Re: Real world performance impact for SSD opposed to spinning drives

My guess is your going to be very pleased.

There’s a tool call disk magic from IBM that you or your partner could use
to some predictive modeling on if you want more specific results.

Honestly I doubt I would spend the time. 6 to 5 devices should not affect
the I/O channels enough to make a difference plus the speed of the SSD vs.
spinning drives.

Go for it.

I’ve done this for other customers and the performance difference has been
almost shocking.

Not to mention the difference in CPU.

OK... we are in the process of spec'ing out a new box in the near future
(via an existing business partner)...

We are currently on a 8286-41a with 6 140g 15k drives...

One of the proposed replacements is a 9009-41A with 5 387GB Enterprise SAS
4k SFF-3 SSD drives...

This machine has a workload of serving a Websphere/HTTP website and a
Domino server with around 150 users total...


I am curious if anyone has any comments or hunches on what real world
performance enhancement that might be seen down at the user experience
level (in general)...


We have only used SSD drives in some laptops/PCs... which is very
noticeable at that level, but we aren't sure what to expect on a server
accessed thru different machines/browsers/Citrix servers, etc...
