- Powerful Intel® quad- and six-core processors
- New energy-efficient design incorporating 460 W and 675 W high-efficiency power supplies, six cooling fans (three banks of counter-rotating dual fans), altimeter (barometric pressure sensor), and energy-efficient planar components to help lower operational costs
- Highly functional chipset optimized for better application computing for general business workloads
- Eighteen DIMM slots that enable you to deploy up to 192 GB of DDR3 SDRAM Registered DIMM memory, with 4 GB memory standard, or support up to 48 GB of DDR3 SDRAM Unbuffered DIMM memory via 12 DIMM slots
- Standard SAS/SATA HDDs or SSDs with RAID support on hot-swap models
- Support for up to sixteen hot-swap SAS/SATA HDDs or SSDs
- Integrated Dual Gigabit Ethernet ports (standard) for high I/O capacity, and two additional GbE ports (optional) with failover capability
- Support for Embedded VMware ESXi 4.1 hypervisor (connector on an internal SAS riser card activated with optional 2 GB USB key)
- Four PCI-Express x8 high-performance Gen 2 I/O slots that help provide greater network performance with long-term investment protection (four PCIe x8 convertible to two x16 PCIe or four PCI-X 64-bit slots)
- NEBS 1/ETSI equivalent compliance for both ac and dc power supply (model dependent)
- Compliance with 80PLUS and ENERGY STAR standards (model dependent)

Manage with efficiency
High availability, manageability, and serviceability features help diagnose problems quickly, even from remote locations:

- IBM Systems Director Active Energy Manager™ for advanced datacenter power notification and management to help achieve lower heat output and reduced cooling needs
- Snoop filters to boost processor performance
- Integrated SAS controller supporting up to sixteen 2.5-inch hot-swap HDD bays (four or eight bays standard, four-bay kits that upgrade from four to eight bays or eight-bay kits that upgrade from eight to sixteen bays optional) with five RAID alternatives, helping to safeguard your data with either the standard RAID controller at no additional cost or an optional RAID controller for enhanced support.
- Memory mirroring, configurable using Unified Extensible Firmware Interface (UEFI) setup
- Integrated Management Module (IMM) systems management processor
- Monitoring and control of operating status and key server components
- Predictive Failure Analysis® (PFA) on selected components that warns of problems before they occur
- Fast and easy servicing through innovative light path diagnostics, improved onboard diagnostics, and LED diagnostic panel

Ultimate fault tolerant protection
- Hot-swap, redundant fans with calibrated vectored cooling to keep components cool, and simplified fan replacement
- Optional hot-swap, redundant power supplies to help reduce down time
- IBM Director and web support
- Three-year, Customer Replaceable Unit (CRU) and on-site labor1, limited warranty2; optional warranty service upgrades available
