of needs. PCI Express Gen 2 is the latest high-performance, low-latency, next-generation serial
I/O bus. One x16 physical/x16 electrical (“by 16”) 16GBps full-length/full-height slot (Slot 1)
supports x1/x4/x8/x16 Gen 1 or Gen 2 cards at full rated throughput. Two x8 physical/x8
electrical 8GBps half-length/full-height slots (Slots 2 and 3) support x1/x4/x8 Gen 1 or Gen 2
cards at full rated throughput. One x8 physical/x4 electrical 4GBps half-length/full-height slot
(Slot 4) support x1, x4, and x8 Gen 1 or Gen 2 cards, but at a maximum of x4 Gen 2 throughput.
Slot 4 is reserved for the RAID controller.
Drive Bays
The x3755 M3 contains nine drive bays in all (one 5.25-inch and eight 3.5-inch). All models
support hot-swap SAS/SATA drives. This enables up to eight SAS or SATA drives to be
installed. A simple-swap SATA option is available via CTO only, supporting up to six drives.
The fifth drive bay supports an optional 5.25-inch optical drive with a SATA interface. No floppy
drive is supplied with any model; an external USB floppy drive may be used, if needed.
Large HDD Storage Capacity
The x3755 M3 offers a choice of disk storage, supporting up to eight 3.5-inch hot-swap SAS or
SATA, or six 3.5” simple-swap drives:
3.5-inch Hot-Swap SAS
• 15,000 RPMs — 300,450GB, 600GB (4.8TB)
• 7,200 RPMs – 1 or 2TB (16TB)
3.5-inch Hot-Swap SATA
• 7,200 RPMs — 250 or 500GB, 1 or 2TB (16TB)
3.5-inch Simple-Swap SATA
• 7,200 RPMs – 250 or 500GB, 2TB (12TB)
Disk and Tape Controllers
All models include an integrated IBM ServeRAID-M1015 or ServeRAID-M5015 SAS/SATA
Controller (model-specific) in a dedicated PCIe slot. Supported controllers include:
• The 6Gbps (x8 PCIe) ServeRAID-M1015 SAS/SATA controller — RAID-0/1/10 (no cache)
for up to 8 drives. The IBM ServeRAID M1000 Series Advance Feature Key adds RAID-5
support.
• The 6Gbps (x8 PCIe) ServeRAID-M5014 SAS/SATA controller — enhanced performance
with 256MB of cache memory, and supports optional RAID-0/1/10/5/50 for up to 8 drives
and self-encrypting drives (SED).
• The 6Gbps (x8 PCIe) ServeRAID-M5015 SAS/SATA controller — enhanced performance
with 512MB of cache memory and battery backup, and supports RAID-0/1/10/5/50 for up to
8 drives.
• The ServeRAID M5000 Series Advance Feature Key adds RAID-6/60 with SED support to
the M5014 and M5015. The ServeRAID M5000 Series Battery Key adds battery backup
support to the M5014.
• 6Gbps SAS HBA controller for SAS tape drive support
Removable Storage
All models support internal or external removable storage. Supported drives include:
• DDS Gen 5 (internal SATA)—for simple-swap systems only
• DDS Gen 6 (internal USB)
• RDX Removable Disk Cartridge (external USB )
• RDX Removable Disk Cartridge (internal SATA via CTO only)
Dual Gigabit Ethernet Controllers
The x3755 M3 includes two dual-port integrated Broadcom BCM5709C Gigabit Ethernet
controllers with TOE, and RDMA support, as well as load-balancing and failover capabilities,
with up to 10X higher maximum throughput than a 10/100 Ethernet controller.
It also supports 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.
