Access "Using all-SSD arrays to turbocharge your data center"
This article is part of the June 2013, Volume 2, Number 6 issue of Understanding infrastructure and platform as a service
Over the past decade, compute power has increased nearly 30-fold and networks have increased in speed roughly 100-fold. During that time, hard disk drive (HDD) technology has not significantly increased in either rotational speed or total throughput. Adding a solid-state drive (SSD) tier to an HDD array is like adding a turbocharger to a car engine. But adding an all-SSD array? That's like replacing it with a jet engine. All-SSD Arrays Part 1: Using all-SSD arrays to turbocharge your data center Part 2: Emerging all-SSD arrays deliver performance boost to data centers Adding more capacity to a storage array increases available performance, as measured byIOPS (I/O operations per second), so storage sizing considerations have to include both capacity and performance. Crunching the numbers When comparing the merits of HDD versus SSD arrays, IOPS is a key measurement. Consider that a RAID group with four 400 GB 15 K SAS drives would yield approximately 700 raw IOPS (175 per drive). If an application required 900 IOPS, it would be necessary to add two drives to ...
