Lenovo 3797 Integrated network support, Large data-storage and hot-swap capability, RAID support

The ThinkServer EasyManage program helps you manage and administer your servers and clients through remote problem notification as well as monitoring and alerting.

vIntegrated network support

The server comes with two integrated Broadcom Gigabit Ethernet controllers, which support connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network. For more information, see “Configuring the Gigabit Ethernet controller” on page 118.

vLarge data-storage and hot-swap capability

The server supports up to eight or twelve 2.5-inch hot-swap hard disk drives in the hot-swap bays (depending on the model and optional devices installed). With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.

vEasyLED diagnostics

EasyLED diagnostics provides LEDs to help you diagnose problems. For more information, see “EasyLED diagnostics panel” on page 16

vMemory mirroring

Memory mirroring improves the availability of memory by writing information to the main memory and redundant locations in a mirrored pair of DIMMs.

vLarge system-memory capacity

The memory bus supports up to 128 GB of system memory. The memory controller supports error correcting code (ECC) for up to 16 industry-standard PC3-10600R-999 (single-rank or dual-rank), 800, 1067, and 1333 MHz, DDR3 (third-generation double-data-rate), registered, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs).

vPCI adapter capabilities

The server supports up to four PCI interface slots. For more information, see “Installing a PCI adapter” on page 56.

vRedundant connection

The addition of the optional Ethernet daughter card provides failover capability to a redundant Ethernet connection with the applicable application installed. If a problem occurs with the primary Ethernet connection and the optional Ethernet daughter card is installed on the server, all Ethernet traffic that is associated with the primary connection is automatically switched to the optional redundant Ethernet daughter card connection. 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 three hot-swap fans, which provide redundant cooling. Redundant cooling enables continued operation if one of the fans fails. The server supports up to two 675-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 675 watts and a problem occurs with one of the power supplies, the other power supply can meet the power requirements.

vRAID support

The server supports an internal RAID 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.

vTCP/IP offload engine (TOE) support

The Ethernet controllers in the server support TOE, which is a technology that offloads the TCP/IP flow from the microprocessors and I/O subsystem to increase the speed of the TCP/IP flow. When an operating system that supports TOE is
