The Bottom Line
The IBM System x3550 M3 is an extremely energy efficient, powerful system, incorporating
significantly redesigned management tools and abundant IBM-unique innovations:
Price/Performance
• High-throughput processors — Up to two 2.66 to 3.33GHz 6-core, 2. 40GHz to 3.46GHz
4-core, or 1.86GHz to 2.13GHz low-voltage 4-core, or 2.26GHz low-voltage 6-core Xeon
5600 Series processors; or two 2.0GHz to 2.93GHz 4-core or 2.0GHz 2-core Xeon 5500
Series processors
• Energy-efficient low-voltage processors — 40W 4-core and 60W 6-core Xeon 5600
Series processors
• Hyper Threading Technology for up to 12 processor cores and 24 threads total
(processor-specific)
• Turbo Boost Technology for a performance boost when not all cores are in use
(processor-specific)
• 64-bit extensions (EM64T)
• Large cache — 12MB or 4MB of L3 processor cache (processor-specific)
• Fast memory — Registered PC3-10600 DDR III ECC DIMMs standard, operating at
1333MHz, 1066MHz or 800Mhz (depending on processor model and memory
configuration); supports 2 DIMMs per channel at 1333MHz
• Fast disk technology — Supports high-performance SAS drives that provide high
density/high reliability and allow you to scale up as your business grows.
• High IOPS SSDs — Solid-state drives offer significantly higher I/O operations per second
than HDDs
• Fast communications — Integrated dual Gigabit Ethernet controllers standard supporting
load-balancing and failover; two additional NICs optional
• Fast I/O — Two PCIe x16 adapter slots (replaceable with two PCI-X/133 slots)
Flexibility
• Large memory capacity — Up to 192GB of registered DDR2 DIMMs, in 18 DIMM slots
• Up to 8 2.5-inch hot-swap SAS/SATA HDDs or SSDs or simple-swap SSDs
• Choice of disk storage — Up to 4.0TB of internal SAS/SATA storage, 800GB of internal
solid-state storage
• High-performance external expansion — Five 480Mbps USB 2.0 ports (two front, two
rear, one internal for an optional USB key with hypervisor)
• Slotless hardware-based 3Gbps RAID-0/1/1E,or 6Gbps RAID-0/1/10 or RAID-0/1/10/5/50
standard
• Two available adapter slots —
Two x16
8
PCIe slots (Gen2)
An optional riser card containing one 133MHz PCI-X slot can replace the riser card
containing each of the PCIe slots
• Optional DVD-RW drive
• Two video ports (one on the front and one on the back)
Manageability, Serviceability and Availability
• IBM Systems
Director systems management software, including (among others:
IBM Systems Director Active Energy Manager
IBM Service and Support Manager
• Integrated Management Module (IMM):
IPMI 2.0 compliance, including highly secure remote power control
Text console redirection systems management standard
• Active Memory protection:
Advanced Chipkill ECC memory protection support
Memory mirroring
• Integrated slotless ServeRAID controller — enhances system availability and serviceability
without using a PCIe slot
• A combination of hot-swap SAS/SATA HDDsor SSDs, or simple-swap SSDs—for quicker
servicing than with fixed drives
