HDD Storage Capacity, High-Performance Adapter Slots

Leadership enterprise server with significantly lower cost of ownership in a highly available and expandable, rack-dense, 1U dual-socket server

The integrated ServeRAID-BR10icontroller offers hardware RAID-0/1/1Esupport. The controller provides data transfer speeds of up to 3Gbps6 per SAS port on an 8-lane 2.5 Gbps PCIe card. It connects to both SAS and SATA SSDs and tape drives.

The x3550 M2 also supports full RAID-0/1/10/1E/5/6support using the optional ServeRAID- MR10i card. It also offers higher performance, due to the 256MB battery-backed onboard cache.

The x3550 M2 also supports hardware based full disk encryption with RAID-0/1/10/1E/5/6support using the optional ServeRAID-MR10is 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

Additional external storage is available.

HDD Storage Capacity

The x3550 M2 offers a flexibility with up to six (6) 2.5” HDD bays; optimal price/performance disk drives that provide ultimate drive density and allow you to scale up as your business grows.

•Support for six300GB hot swap SAS HDD — 1.8TB total internal SAS storage

•Support for six 300GB hot swap SATA HDD — 1.8TB total internal SATA storage (500GB SATA HDD planned 3Q09)

•Support for solid-state drives (SSDs); 32GB or 50GB capacity deployable in all 6 HDD bays

32GB SSD – Slim FF (2.5”) HS HDD (SATA interface) or Simple Swap HDD

50GB SSD – Slim FF (2.5”) High IOPS Hot Swap HDD (SATA Interface) or Simple Swap HDD

•High IO Performance

Up to 8X IOPS more than HDD (67/33% Read/Write OLTP transaction base mix)

Optimized for heavy mix of Read and Write operations such as transaction processing

Media Streaming, Surveillance, File Copy, Logging, Backup/Recovery, Business Intelligence

•Lower Cost IOPS Performance

Yields better $/IOPS: lower capacity (GB) required to achieve higher IOPS

Utilizes Less power and heat than conventional disk drive

•Superior Uptime

3X the availability of mechanical drives with RAID-1

No moving parts to fail

Enterprise wear leveling to extend life even further

•Flexible Deployment with full OS Support

Traditional HDD form factor offerings

Supports Linux, Windows and VMware

2-5-inch drives 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 direct- attach, NAS and SAN solutions.

High-Performance Adapter Slots

The x3550 M2 provides two x16 (“by 16”) 8GBps PCIe (PCI Express) Gen 2 high performance I/O slots help double the performance vs. the previous-generation x3550 for added long-term investment protection. Each is capable of supporting x1/x4/x8 adapters at full speed. One slot is full height, half length. The other is low profile. Each is convertible to one PCI-X/133 MHz using the riser option. High-performance x16 Gen 2 slots are ideal for digital media, 2D graphics environments

PCI Express is a high-performance, low-latency, next-generation serial I/O bus that is rapidly

6Data transfer rates depend on many factors and are often less than the maximum possible.
