Hitachi VSP G1000 Fastest All-Flash Array Validated by SPC-1, said HDS
Best throughput and response time in front of Kaminario and Huawei
This is a Press Release edited by StorageNewsletter.com on March 11, 2015 at 3:15 pmIn a blog entitled VSP G1000: The Fastest All-Flash Array Validated by SPC-1, HDS CTO Hu Yoshida wrote:
The System Performance Council SPC-1 tests results for Hitachi VSP G1000 have just been published on the SPC website and the results show that the G1000 is the clear leader in storage performance against the leading all flash storage arrays! VSP G1000 can be configured as an all-flash storage array simply by not adding any spinning disks.
Top 10 Storage Systems Comparison – SPC-1 Benchmark Chart

The chart above is constructed from data on the SPC-1 website which shows the audited results of the SPC -1 test that was run on different all-flash storage systems. This test consists of a single workload designed to demonstrate the performance of a storage subsystem 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 these types of applications include OLTP, database operations, and mail server implementations. The chart above compares the performance results of several all-flash arrays with the VSP G1000 with only 64 Hitachi Flash Module devices.
The results show that the G1000 is the clear performance leader with less than 1ms response time at over 2 million IO/s! The G1000 had 60% greater throughput and one-third the full-load response time than the previous performance leader that used a specialized, niche DRAM-based systems.
Response Time – Throughput Data | SPC-1 Table
This table comes from the SPC-1 report and shows the response time and throughput at different% of benchmark load with different Application Storage Unit (ASU) Capacity. To net it out, at 100% load, using the total ASU of 64 Flash Module Devices, VSP G1000 produced a throughput of 2,004,941.89 IO/s with an average response time of 0.96ms.
The G1000 is not only an all-flash array it is also a full function enterprise storage system, the first enterprise storage system to achieve $1.00/SPC-1 IO/s. Since it is an enterprise array, the G1000 also has the capability to dynamically provision and automatically tier data across internal and external pools of lower cost, higher capacity disk drives. While the G1000 provides additional functionality, scalability and cost savings over all-flash arrays, this capability disqualifies the G1000 as an all-flash array according to Gartner. Gartner defines an all-flash or solid-state array as one that cannot attach any disk drives. As a result, you will not find the G1000 in the Gartner Magic quadrant for solid-state arrays even though it has, by far, the highest performance of any solid-state or all flash array. Customers who rely on the Gartner Magic Quadrant may not realize the all-flash benefits of VSP G1000 and HUS VM.
If you are looking for the best all flash storage system, checkout the SPC-1 report on the SPC-1 website first since performance is the primary reason for an all-flash array. Then checkout the Gartner Critical Capabilities for General-Purpose High-End Storage Arrays or if you are into Magic Quadrants you can check out Gartner’s Magic Quadrant for General-Purpose Disk Arrays and see where the leader in performance ranks in terms of Gartner’s other comparative reports. The G1000 ranks at the top for Gartner’s critical capabilities and HDS ranks near the top in the Magic Quadrant. Unfortunately the leader in this magic quadrant does not participate in the SPC-1 evaluation so we have no way to compare their performance or validate their performance claims.
