This may result in much higher data transfer rates.
Intelligent Power Capability powers individual processor elements on and off as needed, to
reduce power draw.
Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
DDR II ECC Memory
The x3350 ships with
two DIMMs and supports up to 8GB of memory in 4 DIMM sockets. It uses
PC2-5300 double data rate II (DDR II) memory (operating at 667MHz) for fast access, and ECC
memory protection, for potentially higher system availability than non-ECC memory can provide.
The system requires either
two or four DIMMs and operates in two-way interleaved mode, for
higher performance than noninterleaved mode. Additional memory is available in kits consisting
of two
512MB, 1GB, or 2GB DIMMs.
High-Performance Adapter Slots
The x3350 provides
two x8 (“by 8”) 4GBps PCI-E (PCI Express) adapter slots standard. Each is
capable of supporting physical
x1/x4/x8 adapters at their rated speeds. Both slots are half-
length/full-height.
PCI Express is a high-performance, low-latency, next-generation serial I/O bus that is rapidly
replacing the older parallel PCI and PCI-X buses. A
x8 PCI-E adapter offers approximately four
times the maximum throughput of a 133MHz PCI-X adapter
4
. (A
x1 adapter offers throughput
similar to a
66MHz PCI-X slot.)
Because the
SAS/SATA, dual Gigabit Ethernet, BMC and video controllers are integrated onto
the system board, the two adapter slots are both available, which offers a wide degree of latitude
in expansion options.
Large HDD Storage Capacity
The x3350 offers a choice of disk storage, supporting up to
two (3.5-inch) or four (2.5-inch) hot-
swap high-performance SAS drives, or two (3.5-inch) hot-swap
5
or simple-swap SATA II
drives:
3.5-inch SAS
• 10,000 RPMs —73.4, 146.8 or 300GB (600GB maximum)
• 15,000 RPMs —73.4 or 146.8GB (293.6GB)
2.5-inch SAS
• 10,000 RPMs —73.4 or 146.8GB (587.2GB)
3.5-inch SATA
• 7,200 RPMs —160, 250, 500, or 750GB (1.5TB)
Notes: 2-5-inch drives not only require less space than 3.5-inch drives, they weigh less, consume
half the power, produce less noise, seek faster, and offer increased reliability. Simple-swap SATA
drives are not hot-swappable (the system must first be powered off); however, no tools or
jumpers are required for installation and removal, allowing for faster, simpler servicing than fixed
drives.
The hot-swap SAS drives use the Converged Tray for interchangeability with other IBM
System x
™
systems. If you need more storage space, terabyte capacities are possible with
external direct-attach, NAS and SAN solutions. The x3350 does not support mixing SAS and
SATA drives, or 10K and 15K RPM drives in the same system.
Drive Bays
The x3350 contains either
three or five drive bays in all, depending on the model. Some models
offer
two 3.5-inch bays that support hot-swap SAS or SATA II
6
or
simple-swap SATA II drives.
This enables up to two slimline (1.0") drives to be installed, totaling up to
600GB (SAS) or 1.5TB
(SATA).
Other models feature
four 2.5-inch bays that support hot-swap SAS drives totaling up to
587.2GB.
Hot-swap drives may be inserted or removed through the front of the server without powering off
the system. Simple-swap drives can be inserted or removed through the front of the server
without tools as well; however, the system power must first be turned off.

Actual throughput will depend on the adapter vendor’s implementation.

Hot-swap SATA drives are supported in special bid or CTO systems only.
