Flash Storage technologies are opening up a wealth of new opportunities for improving the optimisation of applications, data and storage, as well as reducing costs. In this session, Peter Mason, NetApp Consulting Systems Engineer, shares his experiences and discusses the use and impact of different Flash technologies.

1. Flash Storage:
The Need For Speed

2. Disk Trends over the Years
 1956 75KB, 1200rpm, 176B/sec
 1973 100MB, 1500rpm, 800KB/sec
 1985 700MB
 2003 72GB, 7200rpm, 80MB/sec
 2013 600GB, 15000rpm, 180MB/sec
Increase of x 6.6million capacity, x 1million performance
Last 10 years x10 (or more) capacity, x2 performance
 Then came Solid State Drives, 500MB/sec

3. Random IOPS and Latency
 SAS delivers around 180 IOPS
– Typical latency of 1 msec to 20+ msec
 SATA delivers around 40 IOPS
– Typical latency of 4 msec to 20+ msec
 SSD delivers around 10000 IOPS
– Typical latency of under 1 msec

10. Hybrid Arrays with
Virtual Storage Tier
10

11. Storage Tiers – Beware of the Traps
 Tiering of data is a popular hybrid
 How long does it take to move data between the tiers?
 How much work is involved in defining tiering policies?
 What’s the impact on snapshots, backups etc.
 How does tiering impact/compliment dedupe/compression
