IBM 190000, 250000 specs

Leadership enterprise server with significantly lower cost of ownership in a highly available and expandable, rack-dense, 1U dual-socket server

lets you keep your fingers on the pulse of your e-business.

Processors — The Intel Xeon processor provides high clock rates, dual- or quad-cores, 64-bit extensions, a large cache and advanced features for availability and manageability. Large cache size, combined with a fast 1333MHz or 1066MHz front-side bus, reduces memory latency and facilitates the movement of data through the processor and I/O devices. (Note: System performance depends not only on the number of processors in the server but also on the power and functionality of each processor.) Adding a second processor may be a cost-effective way to achieve significant performance improvements.

Memory — Memory is a significant factor in systems application performance. Adding more memory to a System x server is one of the most effective ways to increase application performance. For best performance in a server with a dual-core processor, there should be twice as much memory available as for a single-core processor.

Hard Disk Drives — IBM hard disk drives help you improve the transaction and cost performance of your System x servers. The choice of hard disk drives can be a critical aspect of maximizing the I/O throughput of the system. SAS hard disk drives are available for the x3550 M2 with capacities up to 300GB (2.5-inch) apiece at 10,000 RPMs, up to 146.8GB (2.5-inch) apiece up to 15,000 RPMs, or up to 73.4GB apiece (2.5-inch) at 15,000 RPM.

Power Supply — The optional second power supply for the x3550 M2 enables redundancy for hot-swap power.

Virtual Media Key — The x3550 M2 includes a plethora of systems management features built- in; however, sometimes additional management capability is needed. In those situations, the Virtual Media Key not only offers powerful new features, it does so without taking up a valuable PCI-X or PCIe adapter slot, instead using a dedicated slot on the motherboard.

ServeRAID Controllers — System x servers using ServeRAID BR10i technology allow companies to build a reliable foundation for business-critical computing. IBM ServeRAID technology allows an array consisting of multiple physical hard disk drives to be treated as one logical drive. ServeRAID technology also allows data to be stored redundantly, across multiple hard disk drives— enhancing both the integrity and the availability of the data. SAS and SATA ServeRAID controllers offer enhanced performance due to onboard processors and cache. Because IBM ServeRAID controllers can help significantly improve data transfer rates, this technology is extremely effective when implementing demanding, transaction-oriented applications. By employing the advanced fault tolerance of IBM ServeRAID technology, companies can effectively implement networked business systems that require large amounts of storage space for data and applications that must be available for their businesses to continue operating.

The optional MegaRAID-MR10i SAS/SATA controller offers enhanced performance over the integrated ServeRAID BR10i l controller (SAS models), 256MB of battery-backed cache memory, and supports six RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 1E (enhanced mirroring, supporting odd numbers of drives), 5 (striping with parity), and 6 (striping with double parity).

The optional MegaRAID MR10is supports hardware based full disk encryption plus RAID- 0/1/10/1E/5/6 support.

The optional MegaRAID MR10M SAS controller offers high performance and 256MB of cache memory (with optional battery backup) for external SAS storage capacity. The adapter supports five RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 5 (striping with parity), and 50 (striping/mirroring with parity).

External Storage — The IBM System Storage DS3000, DS4000, DS6000, and DS8000 series, as well as the N3000, N5000, and N7000 series, comprise a powerful and broad shared storage family with integrated management software designed to meet midrange and enterprise needs.

For lower-end needs, IBM offers the System Storage DS400 storage enclosure.

External SAN, iSCSI, and direct-attach storage is available using one of several IBM System Storage and TotalStorage host bus adapters. Additionally, external LAN-attached tape storage is available.

The iSCSI HBA Adapter for IXA Connectivity is a PCI adapter for selected System x servers that provides a direct 1GBps link to an IBM System i5 server. This connection enables you to centralize your Microsoft Windows and System i5 storage and consolidate the operations and backup of your System x, and System i5 systems into a single infrastructure. It enables the tightest possible integration between Windows and System i5/iSeries data and applications, and allows as many as 32 servers to attach to one System i5 system to share the iSeries server’s systems management, DVD, tape and disk storage via the iSeries dynamic virtual storage architecture. This can take the place of a SAN if you have an established System i5 infrastructure.
