The following figure shows the ThinkServer sd350 server.

Figure 1. The ThinkServer sd350 server

The sd350 supports two Intel Xeon E5-2600 v4 processors, each with up to 20 cores and a 135W TDP rating. This means you can fit 160 cores in 2U of rack space.

These servers are also fully managed systems with IPMI 2.0 support for remote management via a dedicated RJ45 port, xCAT support, planned Lenovo XClarity support,and an AMI BIOS and BMC code stack.

The ThinkServer sd350 dense offering fits four hot-pluggable sd350 servers into an n400 enclosure that takes up only 2U (0.5U per server) and includes room for plenty of internal storage. The overall design makes the solution extremely affordable, with a low total cost of ownership (TCO).

The n400 is a 2U enclosure that holds four servers at the back and 24x 2.5-inch hot-swap drives at the front. Six drive bays are connected to each server; the drives are not shared between the servers. The rear of the server houses the four sd350 servers and two power supplies. The power supplies provide power to the servers and the drives.

In the sd350, the maximum memory speed of a configuration is the lower of the following two values:

• The memory speed of the processor
• The memory speed of the DIMM

The following table shows the maximum memory speeds that are achievable. The table also shows the maximum memory capacity at any speed that is supported by the DIMM and the maximum memory capacity at the rated DIMM speed.

In the table, cells that are highlighted in gray indicate when the specific combination of DIMM voltage and number of DIMMs per channel still allows the DIMMs to operate at the rated speed.

* The maximum quantity that is supported is shown for two processors that are installed. When one processor is installed, the maximum quantity that is supported is half of that shown.

The following memory protection technologies are supported:

• ECC
• Memory mirroring
• Memory sparing
• Memory scrubbing

If memory mirroring is used, DIMMs must be installed in pairs (minimum of one pair per CPU), and both DIMMs in a pair must be identical in type and size.

If memory rank sparing is used, a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need to be identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs that are installed.

Each sd350 is connected to six 2.5-inch hot-swap drive bays. The 24 drive bays (six for each server) are physically located at the front of the n400 enclosure and are routed to each server via SAS/SATA cables connected to the drive backplane.

SATADOM options are listed in the Internal drive options section.

For configurations where not all drive bays are filled with drives, sufficient fillers should be installed to fill all empty drive bays to ensure proper cooling. From the factory, either single-bay or four-bay fillers are used. For example, if no drives are configured, then one four-bay and two single-bay fillers are used.

As you add a drive, you remove the filler bay and replace it with a drive. A special case is if only two drives are installed in the factory. In such a configuration, the remaining four bays have a single four-bay filler inserted. If you wish to add a third drive, you will need to remove the four-bay filler and install the drive. The remaining three bays must be installed with three single-bay fillers which will need to be ordered separately. Ordering information for the single-drive filler is in the following table.

The onboard SATA controller in the sd350 (integrated into the Intel C612 chipset) implements Intel Rapid Storage Technology enterprise (RSTe) and supports SATA drives installed in the 6 drive bays. The onboard controller supports a minimum of 1 drive and a maximum of 6 drives.

All ports of the OCP Network Adapter have NC-SI enabled and support both remote management functions as well as standard operating system network functions.

The server has an integrated ThinkServer Management Module (TMM) baseboard management controller (BMC) for configuration, systems management, and remote control.

The remote presence (remote KVM & media) and blue-screen capture features are standard functions of the TMM. The remote presence feature provides the following functions:

• Remotely viewing video with graphics resolutions up to 1024 x 768, regardless of the system state
• Remotely accessing the server, using the keyboard and mouse from a remote client
• Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server
• Uploading a diskette image to the TMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the TMM restarts the server when the TMM detects an operating-system hang condition. A system administrator can use the blue-screen capture feature to assist in determining the cause of the hang condition.

The sd350 also supports IPMI 2.0 for out-of-band management. Management can be done through the dedicated RJ45 systems management port or through port 1 of the OCP network card installed in the server. The latter connection is shared with the operating system.

Supported interfaces include:

• Command-line interface (IPMI Shell)

  The command-line interface provides direct access to server management functions through the IPMI 2.0 protocol. Use the command-line interface to issue commands to control the server power, view system information, and identify the server. You can also save one or more commands as a text file and run the file as a script.

• Serial over LAN

  Establish a Serial over LAN (SOL) connection to manage servers from a remote location. You can remotely view and change the UEFI settings, restart the server, identify the server, and perform other management functions. Any standard Telnet client application can access the SOL connection.

The sd350 is also supported with Lenovo XClarity Administrator. Lenovo XClarity Administrator is a centralized resource management solution designed to reduce complexity, speed response, and enhance the availability of Lenovo systems and solutions.

Lenovo XClarity Administrator provides agent-free hardware management for ThinkServer, System x, and Flex System servers. The administration dashboard, shown in the following figure, is based on HTML 5 and allows fast location of resources, so tasks can be run quickly.

Figure 11. Lenovo XClarity Administrator dashboard

Because Lenovo XClarity Administrator does not require any agent software to be installed on the managed endpoints, there are no CPU cycles spent on agent execution and no memory is used. This means that up to 1GB of RAM and 1 - 2% CPU usage is saved, compared to a typical managed system where an agent is required.

Lenovo XClarity Administrator supports the following functions with the ThinkServer sd350:

• Discovery
• Inventory
• Monitoring and alerting
• Call home

Functions that are not currently supported are:

• Centralized user management
• Cryptography modes, server certificates, and encapsulation
• Configuration patterns
• Operating system deployment
• Firmware updates
• Rack view for tower-based servers
