It will will all depend on your controller of choice and what bios.

Thanks, I'm using the dual channel wide-ultra scsi-3 controller that came with the Proliant 800 and am not sure yet whether the bios has been upgraded since it was purchased.

Here is a link to all the drivers and updates you will need... just choose your O/S:

What Prashant is pointing to is that the spec for the 800 shows the largest drive supported is a 36GB Non Hot Plug.

ok, thanks. one more question, can i do raid with the dual channel scsi3 controller or do i need to get a smart array controller card?

Re: scsi drive compatibility

Depending on your O/S, you could do a "Software based RAID" using just the SCSI controller. There are drawbacks to doing this as the O/S has to compute all the disk writes to the disk itself. This computation uses resources suptracting from the processing power of the server.

When you use a Smart Array Controller (like a SmartArray 3200 Controller) you create a "Hardware based RAID". This method removes the need for the processors to much else but tell the controller to write the data.

When you use a Hardware based RAID, you gain the advantage of array acceleration using a separate cache for data read and write. You have a separate processor for data read and write and you have the major advantage of "Hot Spares". There are many other features to look at and measure vs. the costs.

I mention the SmartArray 3200 Controller for compatability sake. They are discontinued from production, but you can find them from Part Stores.

I don't see the SmartArray 3200 Controller on the QuickSpecs controller list. Can I use it in the Proliant 800 PII (6/400) server? Also, I see that it's an Ultra2 SCSI controller. Does this mean I need to get Ultra 2 SCSI hard drives?

David:

You can use a number of controllers in this server, I only mentioned the 3200 series because they are readily available and inexpensive.

You could install a SmartArray 4200 or 5300 series controller in the ProLiant 800 PII system.

No you would not have to purchase Ultra2 drives, these drives are backwards compatable.
