We need to pull SCSI hard drives from voicemail systems at work. They are Seagate Cheetah 15K RPM drives. Only one drive exists in each system.

So what we want to do is ghost them. The model we have is the ST373455LC.

It is a Ultra320 SCSI drive with an 80-pins connector. We are trying to make this fit into a Dell Optiplex GX620. It has a PCI and a PCI X16 connector available.

From what I gather, I can find PCI X4 adapter and I'd need a 68 to 80-pins adapter. I don't know if PCI X4 is compatible with the X16 we got.

Do you boot from this drive?

Yeah, it is the sole drive in the system. This is a Nortel CallPilot 600R. Basically, an HP server running a Nortel proprietary voice mail server application.

Be careful with trying the PCI-X slot. I tried the same thing on an HP Desktop and the PCI-X SATA controller we were testing would not work in either the x4 or x16 slot. Worked fine on a OTF ASUS board though.

A bit off topic, what did you guys do for building out your own SAN? I am looking into SANs and thinking about building our own...

So x1, x4 and x16 are not compatible? Looking at the connectors, it seemed like x4 would work in a x16 slot.

It SHOULD, there's something in the HP's that kept it from working though. It worked fine on an ASUS MB, both in the 16x and 4x slots. I'm just saying be careful.

Opensolaris on commodity hardware.

1 x Intel Quad-Core Xeon E5405 / 2 GHz ( 1333 MHz ) - LGA771 Socket -
1 x SUPERMICRO X7DWE
2 x Intel RAID Controller SASUC8I
8 GB 4 x 2 GB Memory
1 x Supermicro AOC-SIMLP-3+
2 x Transcend 2.5" Solid State 64 GB -
2 x FUJITSU Mobile MHZ2160BJ - 2.5" 160 GB
1 x QLogic QLE2562 - PCI Express 2.0 8Gb Fibre Channel HBA
1 x Network adapter - PCI Express x4 - 4 Port Gigabit
1 x Supermicro SC846 E2-R900B
24 x 2TB Seagate Barracuda 7200RPM Sata

Plus some misc. parts and cables to put everything together. Comes in around $11,000 for 48 Raw TB of Storage. We're putting two of this model in place for D2D backups and archival storage. We built another one with 15k SAS drives for one of our departments that needed faster disk access and throughput. It was a bit more, but still MUCH less than any of the proprietary solutions out there.

A few nice things about the setup:

Opensolaris, zpools, and zfs are the bomb. We have incredible flexiblity in how we can present the storage to our network, zfs is FAST, there's no zero write hole issue to worry about, and dedupe is around the corner.

We've built a lot of redundancy into it, the second raid controller is redundant to the first through the chassis backplane, all the drives are hot swap, 2 drives for an OS mirror, and 2 drives for the zfs log mirror. About the only real worry right now is the MB/CPU, but we have spare parts on hand and I can swap them out in about 20 minutes if I need to. Which brings up another nice thing, I can keep spare drives on hand to swap in at a moments notice, unlike some other storage vendors...

The SAS unit is very fast, I was getting iop numbers equal to the enterprise stuff we have.Using the built in benchmark tool that Opensolaris has, I was getting 22000 iops over 14 drives using their database simulation and approx. 270MB/sec read/write using the file server test. Benchmarking the SATA unit next week.

The drawback to opensolaris is you better be able to manage it, there's no pretty gui or webpage, it's all command line, but if you're familiar with linux then you'll be OK.

It IS OS agnostic, so windows server will work, however we found that we lost about 30% of the performance in testing.

Cool.

CLI stuff is absolutely no prob for us. 90% of our infrastructure is now running open source in one way or another. We typically manage all of or servers through ssh.

The only windows stuff we use are domain controllers now. Active Directory is pretty much it.

The only real issue we've run into so far is that the kernel mode cifs server and idmap have issues with AD forests that have multiple domains. Other than that it's been fantastic.

That's funny, we have run into Samba issues with our AD forest and multiple domains.

I am actually in the process of migrating a large amount of our users onto a single domain spanning multiple sites with multi-homed samba servers.

It's pretty much the same issue afaik. There are ways around it using vms, but it's kind of ugly to do it that way. Posts on the Opensolaris site indicate that this is a priority issue for Sun and they're working on getting the native cifs server to function in AD like a native windows server.

Our main goal with a San is for our Linux servers. The main one being our Cluster running Zimbra.

Currently we have 4TB internal SAS (0+1). As our storage is growing, we are seeing more and more the need for a San.

We started offering hosted mailboxes on our Zimbra setup (plus BES) to small businesses and the response has been awesome. In the past year we double the accounts on the system and have not lost a single customer. The referrals are amazing.

These would work very well for you then. Add in a fiber switch, use NDMP, and you're set.
