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

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

Drive Bays

The x3400 M2 contains either 11 drive bays (in 2.5-inch models) or 7 bays (in 3.5-inch) models. 2.5-inch
models support small form-factor (SFF) hot-swap SAS drives. 3.5-inch models support four hot-swap
SAS or SATA II drives, or simple-swap SATA II drives. In addition, there are three 5.25-inch bays.
An internal full-high tape drive can be installed using two of the 5.25-inch drive bays; alternatively, an
internal half-high tape drive can be installed using one of the 5.25-inch drive bays. The tape drive must
have a USB 2.0 interface.
A half-high DVD-ROM drive with a SATA interface ships standard in the other 5.25-inch bay. An external
USB floppy drive may be used, if needed.
Hot-swap drives may be inserted or removed through the front of the server without powering off the
system. Simple-swap drives may also be installed and removed through the front, but requires powering
off the server first.
For still more storage, a direct-attach, NAS or SAN external expansion option can be added, using an
optional controller.
Disk/Tape Controllers
All hot-swap x3400 M2 models include an integrated hardware-based IBM ServeRAID-BR10i SAS/SATA
controller. This controller supports up to eight internal SAS or SATA drives. (Simple-swap models use the
SATA support incorporated in the system chipset.)
The integrated ServeRAID-BR10i controller offers hardware RAID-0/1/1E support. The controller provides
data transfer speeds of up to 3Gbps
SAS and SATA HDDs, as well as Solid-State Drives (SSDs) and tape drives.
The x3400 M2 also supports full RAID-0/1/10/1E/5/6 support using the optional ServeRAID-MR10i card. It
also offers higher performance, due to the 256MB battery-backed onboard cache.
The x3400 M2 also supports hardware based full-disk encryption with RAID-0/1/10/1E/5/6 support using
the optional ServeRAID-MR10is Vault card.
For external storage, the 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.
Internal Backup
The x3400 M2 supports several internal tape backup options. Supported technologies include:
• DDS-5 (half-high)
• DDS-6 (half-high)
• GoVault internal dock (half-high)
• LTO-3 Ultrium (half-high)
• LTO-4 Ultrium (half-high)
High-Performance Adapter Slots
The x3400 M2 provides six adapter slots in all, including one x16 ("by 16") physical/x8 electrical PCIe
(PCI Express) Gen 2 full-length/full-height adapter slot (Slot 2). This means that although the slot runs
at x8 Gen 2 speeds (8GBps), it can accept a x16 Gen 2 adapter in the slot. It is also capable of
supporting x1/x4/x8 adapters at full speed. In addition to this slot, the x3400 M2 also includes two x8
physical/x8 electrical Gen 2 slots (8GBps), two x8 physical/x4 electrical Gen 2 slots (4GBps), and one
33MHz legacy PCI slot. As part of a configure-to-order (CTO) build two choices of PCIe riser card can be
added, with either two 133MHz PCI-X slots or one PCIe x8 physical/x4 electrical Gen 1 slot (2GBps).
Slot 1 is a half-length/full-height PCIe slot; slots 2, 3, 4 and 5 are full-length/full-height PCIe slots,
and Slot 6 is a half-length/full-height 33MHz legacy PCI slot. The PCI-X riser contains two full-
length/full-height slots (5 and 6).
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 x16 PCIe Gen 2 adapter offers approximately sixteeen times
the maximum throughput of a 133MHz PCI-X adapter
66MHz PCI-X slot.)
Dual-Port Gigabit Ethernet Controller
The x3400 M2 includes one dual-port integrated Broadcom 5709C Gigabit Ethernet controller for up to
10X higher maximum throughput than a 10/100 Ethernet controller, as well as support for PXE 2.0
