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. 8Disk ControllersAll x3550 M3 models include a ServeRAID-BR10il v2, ServerRAID-M1015, ServeRAID-M5014or ServeRAID-M5015 SAS/SATA controller standard (model-dependent) to enhance systemavailability and data protection without using a PCI slot.The 3Gbps6 (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 32 drives (limited to available drive bays). The IBM ServeRAID M1000 Series AdvanceFeature Key adds RAID-5/50 with SED support.The 6Gbps (x8 PCIe) ServeRAID-M5014 SAS/SATA controller offers enhanced performancewith 256MB of cache memory, and supports RAID-0/1/10/5/50 for up to 32 drives (limited toavailable drive bays.The 6Gbps (x8 PCIe) ServeRAID-M5015 SAS/SATA controller offers enhanced performancewith 512MB of cache memory and battery backup7, and supports RAID-0/1/10/5/50 for up to 32drives (limited to available drive bays).For external storage, the 6Gbps ServeRAID-M5025 controller enables connection to external IBMSystem Storage expansion units (up to 240 HDDs), as well as support for up to 8 internal HDDs(system limit). It provides RAID-0/1/10/5/50 support, 512MB of onboard cache, and battery backupstandard.The IBM ServeRAID M5000 Series Advance Feature Key adds RAID-6/60 with SED support tothe M5014, M5015, or M5025. The IBM ServeRAID M5000 Series Battery Key adds batterybackup support to the M5014 and CTO systems containing an M5015 or M5025.Drive BaysThe x3550 M3 supports up to 8 drive bays. Base models include 4 2.5-inch drive bays. Optionally,add one 5.25-inch bay for an optional DVD-RW drive, or (using an expansion kit) increase thenumber of 2.5-inch bays to 8, However, these upgrades are mutually exclusive. Upgrading from 42.5-inch drive bays to 8 2.5-inch drive bays would require removal of the 5.25-inch bay, if present.The 2.5-inch bays 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 4 2.5” HDD bays standard and optionally 8 2.5” HDD bays,supporting high-performance drives that provide high density/high reliability and allow you to scaleup as your business grows.2.5-inch Hot-Swap SAS• 7,200 RPMs — 500GB or 1TB8 (4TB maximum capacity with 4 bays / 8TB with 8 bays)• 10,000 RPMs — 73.4, 146.8, 300 or 600GB (2.4TB / 4.8TB)• 15,000 RPMs — 73.4 or 146.8GB (576GB / 1.17TB)2.5-inch Hot-Swap SATA• 7,200 RPMs — 160, 250, or 500GB, or 1TB (4TB / 8TB maximum)• 10,000 RPMs — 300GB (1.2TB / 2.4TB)2-5-inch HDDs not only require less space than 3.5-inch drives, they weigh less, consume half thepower, produce less noise, seek faster, and offer increased reliability.2.5-inch Hot-Swap or Simple-Swap SSDs• 50GB High IOPS (200GB / 400GB maximum) High I/O Performance6 Data transfer rates depend on many factors and are often less than the maximum possible.7 Battery backup is included when the adapter is purchased as an option or when included in standard server models. It is optionalwhen the adapter is included in a CTO system.
