A1000 Disks
Hi, I have an A1000 Storedge Raid, currently fully populated with 36G disks. I thought this was the maximum disk size the chasis would take, however upon reading the hardware specification of the A1000 at:
http://sunsolve.sun.com/handbook_private/Systems/A1000/spec.html
It states I can run 73.4G disks.
However, the document StorEdge A1000 Storage Arrays, Just the Facts states that the maximum disk size is 36G.
http://www.sunsite.ualberta.ca/Sun_Resources/Just_The_Facts/A1000-JTF.ps
I would like to upgrade the disks to 73G, but dont want to purchase 12 disks that won't work.
Can anyone please confirm?
Thanks in advance

That model array first became Generally Available (GA) in 1998.
I think that if you glance inside that JTF document,
you will see it is dated from that era (and never updated since that time).
The array was discontinued in 2004.

Sun does not (usually) go backward to update documentation
on discontinued products (few manufacturers ever do).
The info in the SSH would be your best chance on whatever info is the "latest" info.
The SSH did not exist as a web resource in 1998.
It came to life, circa 2002.
Perhaps others will join this thread and describe their direct experience with the A1000.

Hello,
acccording to the [url=http://sunsolve.sun.com/handbook_pub/Systems/A1000/components.html#Disks][ b]Full Components List[/url] of the A1000, even 146.8GB are supported/qualified !
Please keep in mind that each disk requires a "barrier plate" for proper cooling.

Hi, thanks for the replies.
From the full components list, the 73 and 146G disks require a different barrier plate to the ?36Gb disks. As I have 36G disks already in, I would like to just source the disks and use the existing barrier plates.
Otherwise I am forced to buy the complete Sun product with SPUD bracket and barrier plate, at a considerably higher price, when all I want to do is replace the disks.
Is the specified barrier plate essential and unique to particular drive spec's, or are they a general item, allowing me to reuse those I already have?
Thanks again

Dave,
I can't help with that question.
I don't know why there are as many plates as there happen to be.
Perhaps others have some insight.
I've never had occasion to examine any of the plates, up close.
I can only guess that maybe it's got to do with spacing of mounting holes,
or whatever ...
I just don't know.
The RoHS plates will have new numbers, simply because they are RoHS compliant.
No more, no less.

Maybe a dumb question to ask but I'd like to simulate a SAN for 2 hosts. Can I hook both hosts to a single A1000 via the SCSI connectors ?
I am experimenting with containers with Solaris10. I don't want to mount the disks at the same time but I would like to have the disk visible to each host.
