For additional storage, a direct-attach, iSCSI or FC SAN external expansion option can be added,
using an optional controller.

CD-RW/DVD-ROM Combo drive with an
IDE interface ships standard in all x3350 servers. No diskette drive is supplied; an external USB
floppy drive may be used, if needed.
Disk Controllers
All
hot-swap x3350 models include an integrated LSI 1064E Serial-Attach SCSI (SAS)
controller. This controller supports up to
four internal 2.5-inch SAS LVD (low-voltage differential)
drives, or
two 3.5-inch SAS or SATA drives. Simple-swap SATA models have a separate
controller, which supports up to
two internal SATA drives. (The LSI RAID controller is available
as an option for the simple-swap models.)
The integrated LSI
RAID controller offers hardware RAID-0/1 support for the hot-swap drives,
without consuming a valuable adapter slot. The controller provides data transfer speeds of up to
300MB per second (3Gbps)
8
in each direction (
full-duplex) to 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.
SATA II drives also operate at a data transfer speed of up to 300MB per second (but in half-
duplex mode). The SATA 3Gbps controller integrated in the simple-swap SATA models
supports up to
two internal SATA II drives, with maximum data transfer rates of up to 300MB
(
half-duplex) per second. This is throughput is similar to that of Ultra320 SCSI.
The optional
ServeRAID-MR10i full-height/half-length PCI-E x8 controller supports up to four
internal SAS or SATA HDDs. It provides
RAID-0/1/10/5/6
9
support and
256MB ofoptional
onboard
write-back cache(with battery backup).
For external storage, the
ServeRAID-MR10M PCI-E x8 controller enables connection to up to
four IBM System Storage EXP3000 SAS expansion units (48 HDDs total). It provides RAID-
0/1/10/5/50/6/60 support and 256MB of onboard cache.
Additional external SAS/SATA storage is available using the optional
IBM HBA SAS controller, or
one of several supported iSCSI or FC SAN HBAs.
Dual Gigabit Ethernet Controllers
The x3350 includes
two integrated Broadcom 5722 Gigabit Ethernet controllers for up to 10X
higher maximum throughput than a 10/100 Ethernet controller. Both support
load balancing and
failover.
Both controllers support highly secure remote power management using
IPMI 2.0, plus Wake on
LAN
®
and
PXE (Preboot Execution Environment) flash interface. Optional PCI adapters offering
failover and load balancing between adapters are available for added throughput and increased
system availability.
Hot-Swap/Redundant Components
System availability is maximized through the extensive use of hot-swap and redundant
components, including:
• Hot-swap, redundant hard disk drives (with RAID-1/10 protection standard and four other
RAID levels optional)
• Hot-swap, redundant power supplies (optional)
• Hot-swap, redundant cooling fans (standard)
Light Path Diagnostics
Light path diagnostics enables a technician to quickly identify and locate a failed or failing system
component, such as a specific fan or memory DIMM. This enables quick replacement of the
component, which helps increase server uptime and lower operating costs.
The front of the server has an LED indicator light to show possible component failures. If the front
LED indicates an error condition, by pressing a button on the front of the server an LED panel will
pop out and drop down for easy viewing without the need to open the server cover or remove the
server from the rack. The light path diagnostics panel tells the servicer which component requires
attention. In addition, many components have their own identifying LEDs. For example, each of
the memory modules has an LED next to the socket, as does the processor, both adapter slots,

Variable read rate. Actual playback speed varies and is often less than the maximum possible.

Data transfer rates depend on many factors and are often less than the maximum possible.

RAID-5 and RAID-6 require three or four HDD, respectively; therefore they are available only on models with 2.5-inch HDDs.
