Lenovo ThinkSystem SR570 Server Review

by Adam Armstrong

The Lenovo ThinkSystem SR570 is a 2-socket 1U server that can be used by the entire gamut of SMB to large enterprises. The server offers a balance of performance, memory, and storage. This balance leads to versatility allowing the SR570 to be used in a wide range of workloads, such as virtualization and cloud computing, infrastructure security, web serving, and application development. The SR570 is also a popular option for software-defined solutions, of which Lenovo supports many via their ThinkAgile platforms, that have a heavier reliance on compute density than storage footprint.

This balance leads to versatility allowing the SR570 to be used in a wide range of workloads, such as virtualization and cloud computing, infrastructure security, web serving, and application development. The SR570 is also a popular option for software-defined solutions, of which Lenovo supports many via their ThinkAgile platforms, that have a heavier reliance on compute density than storage footprint.

Under the hood, the SR570 can sport up to two Intel Xeon Scalable CPUs for up to 26 cores, up to 1TB of 2666MHz TruDDR4 RAM, and up to 10 2.5-inch drives (or up to 4 3.5” drives) with the users choice of NVMe, SAS, or SATA SSDs, and 3 PCIe slots and one optional LOM slot. The Lenovo ThinkSystem SR570 server can fit all of the above in a compact 1U frame. 

The SR570 has the potential for great performance and is highly versatile. There are multiple storage options (including the additional of Lenovo’s AnyBays that fit multiple interfaces in the same bay) that can allow users to have either the capacity or media type needed in a 1U footprint. The server also supports several networking and PCIe card options depending on customer needs. To top off everything the server is affordable starting at just $2,300 USD.

Our particular build consists of two Intel Xeon Gold 5118 Processors, 384GB of RAM, and we leverage four 4TB Memblaze PBlaze5 Mixed Use NVMe SSDs.

Design and Build

The Lenovo SR570 is a 1U server that comes in two configurations, either four large form factor (3.5”) bays across the front, or up to 10 small form factor (2.5”) bays. Our review unit offers six SATA/SAS bays in addition to four 2.5" NVMe-enabled bays. The drive bays take up most of the front of the server on the left side across the front. On the right side are the power button, USB 3.0 port, status LEDs, USB 2.0 port, and optional VGA port (the configuration is slightly different with the LFF layout with some of the above across the top). 

Flipping the server around to the rear we see two hot-swappable PSUs on the right, two USB 3.0 ports to the left of the PSUs, followed by a VGA port, two RJ-45 GbE ports, a 10/100/1000 Mb Ethernet port for XCC, an optional LOM card slot, and up to three PCIe slots on top. 

The top view shot shows the clean airflow pathways across the internal components with minimal obstructions. Cooling is provided through six fans, split evenly on the left and right side for each CPU.

The NVMe bays in this server offer direct attachment to the motherboard, which helps out by not consuming a PCIe slot. We've seen a number of servers that require sacrificing a precious (in a 1U server) slot to add NVMe, which makes additional expansion more difficult.

In addition the ThinkSystem SR570 includes an onboard M.2 connector for handling onboard boot storage. This further lets a user stretch the configuration to be customized to the use case itself, versus taking over resources that could instead be allocated to better uses. 

Management

For ThinkSystem and ThinkAgile systems, Lenovo offers XClarity for management. XClarity centralizes and streamlines hardware resource management, speeds cloud as well as traditional infrastructure deployment, and enables visibility and control of physical resources from external, higher level management software tools. 

On the main screen XClarity lays everything out for users to see quickly and easily. There are five main windows that show a Health Summary (that breaks down various hardware components), Quick access (for actions such as turning the system on or off), a Remote Console Preview, System Information and Setting, and Power Utilization. Down the right side of the screen are main tabs including: Home, Events, Inventory, Utilization, Remote Console, Firmware Update, Server Configuration, and BMC Configuration.

The Event tab is exactly like it sounds. It lists events with an ID, a message as to what it was, and a time and date when it happened. Users can use this screen to go through audit logs, maintenance history, and alert recipients.

The Inventory tab lists the various hardware components of the server and gives a basic description, i.e. how many cores per CPU or the capacity of RAM.

Users can drill down deeper into individual parts and gather more specific information. This is good if there is an issue or a replacement needs to be ordered.

The Utilization tab shows what resources and how much of those said resources are being used by the server and offers either graphical or a table view.

The Remote Console tab shows a review of what a remote console would look like as well as allowing users to configure their remote consoles.

With the Firmware Update tab, admins can see system and/or adaptor firmware updates that are available and manually update them.

The next main tab is Server Configuration with several sub tabs including Adapters, Boot Options, Power Policy, RAID Setup, and Sever Properties. The Power Policy allows admins to set up either redundant or non-redundant as well as set the power restore policy: setting it to stay off, on, or revert to the previous settings after a power restore.

Performance

SQL Server Performance

StorageReview’s Microsoft SQL Server OLTP testing protocol employs the current draft of the Transaction Processing Performance Council’s Benchmark C (TPC-C), an online transaction processing benchmark that simulates the activities found in complex application environments. The TPC-C benchmark comes closer than synthetic performance benchmarks to gauging the performance strengths and bottlenecks of storage infrastructure in database environments.

