IOPS is important for transaction-based applications with random, small-block I/O such as OLTP, databases, Exchange

IOPS performance is heavily dependent on the number and type of disk drives FC and SAS drives generally have faster seek time, lower latency, faster and

rotational velocity and better command queuing compared to SATA Drive-limited configurations can result in similar performance between

systems with different maximum capabilities

Next-generation XOR engine and 8 drive loops in DS4800 help enable it to achieve the achieve the high performance All DS4000 controllers have hardware XOR engines designed for

high-speed RAID parity calculations

What is IOPS?



Benchmark configurationI/O – 4k random reads / writes – RAID 5 – 15,000 RPM disk drivesNote: Results achieved under ideal circumstances in a benchmark test environment at Engenio. Actual customer results will vary based on configuration and infrastructure components.

What is Throughput

MB/s important for throughput-intensive applications with sequential large-block I/O such as video servers, seismic processing, high performance computing (HPC)

Throughput rates are heavily dependent on the internal controller bandwidth

Maximum throughput rates can typically be reached with a smaller number of disk drives (~ 14 to 42) SATA generally delivers up to 66% of FC’s or SAS’ drive-level

performance

DS4800’s internal bandwidth and eight host / drive channels give it an advantage



Throughput – Dual Controller performance

Performance Positioning

Understand the requirements Looking for highest performance = DS4000 series Looking for good performance to value = DS3000 series Is the application best served by FC and SAS, or is SATA HDD ok?

Highest performance of the DS4000 series delivered by DS4800 (FC) IOPS and MB/s (throughput)

Highest performance of the DS3000 series delivered by DS3400 (FC) IOPS and MB/s (throughput)

Additional factors to consider: Consolidation, replication, workload, future headroom



Performance value is price / performance.
