I have a media server that has poor performance and was reading about using IOmeter to troubleshoot. It states to convert the disk to MBR if using GPT. I am wondering if GPT could be the reason for poor performance or if needing MBR is just an IOmeter limitation.
Thanks.

Hello
The cost and availability of SSD storage now days means it is very easy to get a few TB available and dedicated to a Media agent for the DDB its self.
The DDB does not take up much space when compared to the disk library size but has high performance requirements. you will always have IO related issues with you are just using a datastore presented disk from your day to day use array.
I would guess you could get some improvement by making the change to MBR but in realistically it will be a tiny % increase when compared to just getting a SSD for the MA.
Kind regards

Hello
Thanks for the great question, can you advise the hardware vendor and model of the disks you are testing? I have not seen a case when making the change between GPT and MBR have been used to resolve a disk performance issue.

Thanks for your reply Albert.
The media server is a virtual machine backed by NFS datastores, it has high Q&I time, and is being replaced with a physical server. I just saw the troubleshooting document and wondered if could be a contributor and if MBR is a better choice for the new server.
Thanks.
