Did you know?

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.

Key features

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.

Scalability and performance

The sd350 server and n400 enclosure offer numerous features to boost performance, improve scalability, and reduce costs:

  • Up to four nodes in a single 2U enclosure, each with two of the latest Xeon v4 processors, 16 DIMMs, and three PCIe slots. It is a highly dense, scalable, and price-optimized offering.
  • The Intel Xeon processor E5-2600 v4 product family improves productivity by offering superior system performance, with 20-core processors, core speeds up to 2.6 GHz, L3 cache sizes up to 50 MB, DDR4 memory speeds up to 2400 MHz, and QPI interconnect links of up to 9.6 GTps.
  • Two processors in each server, up to 40 cores total and 88 threads maximize the concurrent execution of multithreaded applications. With four nodes in the n400 enclosure, a total of 160 cores are available.
  • Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows CPU cores to run at maximum speeds during peak workloads by temporarily going beyond processor thermal design power (TDP).
  • Intel Hyper-Threading Technology boosts performance for multithreaded applications by enabling simultaneous multithreading within each processor core, up to two threads per core.
  • Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating system vendors to better use the hardware for virtualization workloads.
  • Intel Advanced Vector Extensions 2 (AVX2) improve floating-point performance for compute-intensive technical and scientific applications.
  • Sixteen DIMMs of registered 2400 MHz DDR4 ECC memory provide speed, high availability, and a memory capacity of up to 512 GB.
  • Each sd350 server supports up to six 2.5-inch hot-swap drives (which are installed in the enclosure). The sd350 also supports a SATADOM (SATA Drive on Module) drive, which plugs directly into SATA port 1
  • Supports HDDs up to 2 TB capacity and SSDs up to 3.84 TB. Therefore, each server can have up to 23.0 TB of storage capacity using six drives. 64GB SATADOM drive supported.
  • The use of solid-state drives (SSDs) instead of, or along with, traditional hard disk drives (HDDs) can improve I/O performance. An SSD can support up to 100 times more I/O read operations per second (IOPS) than a typical HDD.
  • Three PCIe slots internal to the sd350: One PCIe 3.0 x16 low-profile slot, one PCIe 3.0 x8 slot for an OCP form-factor adapter, and one PCIe 3.0 x8 mezzanine slot for a dedicated RAID adapter.
  • Supports adapters designed for the Open Compute Project (OCP) form factor. OCP delivers efficient server, storage and data center hardware design for scalable computing. Hardware designed for OCP openly shares custom data center designs to improve both cost and energy efficiency across the industry.
  • PCI Express 3.0 I/O expansion capabilities improve the theoretical maximum bandwidth by 60% compared with the previous generation of PCI Express 2.0.
  • With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor E5 family, which reduces I/O latency and increases overall system performance.

Manageability and security

Powerful systems management features simplify local and remote management of the sd350:

  • Supports  Lenovo XClarity Administrator, providing auto-discovery, inventory tracking, monitoring, alerting and call home features.
  • Supports ThinkServer EasyStartup, a graphical tool designed to make it easy to configure the server and install an operating system.
  • Supports ThinkServer Diagnostics (Windows Edition, Linux Edition, Standalone Edition), based on Ultra-X QuickTech diagnostic software, for system diagnostics, information collection, and troubleshooting.
  • Includes an integrated Thinkserver Management Module (TMM) to monitor server availability and perform remote management.
  • Includes a standard RJ45 port for direct connection to the TMM for remote systems management (IPMI 2.0). Alternatively, if an optional Ethernet OCM card is installed, then port 1 of that card can be shared between the operating system and TMM for remote management.
  • An integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup, configuration, and updates, and simplifies error handling.
  • The Intel Execute Disable Bit function can prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system.

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.

Internal storage

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.

The following figure shows the drive bays.

Front view of the n400 showing the drive bays
Figure 6. Front view of the ThinkServer n400 enclosure

The sd350 also supports a SATADOM flash drive, which is installed in SATA port 1 on the system board. See the photo of the internals of the sd350 in the Locations of key components and connectors section for the location of the port.

The following figure shows where the SATADOM drive is installed.

SATADOM flash drive installation
Figure 7. SATADOM flash drive installation.

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.

Controllers for internal storage

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.

Configuration notes with the onboard SATA controller:

  • Only SATA drives are supported
  • Up to 6 drives are supported
  • The controller supports RAID (RAID 0, 1, 5, 10), however only 4 drives can be configured in a RAID array. The remaining 2 drives must be configured non-RAID (JBOD).
  • The onboard SATA controller, when RAID mode (Intel RSTe) is enabled, is not supported by virtualization hypervisors, including VMware ESXi, Linux KVM, Xen, and Microsoft Hyper-V. Non-RAID mode (AHCI mode) is supported by virtualization hypervisors.

Alternatively, the sd350 also supports an H701-L RAID adapter (RAID 0, 1, 10) installed in a dedicated mezzanine slot in the sd350. The H701-L RAID adatper supports a minimum of 2 drives and a maximum of 6 drives. The following figure shows the H701-L adapter (with the attached air baffle removed).

Second processor required: The use of the H701-L RAID adapter requires the second processor be installed.

Systems management

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.

Lenovo XClarity Administrator
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
