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.
Intel Advanced Vector Extensions (AVT) can significantly improve floating point performance for
compute-intensive technical and scientific applications.
Up to 16 DDR3 ECC memory RDIMMs provide speeds up to 1600 MHz and a memory capacity of up
to 512 GB. (See Table 7 for details.)
The theoretical maximum memory bandwidth of the Intel Xeon processor E5 family is 51.6 GBps,
which is 60% more than in the previous generation of Intel Xeon processors.
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 up to 100 times more I/O operations per
second (IOPS) than a typical HDD.
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.
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 previous
generation of PCI Express 2.0 (5 GTps per link using 8b/10b encoding).
generation of 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.
performance.
Manageability and security
Powerful systems management features simplify local and remote management of the HS23:
The HS23 includes an Integrated Management Module II (IMM2) to monitor server availability and
perform remote management.
Integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup,
configuration, and updates, and simplifies error handling.
Integrated Trusted Platform Module (TPM) 1.2 support enables advanced cryptographic functionality,
such as digital signatures and remote attestation.
Industry-standard AES NI support for faster, stronger encryption.
IBM Systems Director is included for proactive systems management. It offers comprehensive
systems management tools that help to increase up-time, reduce costs, and improve productivity
through advanced server management capabilities.
through advanced server management capabilities.
IBM Fabric Manager simplifies deployment of infrastructure connections by managing network and
storage address assignments.
IBM FastSetup simplifies, automates, and speeds up the deployment process from server power-up
to production, making BladeCenter easier to manage, deploy, and maintain.
Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
Intel Trusted Execution Technology provides enhanced security through hardware-based resistance
to malicious software attacks, allowing an application to run in its own isolated space protected from
all other software running on a system.
