Standard Models

X366 with Xeon Dual Core processors

Build your X366 with the Links Below

• Add Memory

• Add Processor

• Add SCSI Drives

• Add RAID card

• Add External storage

• Networking

• Power Supply & RSA II

• Supported Operating Systems

• Upgrade Warranty

The models of the x366 have a 2 GB standard, implemented as two 1 GB PC2-3200 ECC DDR2 DIMMs. Memory is implemented in the x366 using memory cards. Each card has four DIMM sockets. One memory card is standard and the x366 supports up to four memory cards. Using 4 GB DIMMs in every socket (that is, a total of 16 DIMMs), the server can hold 64 GB of RAM.

The memory is two-way interleaved (meaning that memory DIMMs are installed in pairs). (see thumb nail) there are four ports to memory, with each supporting up to 5.33 GBps data transfers. The DIMMs operate at 333 MHz (instead of 400 MHz as for the PC2-3200 spec) so that throughput is 2.67 GBps (333 MHz x 8 bytes). At 2.67 GBps and two-way interleaving, the throughput matches that of the front-side bus at 5.3 GBps so that bus transfers remain in sync.

By adding three additional memory cards (part number 13M7409) and using 4 GB DIMMs (replacing the standard pair of 1 GB DIMMs), the x366 can be expanded to 64 GB.

Because the x366 uses two-way interleaving memory, DIMMs must be installed in matched pairs. Supported DIMM options are

The upgrade options include one processor and one VRM. The VRM must be installed if the option is to be installed as CPU 3 or CPU  The VRMs for CPUs 1 and 2 are integrated onto the processor board. See the x366 Installation Guide for more details.

ServerRaid Options

ServerRAID Options: The x3850 has a disk subsystem that is comprised of an Adaptec AIC-9410 Serial Attached
SCSI (SAS) controller and six internal hot-swap drive bays. The x366 does not support RAID as standard, but the server also supports the addition of the ServeRAID-8i daughter card . Serial Attached SCSI (SAS) is the logical evolution of SCSI. SAS uses much smaller interconnects than SCSI, while offering SCSI compatibility, reliability, performance and manageability. In addition, SAS offers longer cabling distances, smaller form factors and greater addressability.

ServeRAID-8i enables the following RAID levels:
RAID-0,RAID-1, RAID-1E, RAID-5, RAID-5EE, RAID-6,RAID-10

RAID-6 is a multiparity type which requires a minimum of four drives, of which two drives worth of capacity are consumed for redundancy. RAID-6 allows the loss of two drives without data loss, but this loss is associated with a substantial performance degradation.

A note about the two part numbers and firmware: 13N2227 was introduced with the x366 and may have V8.00 or later firmware. 39R8729 was introduced with the x206m and ships with V8.15 or later firmware. 39R8729 will replace 13N2227. The cards are interchangeable, but a ServeRAID-8i installed in the x206m and x306m must have V8.15 firmware or later. A card with firmware earlier than V8.15 will not function in an x206m or x306m. In addition, you cannot upgrade the firmware of the card to V8.15 while it is installed in an x206m or x306m if it has older firmware - you must upgrade the firmware in another system.

39R8729

Support is available for RAID disk arrays, both with the ServeRAID-8i (for internal RAID arrays) and the ServeRAID-6M for external arrays. The x366 has six internal hot-swap disk drive bays.

MFR#

External SCSI Storage

For external SCSI disk enclosures attachment such as the EXP400, the ServeRAID-6M can be installed. Because this card is based on SCSI architecture, it is incompatible with the SAS subsystem and therefore cannot be used to run the internal disks.
