Key features
The IBM BladeCenter HS23 gives you the networking capacity that you need to manage your data center.
The new 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 Gb 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 256 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 5 for compatibility details.)
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 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.
The power source independent light path diagnostics panel and individual light path LEDs quickly
lead the technician to failed (or failing) components. This simplifies servicing, speeds up problem
resolution, and helps improve system availability.
The Predictive Failure Analysis (PFA) detects when system components (processors, memory, and
hard disk drives) operate outside of standard thresholds and generates pro-active alerts in advance of
possible failure, therefore increasing uptime.
Solid-state drives (SSDs) offer significantly better reliability than traditional mechanical HDDs for
greater uptime.
Built-in Integrated Management Module II (IMM2) continuously monitors system parameters, triggers
alerts, and performs recovering actions in case of failures to minimize downtime.
Built-in diagnostics using Dynamic Systems Analysis (DSA) Preboot speeds up troubleshooting tasks
to reduce service time.
Three-year customer replaceable unit and onsite limited warranty, next business day 9x 5. Optional
service upgrades are available.
Scalability and performance
The BladeCenter HS23 offers numerous features to boost performance, improve scalability, and reduce
costs:
The Intel Xeon processor E5-2600 product family improves productivity by offering superior system
performance with up to 8-core processors and up to 3.0 GHz core speeds depending on the CPU's
number of cores, up to 20 MB of L3 cache, and QPI interconnect links of up to 8 GT/s.
Up to two processors, 16 cores, and 32 threads maximize the concurrent execution of multi-threaded
applications.
Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows CPU cores
to run at maximum speeds during peak workloads by temporarily going beyond processor TDP.
