The SNIA Solid State Storage Initiative (SNIA SSSI) is pleased to provide a testing service where interested parties may submit their SSD products for testing to the SSS Performance Test Specification.
Drive Requirements
Any mSATA, SATA, SAS and PCIe SSDs can be tested. The tested device must be recognized as a logical device by CentOS 6.3 and must support Purge (via Security Erase, Format Unit, or equivalent proprietary method of Purge).
Available Tests
Testing is based on the SSS PTS version 1.1 The following tests are available. Visit the SSS Performance Test Specification page for more information on the tests.
1. SAS/SATA BASIC
Tests run:
-
Write Saturation (WSAT): continuous RND Ws - FOB, no Pre conditioning, to Steady State
-
IOPS:RND IOs Per Second (56 R/W x Block Size matrix) - Pre conditioned to Steady State
-
Throughput (TP): Large Block SEQ R/W in MB/sec - Pre conditioned to Steady State
-
Latency (LAT): Ave & Max Response Times at 3 BS & 3 R/W Mixes - Pre conditioned to Steady State
2. SAS/SATA EXTENDED
Tests run:
-
Cross Stimulus Recovery (XSR):Changing between sustained periods of SEQ & RND Ws
-
Host Idle Recovery (HIR):Periods of RND Ws interspersed w/ varying Idle times
-
Enterprise Composite Workload (ECW):Mixed Block Size & R/W mix probability stream
-
Demand Intensity Response Time Histograms (DIRTH): IOPS reached at a given Demand Intensity (OIO) and Max Response Time level
3. PCIe BASIC
Tests run:
-
Write Saturation (WSAT): continuous RND Ws - FOB, no Pre conditioning, to Steady State
-
IOPS:RND IOs Per Second (56 R/W x Block Size matrix) - Pre conditioned to Steady State
-
Throughput (TP): Large Block SEQ R/W in MB/sec - Pre conditioned to Steady State
-
Latency (LAT): Ave & Max Response Times at 3 BS & 3 R/W Mixes - Pre conditioned to Steady State
4. PCIe EXTENDED
Tests run:
-
Cross Stimulus Recovery (XSR):Changing between sustained periods of SEQ & RND Ws
-
Host Idle Recovery (HIR):Periods of RND Ws interspersed w/ varying Idle times
-
Enterprise Composite Workload (ECW):Mixed Block Size & R/W mix probability stream
-
Demand Intensity Response Time Histograms (DIRTH): IOPS reached at a given Demand Intensity (OIO) and Max Response Time level
Testing Process
Testing will be conducted by Calypso Systems, a certified SSS PTS testing facility. Contact ptstest@snia.org for pricing.
Participants must submit two (2) samples of the SSD to be tested and provide prepaid return express shipment bills (FedEx, DHL or UPS).
Testing will take approximately 3-4 weeks to complete.
Any failed test, or test that will not complete, will be tested twice and error logs will be provided.
All product test result data will be kept confidential.
Test results are provided in standard SNIA Report Format as specified in the SSS Performance Test Specification.
.For more details, contact ptstest@snia.org.
