holz's questions

The company that I am working for is looking at doing a data upgrade on a database to go from one version of an application to the next (Axapta 3 to Ax 2009). This process is very IO intensive and with our current setup will take a few days. We currently have a HP Lefthand SAN with 24 450GB 15k disks. We are running the SAN over iSCSI (2x 1gb nics) which limits us to a max through put of about 100MB/s.

We are currently looking for ways to increase the IO performance for the duration of the upgrade. The server that will be running the upgrade will be a HP DL360 G7, which has 8 SAS ports and a HP p410i RAID controller.

We only need about 400GB space for the data and the log-files.

We we thinking about maybe getting 8 SSD's add putting them in the server and setting up a RAID 10 array just for the weekend. I have read that the performance of consumer SSD's degrade when doing lots of write operations. As we only need this solution to work for just one weekend, should I be worried about this if we purchase consumer grade SSD's? Would the Intel X25-M series disks be okay or should we go for the X25-E.

Our datacenter and head office is currently in Brisbane, Australia, and we have a branch office in the UK. We have a private WAN with a 768k link to our UK office and the latency is at about 350ms.

The terminal server performance is reeeeealy bad.

Applications that don't have too much animation or any images seem to be okay. But as soon as they do, the session is almost unusable. Powerpoint and internet explorer are good examples of apps that make it run slow. And if there is an image in your email signature, outlook will hang for about 10 seconds each time a new line is inserted, while the image gets moved down a few pixels.

We are currently running server 2003. I have tried Server 2008 R2 RDS, and also a third party solution called Blaze by a company called Ericom, but it is still not too much better.

We currently have a 5 levels dynamic class of service with the priority in the following order.

1. VoIP
2. Video
3. Terminal Services
4. Printing
5. Everything else

When testing the terminal server performance, the link was monitored using net-flows, and we have plenty of bandwidth available, so I believe that it is a latency issue rather than bandwidth.

Is there anything that can be done to improve performance. Would citrix help at all?

Are there any apps or scripts that will remove all temporary internet files for all users on a windows 2003 terminal server.
