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

SSD

SAS

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
