Requires 3 Symphonic SSDs
Requires 17 leading FTL SSDs
66% Read/33% Write test mix with QoS defined as total read and write latency for 99.0% of operations:
- Three Symphonic SSDs achieve 957K IOPS at 99.0% QoS at 2.7 ms, even without a read/write cache
- To match a 99.0% QoS at 2.7 ms, a leading FTL SSD will have to be down throttled to 56K IOPS
- Delivering an equivalent 952K IOPS at 99.0% QoS at 2.7 ms requires 17 leading FTL SSDs, each utilizing a read/write cache
Requires 3 Symphonic SSDs
Requires 56 leading FTL SSDs
Utilizing the more common definition of QoS latency defined at 99.99% of operations:
- Same 66% Read/33% Write test but with QoS defined as total read and write latency at 99.99% of operations
- Three Symphonic SSDs achieve 957K IOPS at a 99.99% QoS at 3.1 ms without a read/write cache
- To match a read/write 99.99% QoS at 3.1 ms requires down throttling the FTL SSD to 17K IOPS
- Delivering an equivalent 952K IOPS at 99.99% QoS at 3.1 ms requires 56 leading FTL SSDs each with a read/write cache
