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
.
(
Note:
The use of the internal backup drive option precludes the use of two drive bays, limiting
storage to four 3.5-inch HDDs.)
The 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.
Disk/Tape Controllers
All x3650 models include an integrated eight-port
Adaptec AIC9580W
Serial-Attach SCSI
(SAS)
controller. This controller supports up to
six
or
eight
(depending on the model) internal
SAS LVD (low-voltage differential) drives, plus external storage via the SAS port on the rear of
the server.
The integrated
ServeRAID-8k-l
controller offers
hardware
RAID-0
/
1/10
support and
32MB
of
fast
PC2-4200
DDR2
cache for those SAS drives. The
ServeRAID-8k
option adds
three
additional RAID levels, including
RAID-1E, 5
and
6
, along with
256MB
of cache memory for
higher performance, and battery backup,
without
consuming a valuable adapter slot.
The
SAS
controller provides data transfer speeds of up to
300MB
per second
5
in
each
direction
(
full-duplex
) across the SAS bus, 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.
Other supported RAID controllers include:
•
ServeRAID-6M
—
Ultra320
, 2-channel,
256MB
battery-backed cache, 133MHz PCI-X (2
ports for external SCSI RAID storage)
•
ServeRAID-6M
—
Ultra320
, 2-channel,
128MB
battery-backed cache, 133MHz PCI-X (2
ports for external SCSI RAID storage)
The
ServeRAID-6M
controllers support external SCSI expansion via the
IBM EXP400
Storage
Expansion Unit.
For external storage, the
MegaRAID 8480
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
support and
256MB
of onboard cache. Additional external SAS/SATA storage is available using
the
external SAS port
on the system unit, or via one of several supported iSCSI or SAN
controllers.
Drive Bays
The x3650 contains
either
seven
or
ten
drive bays in all, depending on the model. Some
models offer
six
3.5-inch
bays that support
hot-swap SAS
or
SATA
drives. This enables up to
six slimline (1.0") drives totaling up to
1.8TB
(SAS) or
6TB
(SATA) to be installed.
An internal
half-high
DDS5
tape drive or
GoVault
EZ Drive
can be installed
in place of
two
of
the HDDs. This offers the confidence of internal tape backup, while still leaving
four
available
drive bays (for a total disk capacity of up to
1.2TB
of
SAS
or
4TB
of
SATA
storage,
respectively).
Other models feature
eight 2.5-inch
bays that support
hot-swap SAS
drives totaling up to
1.17TB
. In
addition
to the eight 2.5" HDD bays, there is a
dedicated bay
for a
half-high
DDS5
tape drive or
GoVault
EZ
drive.
A
24X/10X/24X/8X
6
speed (ultraslim, 0.5”) CD-RW/DVD-ROM combo drive with an IDE
interface ships standard in all x3650 servers. No floppy drive is supplied with any model; an
external USB floppy drive may be used, if needed.
For still more storage, a direct-attach, iSCSI, or FC SAN external expansion option can be
added, using an optional controller.
Backup Devices
The x3650 supports several internal and external backup
options. Supported drives include:
•
36/72 GB DDS-5 Tape Drive
(SCSI)
•
80/120 GB GoVault EZ Drive
(SATA)
•
80/160 GB Half High VS160 Tape Drive
(SCSI)
•
400/800 GB LTO-3 Ultrium Tape Drive
(external SCSI)

Data transfer rates depend on many factors and are often less than the maximum possible.
6
Variable read rate. Actual playback speed varies and is often less than the maximum possible.