Each SQL Server VM is configured with two vDisks: 100GB volume for boot and a 500GB volume for the database and log files. From a system resource perspective, we configured each VM with 16 vCPUs, 64GB of DRAM and leveraged the LSI Logic SAS SCSI controller. While our Sysbench workloads tested previously saturated the platform in both storage I/O and capacity, the SQL test looks for latency performance.

This test uses SQL Server 2014 running on Windows Server 2012 R2 guest VMs, and is stressed by Dell's Benchmark Factory for Databases. While our traditional usage of this benchmark has been to test large 3,000-scale databases on local or shared storage, in this iteration we focus on spreading out four 1,500-scale databases evenly across our servers.

SQL Server Testing Configuration (per VM)

  • Windows Server 2012 R2
  • Storage Footprint: 600GB allocated, 500GB used
  • SQL Server 2014
    • Database Size: 1,500 scale
    • Virtual Client Load: 15,000
    • RAM Buffer: 48GB
  • Test Length: 3 hours
    • 2.5 hours preconditioning
    • 30 minutes sample period

For our transactional SQL Server benchmark the SR570 had an aggregate score of 12,631.39 TPS with individual VMs ranging from 3,156.91 TPS to 3,160.53 TPS.

With SQL Server average latency the SR570 gave us an aggregate score of 6.5ms with individual VMs ranging from 2ms to 8ms.

Sysbench MySQL Performance

Our first local-storage application benchmark consists of a Percona MySQL OLTP database measured via SysBench. This test measures average TPS (Transactions Per Second), average latency, and average 99th percentile latency as well.

Each Sysbench VM is configured with three vDisks: one for boot (~92GB), one with the pre-built database (~447GB), and the third for the database under test (270GB). From a system resource perspective, we configured each VM with 16 vCPUs, 60GB of DRAM and leveraged the LSI Logic SAS SCSI controller.

Sysbench Testing Configuration (per VM)

  • CentOS 6.3 64-bit
  • Percona XtraDB 5.5.30-rel30.1
    • Database Tables: 100
    • Database Size: 10,000,000
    • Database Threads: 32
    • RAM Buffer: 24GB
  • Test Length: 3 hours
    • 2 hours preconditioning 32 threads
    • 1 hour 32 threads

With the Sysbench OLTP we tested 4VM and the SR570 had an aggregate of 4,247.9 TPS.

With Sysbench latency the server had an average of 22.6ms.

In our worst-case scenario (99th percentile) latency the SR570 gave us 46.53ms.

VDBench Workload Analysis

When it comes to benchmarking storage arrays, application testing is best, and synthetic testing comes in second place. While not a perfect representation of actual workloads, synthetic tests do help to baseline storage devices with a repeatability factor that makes it easy to do apples-to-apples comparison between competing solutions. These workloads offer a range of different testing profiles ranging from "four corners" tests, common database transfer size tests, as well as trace captures from different VDI environments. All of these tests leverage the common vdBench workload generator, with a scripting engine to automate and capture results over a large compute testing cluster. This allows us to repeat the same workloads across a wide range of storage devices, including flash arrays and individual storage devices.

Finally, VDI LC Monday Login had the SR570 start at 17,606 IOPS and 111.3μs latency before going on to peak at 181,479 IOPS at 319.4μs.

Conclusion

The Lenovo ThinkSystem SR570 is a compact 1U, 2-socket server aimed at virtualization and cloud computing, infrastructure security, web serving, and application development. Of course these use cases run the gamut from small offices to larger enterprises. This small server can be outfitted with up to 1TB of ram, two Platinum Intel Xeon CPUs, and up to 76.8TB of capacity, depending on the drive configuration chosen. In addition to standard server use cases, the SE570 can find itself in a variety of software-defined solutions via Lenovo's ThinkAgile suite of offerings.

In our application workload analysis the ThinkSystem SR570 was limited more by our exact configuration of the processors versus its potential given four NVMe SSDs. We were able to hit aggregate scores of 12,631.39 TPS and an average latency of 6.5ms in SQL Server. In Sysbench the sever had an average TPS score of 4,247.9 with average latency of 22.6ms and worst-case scenario latency of 46.53ms. With a more stout CPU configuration you can easily double the compute resources available and net better overall system performance.

For VDBench, the SR570 had sub-millisecond latency performance in every test. Peak performance highlights include in random 4K read the server hit 2.8 million IOPS, 1.52 million IOPS in random 4K write, 13.6GB/s in 64K sequential read and 7.3GB/s in sequential 64K write. The SR570 showed some impressive numbers in our SQL and Oracle tests with SQL score of 832K IOPS, 90-10 score of 797K IOPS, and 80-20 score of 723K IOPS. For Oracle it hit 720K IOPS, 638K IOPS for 90-10, and 603K IOPS for 80-20. Latency is interesting to note here at the server had a high peak latency of 548.4μs and a low peak latency of only 73.3μs.

The Lenovo ThinkSystem SR570 is a versatile server that can fit many needs with a wide range of configuration options. The server is capable of offering high-end compute performance with NVMe SSDs, or it can be configured for less performant needs at a much lower cost. In either case it's a great offering for instances where compute needs and server density outweigh the need for massive storage and add-in card flexibility.
