options, and a PCI-E unique connector to enable the installation of a High-Speed I/O Expansion Card (HSDC) adapter, or a PCI Expansion Unit. The SIO storage subsystem is a self-contained intelligent RAID solution, consisting of an I/O Processor (IOP), a cache memory, or an optional battery-backed data cache, and support for up to three SFF hot-swap Serial Attached SCSI (SAS) hard drives. To accommodate this feature, the BladeCenter PCI-E option interface connector is defined with two SAS links which are connected to the secondary ports of the SAS drives on the processor blade. Both form factors of BladeCenter PCI-X adapter options (large and small) are supported; however, the PCI-E connector on the topside of the SIO allows another BladeCenter PCI-E option to be attached, such as a high-speed I/O expansion card, or a PCI Expansion Unit. Either two PCI-X adapter options (in any combination of small or large form factor) or one PCI-X adapter (large or small) and one HSDC can be supported. Features of the BSE-3 blade include: RAID support: The SIO provides RAID levels 0 and 1, along with all supported RAID 0 and 1 sublevels. Optional support (25R8064), which replaces the base RAID support, adds battery-backed data cache and support for RAID 5 and all supported RAID 5 sublevels. Hard drives: The BSE-3 blade delivers three bays for hot-swap, 2.5-inch SFF SAS hard drives (39R7388, 39R7389, and 43X0832). The SAS interface will run at up to 3.0 Gbps, full duplex. Drives are mounted on hot-swap trays and will fit side-by-side across the front of the option blade. All three drive bays must be populated with either a drive or a blank tray insert. Drives include 73 GB and 146 GB. These drives can be mixed or matched as needed. Only drives and tray inserts released for BSE-3 blade may be used in this option. I/O expansion card option support: The BSE-3 blade supports the addition of I/O expansion cards, both PCI-X and PCI-E. PCI-X Slots 1 and 2 Both slots support either legacy or SFF I/O expansion cards. Slot 1 will reside on PCI-X bus A, and the two SERDES channels from this slot will route to BladeCenter Storage and I/O Expansion Blade positions 1 and 2. Slot 2 will reside on PCI-X bus B, and the two SERDES channels from this slot will route to BladeCenter Storage and I/O Expansion Blade positions 3 and 4. PCI-E High-Speed I/O Expansion Card (HSDC) The HSDC options will be designed to use PCI-E link B. PCI-E attached Expansion Card (HSDC) electrically interfaces directly to the host blade that the SIO is attached to. The power budget for the HSDC option is 25 watts, maximum. HSDC options supported include the Cisco 4xIB Host Channel Adapter Expansion Card (32R1760). The BSE-3 blade will support a maximum of any two I/O expansion card options.

No moving parts means potentially fewer points of failure, lower power consumption, and less heat. The modular flash drive can be used instead of, or in conjunction with, a traditional hard disk for booting and low bandwidth/local storage. Similar to a traditional disk drive, the solid state storage can be used as a boot device, and can perform regular storage functions. It is not recommended for high bandwidth applications such as file serving, Web serving, and mail. Support as a boot drive is limited to Linux. Under the Windows operating systems, the IBM 4 GB and 8 GB Modular Flash Drive options are limited to usage as a local data drive. Security, auditability, and control Security and auditability features include: A power-on password function helps provide control of who has access to the data and server setup program on the server. A set unattended boot mode allows the system keyboard to be locked to all entries except the password and at the same time allows other computers on the network to access the system disk drive. A selectable boot sequence can be used to help prevent unauthorized installation of software or removal of data from the diskette drive. The BladeCenter HS21 XM blades have no security intrusion detection. therefore, they should be installed in a rack environment that provides security through lockable doors or other security measures. It is the client's responsibility to ensure that the server is secure to protect sensitive data.

IBM Electronic Services IBM has transformed its delivery of hardware and software support services to help you achieve higher system availability. Electronic Services is a Web-enabled solution that offers an exclusive, no-additional-charge enhancement to the service and support available for IBM servers. These services are designed to provide the opportunity for greater system availability with faster problem resolution and preemptive monitoring. Electronic Services comprises two separate, but complementary, elements: Electronic Services news page and Electronic Services Agent. The Electronic Services news page is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems. The Electronic Service Agent is no-additional-charge software that resides on your server. It monitors events and transmits system inventory information to IBM on a periodic, client-defined timetable. The Electronic Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to deliver proactive service that may result in higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they help answer your questions or diagnose problems. Installation and use of IBM Electronic Service Agent for problem reporting enables IBM to provide better support and service for your IBM server.
