Description
xSeries 336 related options
The xSeries 336 server features an Intel Xeon processor
system that supports single-core internal processing
speeds up to 3.8 GHz, or dual-core internal processing
speeds up to 2.8 GHz. Processing operations to memory
and the PCI bus occur at 133 MHz.
integrated, full-speed 2 MB ECC L2 cache per core. This
system supports up to two-socket (four-core) SMP
applications through installation in the second processor
slot of xSeries 336 models with like processors.
High-performance server subsystems: These servers are
high-throughput,
SMP-capable
excellent scalability when you add memory and a second
processor. They incorporate powerful 800 MHz Intel Xeon
processors with 2 MB advanced transfer L2 cache per
core. Data transfer across the system bus is at a 4X rate
(four data transfers per clock) for an effective data
transfer rate of 800 MHz (5.3 GB/s). Address transfers
across the system bus is at a 2x rate (two addresses per
clock) for an effective transfer rate of 400 MHz.
Two Intel Xeon connectors are standard on the system
board to support installation of a second processor.
High-speed 400 MHz PC2-3200 ECC DDR2 SDRAM RDIMM
memory is optimized for 800 MHz processor-to-memory
subsystem performance.
Additional features
System
board
contains
supporting 256, 512 MB, 1 GB, or 2 GB PC2-3200 ECC
DDR2 SDRAM RDIMM memory:
Support for up to 16 GB of system memory
Interleaved memory populated with two DIMM at a
time with the same size DIMM
Support for mixed memory sizes in pairs
Support for Chipkill
Single-channel, 64-bit, Ultra320 SCSI PCI controller
supports high-speed (up to 320 MB/s) data transfer,
and Low-Voltage Differential SCSI (LVDS) internal
storage solutions.
IDE controller supports DVD-ROM.
Support for SATA drive employs high-speed (up to 1.5
Gbps) dual differential pairs to communicate with
simple-swap SATA HDDs.
Two full-duplex Broadcom 5721 Gigabit Ethernet PCI
controllers speed network communications to LAN
clients.
The xSeries 336 subsystems are tuned to provide solid
system throughput from processor, to memory, to bus, to
disk-intensive I/O.
These features combined with SMP
capability make this server an excellent choice for:
Web caching
Dynamic Web serving
Firewall
Telecommunications
Active directory services
Scientific and technical computing
Linux
clustering
