vEasy LED Diagnostics
Easy LED Diagnostics provides LEDs to help you diagnose problems. For more information, see the section about Easy LED Diagnostics in the Hardware Maintenance Manual.
vMemory mirroring
Memory mirroring improves the reliability of memory by writing information to the main memory and redundant locations in a mirrored pair of DIMMs.
vOnline-spare memory
Online-spare memory disables a failed pair of DIMMs from the system configuration and activates an online-spare DIMM pair to replace the failed pair.
vPCI Express adapter capabilities
The server has two slots for low-profile PCI Express x4 adapters. These slots accept x8 adapters, but the adapters will operate as x4 adapters. The server also has two slots for PCI Express x8 adapters (on the riser card, full-height, one full-length and one half-length).
Note: You can replace these PCI Express x8 slots with PCI-X 133 MHz slots by replacing the PCI Express riser-card assembly with an optional PCI-X riser-card assembly.
vRedundant connection
The addition of an optional network interface card (NIC) provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated with the primary connection is automatically switched to the redundant NIC. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.
vRedundant cooling and power capabilities
The server supports up to 10 hot-swap fans, in multiples of 5, which provide redundant cooling. Redundant cooling enables continued operation if one of the fans fails. The server supports up to two 835-watt ac power supplies, which provide redundancy and hot-swap capability for a typical configuration. If the maximum load on the server is less than 835 watts and a problem occurs with one of the power supplies, the other power supply can meet the power requirements.
Note: A 700-watt-48 volt dc power supply option may be available. The dc power supplies provide redundancy but no hot-swap capability.
vRAID support
The server supports an internal ServeRAID-8k or 8k-l SAS Controller, which is required for you to use the hot-swap hard disk drives and to create redundant array of independent disks (RAID) configurations.
