Intel Xeon 6154 (DL380) vs AMD EPYC 7551 (DL385) on HPE ProLiant Gen10

Our partners at HPE have generously provided us with a couple of ProLiant Gen10 servers, and I’m going to do some testing using Red Hat Enterprise Linux 7.4 with KVM. (Update: had to switch to CentOS 7.4 with RDO OpenStack later on).

I’m really excited to see HPE being a front runner with AMD and DL385s, as well as AMD finally releasing a CPU that’s finally (and hopefully) will provide a much needed competition for Intel in the datacentre space.

Here’s the gear I’ll be working with for the next couple of days:

1. HPE ProLiant DL380 Gen10

This one has two Intel Xeon Gold 6154 CPUs and 1.5 TB of RAM (768 GB per CPU socket) in 64GB LRDIMMs. BIOS updated to U30 v1.32 (02/01/2018).

Processor Name Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz
Processor Status  OK
Processor Speed 3000 MHz
Execution Technology 18/18 cores; 36 threads
Memory Technology 64-bit Capable
Internal L1 cache 1152 KB
Internal L2 cache 18432 KB
Internal L3 cache 25344 KB

Networking is HPE Ethernet 10Gb 2-port 562FLR-SFP+ (Intel X710) and HPE Ethernet 10Gb 2-port 562SFP+ (Intel X710) for a total of 4×10 GbE ports, and HPE Ethernet 1Gb 4-port 331i (Broadcom BCM5719).

Storage is pretty basic as we have SAN infrastructure – HPE Smart Array E208i-a SR Gen10 with 2xVK000240GWJPD SSDs (240 GB) in a RAID1 configuration.

2. HPE ProLiant DL385 Gen10

This one has two AMD EPYC 7551 CPUs and 1.5 TB of RAM (768 GB per CPU socket) in 64GB LRDIMMs. BIOS updated to A40 v1.04 (12/12/2017).

Processor Name AMD EPYC 7551 32-Core Processor
Processor Status  OK
Processor Speed 2000 MHz
Execution Technology 32/32 cores; 64 threads
Memory Technology 64-bit Capable
Internal L1 cache 3072 KB
Internal L2 cache 16384 KB
Internal L3 cache 65536 KB

Networking is HPE Ethernet 10Gb 2-port 562FLR-SFP+ (Intel X710) and HPE Ethernet 10Gb 2-port 562SFP+ (Intel X710) for a total of 4×10 GbE ports, and HPE Ethernet 1Gb 4-port 331i (Broadcom BCM5719).

Storage is similar to the one above – HPE Smart Array E208i-a SR Gen10 with 2xVK000240GWEZB SSDs (240 GB) in a RAID1 configuration.

Telia Cloud Platform story at Telia Technology Day 2018 [LT]

In case you’ve missed it or just want a recap, here’s the story about the Telia Cloud Platform’s journey to date, lessons learned and plans for the future, presented at Telia Technology Day 2018 (in Lithuanian).

Storage performance in Telia Cloud Platform

This is going to be quick one because a picture is better than a thousand words.

We have three storage tiers in Telia Cloud Platform – Tier-1 on SSD, Tier-2 on SAS and Tier-3 on NL-SAS, and below are the results from CrystalDiskMark 6.0.0 in a Windows Server 2016 VM on a hpc1.a5 flavor.

As for the IOPS@4KB Q32T1 (click on the links below for a full CrystalDiskMark output):

Telia Cloud Platform test results!

We’ve run a series of tests to provide our customers with a reference as to what can be expected from the platform flavors.

These tests span across a number of GC1 (B3, B7, B11, B17) and HPC1 (A3, A7, A11, A17) flavors. In a nutshell, we demonstrate the vCPU, RAM and combined system performance for 2, 4, 8 and 16 vCPUs with 4 GB, 16 GB, 32 GB and 128 GB of RAM respectively.

We’ve used Phoronix testing suite to run a series of tests on CentOS Linux 7, Kernel: 3.10.0-693.17.1.el7.x86_64 (x86_64), Compiler: GCC 4.8.5 20150623,
File-System: xfs, Screen Resolution: 1024×768, System Layer: KVM.

The tests were run on a live system in a production environment, i.e. no fake or demo lab setups, and artificially boosted numbers.

The tests are completed, a combined output is available here: Telia Cloud Testing Results.
