1. What type of storage are you using.
Penguin x8dtn, 24 1tb disks
Penguin x8dtn, 24 1tb disks
Can find anything about this setup. Do you have specs/a link ?

| 2. What type of disks sata |
Definitely not optimal for the amount of files or the access patterns you describe.

| 3. If using a controller based array, what you optimized for sequential or random operation. |
Sounds like it should be random optimized, but depends on the array or RAID controller and its capabilities whether or not this a selectable.

| 4. Will you mirror on-host or using hardware RAID controller based raid 10. six disks per raid set |
Seems like a reasonable choice.

| 4. What is your storage block size. |

| 64k |

| 5. What is the average size of your writes |
Quote:
| dunno, guess is a few meg. No more than 16m. These are email attachments |
That is the size of the objects not the size of the writes. iostats for the file systems would be good here.

| 6. What is the breakdown of reads/writes not sure |
This might be essential information, depends on the pattern, but caching correctly might improve performance drastically.

| 9. How many files per directory do you have ( files includes sub-directories) in the largest directory. |
Quote:
| millions |
This is in all probability your main bottleneck, more file systems or directories with fewer files could improve this.
