Sun Flash Accelerator F20 PCIe Cards Outperform IBM on SPC-1C

Oracle's Sun Flash Accelerator F20 PCIe cards delivered outstanding value as measured by the SPC-1C benchmark, showing the advantage of Oracle's Sun FlashFire technology in terms of both performance and price/performance.
  • Three of Sun Flash Accelerator F20 PCIe cards delivered an aggregate of 72,521.11 SPC-1C IOPS, achieving the best price/performance (TSC price / SPC-1C IOPS).

  • The Sun Flash Accelerator F20 PCIe cards delivered 61% better performance at 1/5th the TSC price than the IBM System Storage EXP12S.

  • The Sun Flash Accelerator F20 PCIe cards delivered 9x better price/performance (TSC price / SPC-1C IOPS) than the IBM System Storage EXP12S.

  • The Sun F20 PCIe Flash Accelerators and workload generator were run and priced inside Oracle's Sun Fire X4270M2 server. The storage and workload generator used the same space (2 RU) as the IBM System Storage EXP12S by itself.

  • The Sun Flash Accelerator F20 PCIe cards delivered 6x better access density (SPC-1C IOPS / ASU Capacity (GB)) than the IBM System Storage EXP12S.

  • The Sun Flash Accelerator F20 PCIe cards delivered 1.5x better price / storage capacity (TSC / ASU Capacity (GB)) than the IBM System Storage EXP12S.

  • This type of workload is similar to database acceleration workloads where the storage is used as a low-latency cache. Typically these applications do not require data protection.

Benchmark Description

SPC Benchmark 1C? (SPC-1C) is the first Storage Performance Council (SPC) component-level benchmark applicable across a broad range of storage component products such as disk drives, host bus adapters (HBAs), intelligent enclosures, and storage software, such as, Logical Volume Managers. SPC-1C utilizes an identical workload to SPC-1, which is designed to demonstrate the performance of a storage component product, while performing the typical functions of business critical applications. Those applications are characterized by predominately random I/O operations and require both queries, as well as, update operations. Examples of those types of applications include OLTP, database operations, and mail server implementations.

SPC-1C configurations consist of one or more HBAs/Controllers and one of the following storage device configurations:

  • One, two, or four storage devices in a stand alone configuration. An external enclosure may be used, but only to provide power and/or connectivity for the storage devices.

  • A "Small Storage Subsystem" configured in no larger than a 4U enclosure profile (1 - 4U, 2 - 2U, 4 - 1U, etc.).

Key Points and Best Practices

  • For best performance, insure partitions start on a 4K aligned boundary.

Performance of Sun 7410 and 7310 Unified Storage Array Line

Roch (rhymes with Spock) Bourbonnais, posted more data showing the performance of Sun's OpenStorage products.  Some of his basic conclusions are:

  • The Sun Storage 7410 Unified Storage Array delivers 1 GB/sec throughput performance.
  • The Sun Storage 7310 Unified Storage Array delivers over 500 MB/sec on streaming writes for backups and imaging applications.
  • The Sun Storage 7410 Unified Storage Array delivers over 22000 of 8K synchronous writes per second combining great DB performance and ease of deployment of Network Attached Storage while delivering the economics benefits of inexpensive SATA disks.
  • The Sun Storage 7410 Unified Storage Array delivers over 36000 of random 8K reads per second from a 400GB working set for great Mail application responsiveness. This corresponds to an entreprise of 100000 people with every employee accessing new data every 3.6 second consolidated on a single server.
