assist) standard, and support an optional ServeRAID-BR10il v2, ServerRAID-M1015, ServeRAID-

M5014, or ServeRAID-M5015 SAS/SATA controller, to enhance system performance, availability

and data protection. Hot-swap models include either a ServeRAID-M1015, ServeRAID-M5014, or

ServeRAID-M5015 controller standard (model-specific). They can be upgraded to other ServeRAID

controllers. The supported ServeRAID controllers include:

The 3Gbps

(x4 PCIe) ServeRAID-BR10il v2 controller offers hardware RAID-0/1/1E support (no

cache) for up to 4 HDDs.

The 6Gbps (x8 PCIe) ServeRAID-M1015 SAS/SATA controller supports RAID-0/1/10 (no cache) for

up to 32 drives (limited by available bays to 8). 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 (with optional battery backup), and supports RAID-0/1/10/5/50 for up to 32

drives (limited by available bays to 8).

The 6Gbps (x8 PCIe) ServeRAID-M5015 SAS/SATA controller offers enhanced performance with

512MB of cache memory and battery backup included, and supports RAID-0/1/10/5/50 for up to 32

drives (limited by available bays to 8).

The IBM ServeRAID M5000 Series Advance Feature Key adds RAID-6/60 with SED support to the

ServeRAID-M5014 and M5015. The IBM ServeRAID M5000 Series Battery Key adds battery

backup support to the M5014.

Drive Bays

The x3620 M3 supports up to 9 or 5 drive bays in all (model-specific). Models include either 8 hot-

swap or 4 simple-swap 3.5-inch drive bays, plus one 5.25-inch bay for either an optional optical

drive, a tape drive, or an RDX Removable Disk Backup System. The hot-swap bays support either

SATA or SAS HDDs. The simple-swap bays support only SATA drives.

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 x3620 M3 offers flexibility with either 4 or 8 2.5” HDD bays (model-dependent), supporting high-

performance drives that provide high density/high reliability and allow you to scale up as your

business grows. (Hot-swap models require a RAID controller.)

3.5-inch Hot-Swap SAS

• 15,000 RPMs — 300, 450, or 600GB (4.8TB maximum capacity, with 8 bays)

3.5-inch Hot-Swap SATA

• 7,200 RPMs — 250 or 500GB, 1 or 2TB (16.0TB maximum capacity, with 8 bays)

3.5-inch Simple-Swap SATA

• 7,200 RPMs — 250 or 500GB, 1 or 2TB (8.0TB maximum capacity, with 4 bays)

The hot-swap 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 IBM System

Storage direct-attach, NAS and SAN offerings.

High-Performance Adapter Slots

The x3620 M3 provides three PCIe (PCI Express) Gen 2 I/O slots for long-term investment

protection. PCI Express Gen 2 is the next-generation of high-performance, low-latency, serial I/O

bus. Each slot is capable of supporting Gen 1 or Gen 2 adapters.

• One x16/x8 (x16 physical/x8 electrical) full-height, half-length (8Gbps)

• One x8/x8 (x8 physical/x8 electrical) full-height, half-length (8Gbps)

• One x16/x4 (x16 physical/x4 electrical) low profile (4Gbps) — for ServeRAID cards, only

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