that require special telecommunications network interfaces or hardware acceleration using a PCI Express card.

The expansion blade provides one full height and full length PCI Express slot and one full height and half length PCI Express slot with a maximum power usage of 75 watts for each slot. It integrates PCI Express card support capability into the BladeCenter architecture. Up to four expansion blades can be attached to an HS22. Each expansion blade occupies a bay in the BladeCenter chassis.

The server also supports BladeCenter PCI Express I/O Expansion Unit (PCI Express Gen 1). A maximum of one unit can be attached to a single blade.
