Description of support work: Hi
I run an open source consultancy (CRM, ERP, Workflow type solutions) and currently working on a project where the customer has asked us to install the application in 2 VPS on a private cloud. 1 VPS for the CRM application, 1 VPS for the mySQL database.
We would typically expect the disc read/write speed to be 200mbps to 300mbps, however here they seem to be much slower, 2 to 80mbps. This private cloud was installed and is managed by a 3rd party IT company.
They have provisioned a total of 6 VPS now, all running at different speeds, but none where they should be. Our customer has discussed this issue with their IT company who have replied 'everything is fine, no issues' and they have said the issue must be a database config issue........we haven't ruled anything in/out however if we stop the database completely disc performance doesn't improve and all we have done (several times now) is install mySQL we haven't changed anything or done any performance tuning yet.
We want to take a 2 step approach:
1. Prove that the issue is/isn/t with the servers/SAN.....all we have done so far is a hdparm -tT (also did test with DD for write speed) to test the read/write speed of the discs.......is there anything else that we can do to rule in/out the issue is with the servers/SAN?
2. If we can prove that the issue is with the servers/SAN then there will be a bigger opportunity in identifying and fixing the underlying issue.
This is what our customer has in place today.....
Blade Server – A fully populated chassis containing 4 blade servers. Each blade server has 96Gb RAM and 2 quad core 2.8Ghz processors – 3 Blades in use, 1 Blade spare.
Storage Device – Raid 5 Enterprise class SAN 8-9Tb capacity – iSCSI interface between SAN and Blade Server.
Since upgrading, the performance of all of our systems improved enormously.
It’s difficult to estimate just how much spare capacity we have but I’d say that conservatively, we are only using 40% to 50% of total resources, so the CRM systems should be performing extremely well not poorly.
