16. Applications in IT
Implementation Models
1. SSDs in Server as Disk
2. Hybrid Storage Arrays
a. Tiering
3. All Solid State Storage Arrays
4. Caching

17. Applications in IT
Caching
1. Storing frequently accessed data on very fast media
2. Array-based flash caching
3.Server-based flash caching

18. Applications in IT
Storage Tiering
▪ Faster most I/O-intensive
workloads
▪ Slower least I/O-intensive
workloads
SSD
Tier 3
SAS
Tier 2
SATA
SATA
Tier 1

19. Applications in IT
Virtualization
1. Virtualization throws I/O into a
blender. All I/O is now random
I/O!
1. 10 VMs doing sequential I/O to
the same datastore=random
I/O
Tier 2
1. Hard Disk drives are good at
Tier 1
sequential, less good at
random

20. SSDs in Servers & Storage Arrays
Data Integrity & Availability = Highest Importance
▪ Require Full Data Path Protection
▪ Enterprise - Capacitor / Battery
▪ Designed for Longer Service Life

21. SSDs in Servers & Storage Arrays
Performance
▪ Enterprise - Very Consistent
▪ Storage Arrays - Mismatched
➢Impact on Latency & Quality of Service

22. SSDs in Client Devices
Benefits & Challenges
▪ Benefits
• Startup Time
• Read/Write Performance
• Power Consumption
• Durability
▪ Challenges
•Cost

23. SSDs in Client Devices
Benefits & Challenges
Alternatives
• SSD or HDD Cache
• Intel SRT Technology
