Storage Options

[spamly]

I'm maintaining a legacy application that isn't working too well on our SAN. The problem is that with any zone changes, the servers loose access to their drives. These systems may be around for quite a while and our SAN vendors are reluntant to support their OS version. We'd really like to move them to scsi attached drives. Performance is a concern and we know from experience that local mirrored drives just aren't fast enough.

I need some help with choosing some Sun storage arrays. I'd like to have as few storage arrays as possible. I've been browsing through options on Sun's website:

http://www.sun.com/storage/workgroup/

Requirements:
I've got a total of 4 servers 420's running Solaris 2.6. Each of these servers are fibre connected to our SAN.
- 2 servers which each have a 100 GB SAN drive
- 2 servers which each have a 20 GB SAN drive
All this data has got to move to one or more storage arrays. I am also unable to consolidate any of the servers.

Does anyone other there have any experience with these Sun products? I was looking at getting 4 S1 arrays, but as you can see, 2 of them will hardly be used. Do you have any suggestions?

Thanks!

If you need RAID, SCSI and Sun hardware look at the 33x0 arrays.

If you loose your SAN drives on zoning changes, your i/o timeouts are probably to low. Try to increase them in /etc/system and do a reboot:

set sd:sd_io_time=180
set ssd:ssd_io_time=180

You can check the current config with adb:

root# adb -k
sd_io_time/D
60
ssd_io_time/D
60
$q
root#
