IBM x3200 Product Guide - Page 4

An affordable single-socket, dual-core server with high performance and data protection for small and medium businesses Hot-Swap/Redundant Components System availability is maximized through the use of hot-swap and redundant components, including: • Hot-swap/redundant or simple-swap hard disk drives (with RAID-1/1E protection standard) • Hot-swap, redundant power supplies (optional, model-specific) Disk/Tape Controllers Some x3200 M2 models include an integrated four-port LSI 1064e SAS/SATA controller. Other x3200 M2 models include a SATA controller only, integrated into the Intel chipset. (All models provide a dedicated internal SATA port for a GoVault removable disk backup device.) The integrated controller in all hot-swap models supports up to four 3.5-inch or eight 2.5-inch internal SAS LVD (low-voltage differential) hot-swap drives standard , and provides data transfer speeds of up to 300MB per second4 in each direction (full-duplex) for SAS drives, for an aggregate speed of 600MBps, nearly double that of Ultra320 SCSI's 320MBps (half-duplex) bandwidth. The serial design of the SAS bus allows maximum performance to be maintained as additional drives are added. This controller also supports up to four Serial ATA (SATA) drives at 300MBps (half-duplex). The integrated controller in the hot-swap models offers hardware RAID-0/1/1E support for SAS or SATA drives. An optional ServeRAID-MR10i controller can be added for RAID-10/5/6 support, as well as optional battery backup with 256MB of cache memory. The simple-swap SATA models offer an integrated SATA controller, which supports up to four internal simple-swap LVD SATA drives at the same 300MBps (half-duplex) throughput. Large HDD Storage Capacity The x3200 M2 offers a choice of disk storage, supporting up to four 3.5-inch simple-swap Serial ATA (SATA) drives or four 3.5-inch hot-swap high-performance Serial-Attach SCSI (SAS) or SATA drives, or up to eight 2.5-inch hot-swap SAS drives. SAS 3.5-inch Hot-Swap • 10,000 RPMs - 73.4, 146.8 or 300GB (1.2TB maximum) • 15,000 RPMs - 73.4 or 146.8GB (587.6TB) SATA 3.5-inch Simple-Swap or Hot-Swap • 7,200 RPMs - 160, 250, 500 or 750GB (3.0TB) SAS 2.5-inch Hot-Swap • 10,000 RPMs - 73.4, or 146.8GB (1.174TB maximum) Notes: Enterprise-class 500GB or higher SATA drives offer increased reliability compared to lowercapacity SATA drives. Hot-swap SAS drives use the Converged Tray for interchangeability with other IBM System x™ and IBM eServer™ xSeries® systems. If you need more storage space, terabyte capacities are possible with external direct-attach, NAS and SAN solutions. Drive Bays Some x3200 M2 models contain 7 drive bays standard (3.5-inch HDD models), while others provide 11 drive bays (2.5-inch models). All models offer two 5.25-inch bays, one 3.5-inch floppy drive bay, and either four 3.5-inch HDD bays or eight 2.5-inch HDD bays. Some models support up to four hot-swap SAS or SATA drives; other models support up to four simple-swap SATA drives. An optical drive (48X/32X/48X/16X CD-RW/DVD-ROM Combo drive) with a SATA interface ships standard in one 5.25-inch bay. The other 5.25-inch bay supports one of several backup options: a halfhigh tape drive, a DVD-RAM drive, or a GoVault removable disk drive. The tape drive must have a SCSI or USB 2.0 interface. (A SCSI tape drive would require an optional SCSI controller; an internal USB port is provided standard.) The GoVault drive has a SATA interface. No diskette drive is supplied with any model; an external USB floppy drive may be used, if needed. Hot-swap and simple-swap drives may be inserted or removed through the front of the server. Hot-swap drives do not require powering off the system. Simple-swap SATA drives do require powering off the system first; however, no tools or jumpers are required for installation and removal, allowing for faster, simpler servicing than fixed drives. For still more storage, a direct-attach, iSCSI, or SAN external expansion option can be added, using an optional controller. 4 Data transfer rates depend on many factors and are often less than the maximum possible. 4 Please see the Legal Information section for important notices and information.
