Re: [ActiveDir] OT: Disk Capacity

[Al Mulnick]

I agree with Brian, but I'll add to that the consideration of how those images are going to be used. For example, are they going to be read frequently? Moved around? Or is this just long term storage? What is your storage lifecycle expectation for these pictures? That could sway your decision about whether or not RAID 5 is a good performance choice or not.

 

Pictures tend to be blobs.  As such, your performance hit could easily come during the writes because of the parity check of a RAID 5 volume.  RAID 5 is usually a good read configuration and as such is often used for DB applications heavy write scenarios. Some file/print apps like it as well however because of the random nature of file/print. If you start to notice some performance issues related to uploads, check there after looking at the anti-virus and logs.

If it's very high write volume you may see issues, but otherwise you should be fine.

 

Not sure why you would need a firmware upgrade, but, you can always grab the Proliant support pack from HPQ and let it tell you what versions are current for your HW.

Hi,

 

I have a Compaq ML370 Proliant Tower Server, our lab department are creating digital images that are 30mb per pic so I need lots of storage space.

 

I am thinking of putting in 4x300gb Ulta320 SCSI drives in a RAID5 set, does anyone see any performance problems with this?

 

Does anyone have any experience if I need to upgrade any firmware?

 

thanks
