Key features

The BladeCenter HS23 gives you the networking capacity that you need to manage your data center. The

Virtual Fabric capable integrated 10 GbE offers extreme speed, and the HS23 is designed with highly

scalable I/O to give you a total of up to four 10 GbE physical ports that can be divided into up to 14 virtual

ports, as well as the ability to run multiple I/O protocols (FCoE, iSCSI). Sixteen DIMM slots supporting up

to 512 GB of DDR3 memory allow you to fit more and larger virtual machines per blade. In addition, the

HS23 is backward-compatible with all BladeCenter chassis, including the original BladeCenter E. (Some

configurations might have restrictions. See Table 4 for compatibility details.)

Scalability and performance

The BladeCenter HS23 (7875, E5-2600 v2) offers numerous features to boost performance, improve

scalability, and reduce costs:

The Intel Xeon processor E5-2600 v2 product family improves productivity by offering superior

system performance with up to 12-core processors (up to 2.7 GHz core speeds) or up to 3.5 GHz

core speeds (4-core processors), up to 30 MB of L3 cache, and QPI interconnect of up to 8 GT/s.

Up to two processors, 24 cores, and 48 threads maximize the concurrent execution of multi-

threaded applications.

Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows

processor cores to run at maximum speeds during peak workloads by temporarily going beyond

processor TDP.

Intel Hyper-Threading Technology boosts performance for multi-threaded applications by enabling

simultaneous multi-threading within each processor core, up to two threads per core.

Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating

system vendors to better utilize the hardware for virtualization workloads.

Up to 16 DDR3 ECC memory RDIMMs provide speeds up to 1866 MHz and a memory capacity of

up to 512 GB. (See Table 6 for details.)

The use of solid-state drives (SSDs) instead of or along with traditional spinning drives (HDDs) can

significantly improve I/O performance. An SSD can support significantly more I/O operations per

second (IOPS) than a typical HDD.

The HS23 scales to 18 I/O ports on a single-wide blade with integrated Gigabit Ethernet and 10 Gb

Ethernet ports and optional expansion cards, offering the choice of Ethernet, Fibre Channel, SAS,

iSCSI, and FCoE connectivity.

The HS23 offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum

bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to the PCI

Express 2.0 (5 GTps per link using 8b/10b encoding).

With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon

processor E5 family. This helps to dramatically reduce I/O latency and increase overall system

performance.

Availability and serviceability

The BladeCenter HS23 provides many features to simplify serviceability and increase system uptime:

Dual independent power and signal connectors to the BladeCenter chassis midplane provide fault

tolerance to increase uptime.

The HS23 offers Chipkill, memory mirroring, and memory rank sparing for redundancy in the event

of a non-correctable memory failure.

Tool-less cover removal provides easy access to upgrades and serviceable parts, such as CPU,

memory, and adapter cards.

The server offers hot-swap drives supporting integrated RAID 1 redundancy for data protection and

greater system uptime.
