Applications in IT
1.SSDs in Server as Disk
2.Hybrid Storage Arrays
a. Tiering
3.All Solid State Storage Arrays
4.Caching
Implementation Models
Applications in IT
1.Storing frequently accessed data on very fast media
2.Array-based flash caching3.Server-based flash caching
Caching
Applications in IT
▪ Faster most I/O-intensive workloads
▪ Slower least I/O-intensive workloads
Storage Tiering
Tier 1
Tier 2
Tier 3

SATA
Applications in IT
1.Virtualization throws I/O into a blender. All I/O is now random I/O!
2.10 VMs doing sequential I/O to the same datastore=random I/O
3.Hard Disk drives are good at sequential, less good at random
Virtualization
Tier 1
Tier 2
SSDs in Servers & Storage Arrays
▪ Require Full Data Path Protection▪ Enterprise - Capacitor / Battery▪ Designed for Longer Service Life
Data Integrity & Availability = Highest Importance
SSDs in Servers & Storage Arrays
▪ Enterprise - Very Consistent▪ Storage Arrays - Mismatched
➢Impact on Latency & Quality of Service
Performance
SSDs in Client Devices
▪ Benefits•Startup Time•Read/Write
Performance•Power Consumption•Durability
Benefits & Challenges
▪ Challenges•Cost
SSDs in Client Devices
Alternatives
• SSD or HDD Cache• Intel SRT Technology
• SSHD (Solid-State Hybrid Drive)• Larger RAM cache on drive controller
