updated/patched much like firmware. Licensing works the same as for “standard” ESX.
Disk Controllers
All x3650 M3 models include a ServeRAID-BR10il v2, ServerRAID-M1015, ServeRAID-M5014,
or ServeRAID-M5015 SAS/SATA controller standard (model-dependent) to enhance system
availability and data protection without using a PCI slot.
The 3Gbps 6 (x4 PCIe) ServeRAID-BR10il v2 controller offers hardware RAID-0/1/1E support (no
cache) for up to 4 HDDs or SSDs.
The 6Gbps (x8 PCIe) ServeRAID-M1015 SAS/SATA controller supports RAID-0/1/10 (no cache)
for up to 16 drives. The IBM ServeRAID M1000 Series Advance Feature Key adds RAID-5 with
SED support.
The 6Gbps (x8 PCIe) ServeRAID-M5014 SAS/SATA controller offers enhanced performance
with 256MB of cache memory, and supports RAID-0/1/10/5/50 for up to 16 drives.
The 6Gbps (x8 PCIe) ServeRAID-M5015 SAS/SATA controller offers enhanced performance
with 512MB of cache memory and battery backup, and supports RAID-0/1/10/5/50 for up to 16
drives.
The IBM ServeRAID M5000 Series Advance Feature Key adds RAID-6/60 with SED support to
the M5014 and M5015. The IBM ServeRAID M5000 Series Battery Key adds battery backup
support to the M5014.
For external storage, the 3Gbps ServeRAID-MR10M 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.
Drive Bays
The x3650 M3 supports up to 17 drive bays in all. Base models include 4 2.5-inch drive bays,
expandable to 16, using expansion kits, and one 5.25-inch bay for an optional DVD-RW drive.
The bays support a combination of SATA and SAS HDDs, as well as solid-state drives (SSDs)
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 as
well; however, the system power must first be turned off.
For additional storage, a direct-attach, NAS or SAN external expansion option can be added,
using an optional controller.
No diskette drive is supplied with any model; an external USB floppy drive may be used, if
needed.
Flexible Internal Storage
The x3650 M3 offers flexibility with up to 16 2.5” HDD bays, supporting high-performance drives
that provide high density/high reliability and allow you to scale up as your business grows.
2.5-inch Hot-Swap SAS
• 7,200 RPMs — 500GB (8.0TB maximum capacity, with 16 bays)
• 10,000 RPMs — 73.4, 146.8, or 300GB (4.8TB maximum)
• 15,000 RPMs — 73.4 or 146.8GB (2.35TB maximum)
2.5-inch Hot-Swap SATA
• 7,200 RPMs — 160 or 500GB (8.0TB maximum)
• 10,000 RPMs — 300GB (4.8TB maximum)
2.5-inch Hot-Swap or Simple-Swap SSDs
• 50GB High IOPS (800GB maximum)
High I/O Performance
– Offers up to 8X more IOPS than HDDs (67/33% read/write OLTP transaction base mix)
– Optimized for heavy mix of read and write operations, such as transaction processing,
media streaming, surveillance, file copy, logging, backup/recovery, and business
Intelligence
Lower-Cost IOPS Performance
– Yields better $/IOPS: lower capacity (GB) required to achieve higher IOPS
– Uses less energy and generates less heat than a hard disk drive
6 Data transfer rates depend on many factors and are often less than the maximum possible.
