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
Superior Uptime
– 3X the availability of mechanical disk drives
– No moving parts to fail
– Enterprise wear-leveling to extend life even further
Full OS Support
– Supports all ServerProven OSes
The hot-swap SAS 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.
Internal Backup
The x3650 M3, using the optional Tape Enablement Kit, supports several internal backup
options. Supported technologies include:
• DDS-5 (half-high)
• DDS-6 (half-high)
• RDX Removable Disk Cartridge (half-high)
High-Performance Adapter Slots
The x3650 M3 provides four x8 ("by 8") 8GBps 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 x1/x4/x8 Gen 1 or Gen 2 adapters at full
speed. (2 PCI x16 Gen 2 or PCI-X/133 slots are optional via replacement riser cards.)
• Four PCIe Gen 2 slots are available:
Two x8-full-height, full-length
One x8 full height, half-length
One x8 low profile
There is also a dedicated riser card in the x3650 M3 that provides a x8 PCIe connector wired with
x4 lanes for an internal ServeRAID card.
Dual-Port Gigabit Ethernet Controller
The x3650 M3 includes one dual-port integrated Broadcom 5709S Gigabit Ethernet controller
standard, for up to 10X higher maximum throughput than a 10/100 Ethernet controller, as well as
support for TOE (TCP Offload Engine), as well as load-balancing and failover capabilities
between the two ports.
TOE helps improve overall system performance by offloading TCP/IP protocol processing from the
system microprocessor to the onboard Ethernet TOE processor.
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.
Integrated quad Gb Ethernet ports:
• Up to four Gb Ethernet ports, ideal for virtualization and I/O-intensive workloads
• 2 ports standard, plus two additional ports via optional daughtercard
• Improves system performance by offloading protocol processing from CPU to a separate TOE
engine
• Primary performance improvement for data copying (CPU) where CPU utilization is 90-100%
The 5709S controller supports IEEE 802.3 for 1000Base-T, 100Base-TX, and 10Base-T
applications (802.3, 802.3u, 802.3ab) through a RJ-45 connector to an Ethernet network over a
CAT 5 twisted-pair cable. TOE support on Windows is available today, but requires the Windows
Scalable Network Pack (SNP) installed. Linux has no plan to support TOE at this time.
