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
2-5-inch HDDs not only require less space than 3.5-inch drives, they weigh less, consume half
the power, produce less noise, seek faster, and offer increased reliability.
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.
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%
Two Broadcom 5709S Gigabit Ethernet controllers (one on-board and one on an optional
daughter card) provide four Gigabit ports supporting 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. This controller supports PXE 2.0 remote boot and TOE.
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.
10 Gigabit Ethernet Integrated Virtual Fabric Adapter for IBM
The Emulex Virtual Fabric Adapter for x3650 M3 (part number 49Y4200 with special riser card,
support by CTO) is an industry-leading performance and scalability per watt, dual-port network
adapter for 10Gbps Ethernet (10GbE) networks. It offers the benefits and flexibility of I/O
convergence in a single end-to-end solution. Protocol offload for stateless TCP/IP and TCP
Chimney provide maximum bandwidth with minimum use of CPU resources. It achieves line rate
10Gbps performance with support for TCP/IP stateless offloads and TCP Offload Engine (TOE)
support. TOE reduces system processor utilization, providing increased system performance and
reducing overall system power requirements.
The Emulex 10Gb/s Virtual Fabric Adapter for IBM System x3650 M3 is based on the Emulex
OneConnect Universal Converged Network Adapter (UCNA) platform that also includes the
