Dear Phany,
Factors affecting performance of flash storage:
1. Capacity usage: percentage of used capacity in the total capacity. A higher capacity usage indicates lower performance.
2. Whether deduplication/compression is enabled.
3. Performance varies for different I/O models. Different service scenarios have different proportions of large I/Os (greater than 16 KB) and small I/Os (smaller than 8 KB). Applications with large I/Os: OA systems, Exchange, NAS storage converting to SAN storage, and backup and archiving. Applications with small I/Os: database, VDI in most normal operation scenarios, and VSI in most normal operation scenarios.
The following table lists actual performance of Dorado V3 (V3R1C01):
| 8K I/O | 32K I/O |
Dorado6000 V3 | 330K IOPS@1ms | 200K IOPS@0.5ms | 150K IOPS@1ms | 12 GB/s |
Dorado5000 V3 | 200K IOPS@1ms | 145K IOPS@0.5ms | 100K IOPS@1ms | 9GB/s |
Test module: 1. 8K I/O：Dual-controller，7:3 read and write ratio, 100% random, and RAID 5, 6, or TP，Inline deduplication & compression，80% SSD capacity utilization 2. 32K I/O IOPS：Dual-controller，7:3 read and write ratio, 100% random, and RAID 5, 6, or TP，Inline compression，80% SSD capacity utilization 3. 3）32K I/O Bandwidth：Dual-controller，100% read ratio，100% random, and RAID 5, 6, or TP， 80% SSD capacity utilization |
Actual performance of Dorado V3 is one of the most leading ones in the storage industry. Its performance outperforms that of traditional storage under the same testing conditions and doubles that of XtremIO, a star product in the field of all-flash storage.
Dorado V3 not only has an excellent IOPS but also keeps stable performance in applications (such as snapshot) that are performance bottlenecks for traditional storage.
I hope it is helpful to you!
