Stable Storage

Solution Under Test Configuration Notes

The benchmark was ran on a single PowerEdge R6715 server with local NVMe storage disks. RAID0 config was created using the drives and EXT4 file system was setup on the RAID0. Ubuntu 24.04.1 OS was installed on an internal NVMe drive. There were no additional external clients or storage devices or network devices were connected to this setup. The new PowerEdge R6715 system has a AMD EPYC 9355P (32cores) processor and 16 NVMe drives were connected to support lots of disk storage and good storage performance. The testing was done with SMT enabled in BIOS, providing 64 cpu threads for more processing power.

Other Solution Notes

Dataflow

This single server setup has a RAID0 partition created on the local storage drives and EXT4 file system was created on the RAID. Data gets written directly on to the EXT4 filesystem and on to the NVMe storage devices. No other external storage device was used.

Other Notes

The benchmark was ran on a single DELL Technologies PowerEdge R6715 server using its local NVMe drives. This benchmark was tested on Ubuntu 24.04.1 OS with kernel 6.8.0-45-generic. No other client system, or external storage device or networking device was connected to this test system. None of the components used to perform the test were patched with Spectre or Meltdown patches (CVE-2017-5754, CVE-2017-5753, CVE-2017-5715). Vulnerabilities: Gather data sampling: Not affected Itlb multihit: Not affected L1tf: Not affected Mds: Not affected Meltdown: Not affected Mmio stale data: Not affected Reg file data sampling: Not affected Retbleed: Not affected Spec rstack overflow: Not affected Spec store bypass: Mitigation; Speculative Store Bypass disabled via prctl Spectre v1: Mitigation; usercopy/swapgs barriers and __user pointer sanitization Spectre v2: Mitigation; Enhanced / Automatic IBRS; IBPB conditional; STIBP always-on; RSB filling; PBRSB-eIBRS Not affected; BHI Not affected Srbds: Not affected Tsx async abort: Not affected
