Leadership enterprise server with significantly lower cost of ownership in a highly available andexpandable, rack-dense, 1U dual-socket serverPlease see the Legal Information section for important notices and information. 8Drive BaysThe x3550 M3 supports up to 8 drive bays. Base models include 4 2.5-inch drive bays and one5.25-inch bay, for an optional DVD-RW drive. Using an expansion kit, the number of 2.5-inchbays can be increased to 8; however, this requires the removal of the 5.25-inch bay. The 2.5-inchbays support a combination of SATA and SAS HDDs, as well as solid-state drives (SSDs)Hot-swap drives may be inserted or removed through the front of the server without powering offthe system. Simple-swap solid-state drives can be inserted or removed through the front of theserver as well; however, the system power must first be turned off.For additional storage, a direct-attach, NAS or SAN external expansion option can be added,using an optional controller.No diskette drive is supplied with any model; an external USB floppy drive may be used, ifneeded.Flexible Internal StorageThe x3550 M3 offers flexibility with up to 8 2.5” HDD bays, supporting high-performance drivesthat provide high density/high reliability and allow you to scale up as your business grows.2.5-inch Hot-Swap SAS• 7,200 RPMs — 500GB (8.0TB maximum capacity, with 8 bays)• 10,000 RPMs — 73.4, 146.8, or 300GB (2.4TB maximum)• 15,000 RPMs — 73.4 or 146.8GB (1.17TB maximum)2.5-inch Hot-Swap SATA• 7,200 RPMs — 160 or 500GB (4.0TB maximum)• 10,000 RPMs — 300GB (2.4TB maximum)2.5-inch Hot-Swap or Simple-Swap SSDs• 50GB High IOPS (400GB maximum) High I/O Performance– Offers up to 8X more IOPS than HDDs (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, and businessIntelligence 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 OSes2-5-inch HDDs not only require less space than 3.5-inch drives, they weigh less, consume halfthe power, produce less noise, seek faster, and offer increased reliability.The hot-swap SAS drives use the Converged Tray for interchangeability with other IBM Systemx® systems. If you need more storage space, terabyte capacities are possible with external IBMSystem Storage direct-attach, NAS and SAN offerings.Disk ControllersAll x3550 M3 models include a ServeRAID-BR10il v2, ServerRAID-M1015, or ServeRAID-M5014 SAS/SATA controller standard (model-dependent) to enhance system availability anddata protection without using a PCI slot.The 3Gbps5 (x4 PCIe) ServeRAID-BR10il v2 controller offers hardware RAID-0/1/1E support (nocache) for up to 4 HDDs or SSDs.The 6Gbps (x8 PCIe) ServeRAID-M1015 SAS/SATA controller supports RAID-0/1/10 (no cache)for up to 8 drives. The IBM ServeRAID M1000 Series Advance Feature Key adds RAID-5 with5 Data transfer rates depend on many factors and are often less than the maximum possible.
