• 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 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.

Scalability and performance

The 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 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.

Lenovo DDR3 memory is compatibility tested and tuned for optimal System x® and BladeCenter performance and throughput. Lenovo 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 Lenovo system warranty, and Lenovo provides service and support worldwide.

The BladeCenter HS23 (E5-2600) supports Very Low Profile (VLP) DDR3 memory RDIMMs. The server supports up to eight DIMMs when one processor is installed and up to 16 DIMMs when two processors are installed. Each processor has four memory channels, and there are two DIMMs per channel.

The following rules apply when selecting the memory configuration:

• Mixing 1.5 V and 1.35 V DIMMs in the same server is supported. In such a case all DIMMs operate at 1.5 V.
• The maximum number of ranks supported per channel is eight.
• The maximum quantity of DIMMs that can be installed in the server depends on the number of CPUs, DIMM rank, and operating voltage, as shown in the "Max. qty supported" row in Table 6.
• All DIMMs in all CPU memory channels operate at the same speed, which is determined as the lowest value of:
  • Memory speed supported by specific CPU
  • Lowest maximum operating speed for the selected memory configuration that depends on rated speed, as shown under the "Maximum operating speed" section in Table 6.

* Maximum quantity supported is shown for two processors installed. When one processor is installed, the maximum quantity supported is half of what is shown.

The following memory protection technologies are supported:

• ECC
• Chipkill
• Memory mirroring
• Memory rank sparing

If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per CPU), and both DIMMs in a pair must be identical in type and size. The effective memory available to the system is only half of that installed.

If memory rank sparing is used, then two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need to be identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs installed.

Chipkill, memory mirroring, and memory rank sparing modes are mutually exclusive. Only one operational memory mode can be enabled on a server, and it is a system-wide setting.

The HS23 server has two hot-swap drive bays accessible from the front of the blade server. These bays are connected to the integrated 4-port LSI SAS2004 6 Gbps SAS/SATA RAID-on-Chip (ROC) controller.

Lenovo Financial Services offers financing solutions and services that complement your technology solution anywhere in the world.

We are dedicated to delivering a positive finance experience for customers like you who want to maximize your purchase power by obtaining the technology you need today, protect against technology obsolescence, and preserve your capital for other uses.

We work with businesses, non-profit organizations, governments and educational institutions to finance their entire technology solution. We focus on making it easy to do business with us. Our highly experienced team of finance professionals operates in a work culture that emphasizes the importance of providing outstanding customer service. Our systems, processes and flexible policies support our goal of providing customers with a positive experience.

We finance your entire solution. Unlike others, we allow you to bundle everything you need from hardware and software to service contracts, installation costs, training fees, and sales tax. If you decide weeks or months later to add to your solution, we can consolidate everything into a single invoice.

Our Premier Client services provide large accounts with special handling services to ensure these complex transactions are serviced properly. As a premier client, you have a dedicated finance specialist who manages your account through its life, from first invoice through asset return or purchase. This specialist develops an in-depth understanding of your invoice and payment requirements. For you, this dedication provides a high-quality, easy, and positive financing experience.

For your region specific offers please ask your Lenovo sales representative or your technology provider about the use of Lenovo Financial Services. For more information, see the following Lenovo website:
