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.
