Lenovo 3822, 3821, 3719, 3823 manual Specifications

The server has one slot for a PCI-32 adapter.

vPCI Express x8 adapter capabilities

The server has five slots for PCI Express x8 adapters. Three of these slots accept x8 adapters, but the adapters will operate as x4 adapters.

vPCI Express x16 adapter capabilities

The server has one slot for PCI Express x16 adapter, which will operate as an x8 adapter.

vRedundant cooling and power capabilities

The server supports up to two 920-watt hot-swap power supplies. If the server came with only one power supply, you can install an additional power supply with three redundant hot-swap cooling fans to add redundant power and cooling capabilities. If the maximum load on the server is less than 920 watts and a problem occurs with one of the power supplies, the other power supply can meet the power requirements. The redundant cooling of the fans enables continued operation if one of the fans fails.

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.

vSymmetric multiprocessing (SMP)

The server supports up to two Intel® Xeon® quad-core microprocessors. If the server comes with only one microprocessor, you can install an additional microprocessor to enhance performance and provide SMP capability.

vSystems-management capabilities

The server contains an Integrated Management Module (IMM) which enables you to manage the functions of the server locally and remotely and provides remote presence and blue-screen capture capability. The IMM also provides system monitoring and event recording.

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 running on the server and TOE is enabled, the server supports TOE operation. See the operating-system documentation for information about enabling TOE.

Note: As of the date of this document, the Linux® operating system does not support TOE.
