l 
Web transactions PLUS unpredictable batch schedules
Low budget for storage, ?!?#%& requirements for latency
Random spikes in storage array usage
Wins:
– 
– 
– 
– 
Batch execution times reduced by 60/70%
Predictable response times for web users
Strain reduced on storage array
Storage costs kept down (NLSAS vs SAS etc)

Scenario #2: MySQL
l 
MySQL env:
– 
– 
– 
l 
Web transactions generating INSANE spikes of read/write I/O

– 
– 
Contention disappeared «magically»
Strain reduced on storage array & replica
Blazing fast response times for end users

Compile/Build farm:
– 
– 
– 
l 
Performance not a critical issue
Small footprint on storage etc (cheap storage, no replica, etc.)
«Works this way» feeling.
Wins:
– 
– 
– 
Compile time reduced by 40/60%
Stronger parallelization of build jobs
Aid in SDLC
