SAS SFF disk with E200i controller

Hi,

We have a proliant ML350 G5 with SAS LFF drive bay, controlled by an RAID E200i controller.
I have 2 SAS SFF disks (non hot swappable).
Is there any way to connect one or both of these disks with this server? E.g. I've raid that there are 2 ports on the E200i controller. Can I connect one of these drives directly to it?
If it is possible to connect them, I'd still have to find a way to fit the disks mechanically.

Re: SAS SFF disk with E200i controller

Hi,

Thanks for your answer, but I'm still not clear about it.
The Proliant ML350 G5 server comes in 2 editions : one with a 6-slot bay for 3.5" SAS drives (LFF = large form factor), or with a 8-slot bay for 2.5" drives (SFF = small).
We have the LFF edition, and I would like to use one or both my SFF drives that I have lying around. But as your link also points out : its either SFF or LFF.
But I was hoping because the RAID controller has 2 ports, I could link a drive to the unused port...

Re: SAS SFF disk with E200i controller

Great! Could you tell me how? What cabling or adapter that I need?

Re: SAS SFF disk with E200i controller

Bump.

Hi, I still do not know how to attach my spare SAS drives to the E200i controller. Can anyone help me?

Officially this is not supported so you will be on your own if you do this.

You need to convert the SFF disks to LFF using something like this. http://www.provantage.com/cru-dataport-5220-0000-02~7CRUD114.htm (search some more you may find a cheaper bracket adapter)
Now you have a 3.5 "bare" disk unit, you still need the LFF slot bracket to put the disk in the LFF slot. Check if you can use the slot fillers as LFF brackets. (or are they useless plastic fillers?)

Re: SAS SFF disk with E200i controller

Again, you are on your own if you do this, it is not a supportable disk configuration.

If you are thinking about putting the SFF drives in the removable media bays (at the top) you will have to use one of the E200 connections. There are two E200 cables and each cable is a 4-port cable that conencts to 4 drives at the drive cage. Unplug the one that points to the empty slots. Look at midde of page 65 of http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c00708990/c00708990.pdf one cable is for drives 1-4 the other for drives 5-8. This is for 8 SFF drives, the LFF is probably similar.

Then you would need a fan-out cable from the 4-port connector on the E200 to the 1-port connector on the drives. Each drive would need its own power connector as well.

Search online for "SFF-8484 to SFF-8482", I bought one last year for $30.

Re: SAS SFF disk with E200i controller

Hi,

Thanks for your reply and suggestions!
Our LFF bay (6-slot) is completely occupied: 2x 72GB drive, 2x 145GB drive, 2x 300GB drive.
There are no fixed drives in the removable drive bays.

The 2 spare SFF 300GB drives that I have are 492620-B21.

I understand that there must be empty slot in the LFF to be able to use fixed drives in the removable drives bays.

What would now be the easiest way to use them in our server?
I am thinking : remove the 2x 72GB hotswap drives, and use their casing for the SFF drives with the adapter that you proposed. Will this work? Are the connections the same?

Thanks again!
Thomas.

Re: SAS SFF disk with E200i controller

Replacing the 72GB drives would be the way to go. As for the connectors, the description of this bracket claims that it is "designed specifically...backplanes". It mentions backplanes so I would assume that the connectors of the 2.5" disk/3.5" bracket would line-up with the connectors of the 3.5" slot. To verify it, you need to compare the 2.5"disk/3.5" bracket with a full size 3.5" SAS or SATA disk and see if the connectors are all the way on one side and at the bottom (or top) as shown in the bracket picture. The connector type is definitely the same, it is the position of it you need to check. To me it looks like it will fit in the slot if you use the 72GB slot bracket.

Re: SAS SFF disk with E200i controller

Hi,

I also think this is the best idea. I will try to determine if the SFF disk in the adapter, will fit in the housing of my 72GB LFF hotswap disk.
I'll have to compare my 72GB disk that I remove from the housing, with the picture on the website.
(I found a high res on http://www.cru-dataport.com/slideshow.php?dir=//Mounting-Kits//&sel=5)

Don't suppose you know a better way to check compatibility than looking at a picture :-)

Thanks!
Thomas.

Re: SAS SFF disk with E200i controller

Unfortunately you have to rely on the picture comparison. Usually the bracket manufacturers take that into account. The ML LFF drive bay bracket might have its own connector adapter built in as well.

Look at this WD web site

http://www.westerndigital.com/en/products/products.asp?DriveID=495

This is a **3.5-inch (backplane-ready)** drive but it really is a 2.5" drive in a bracket. Note that the drive is in the middle of the bracket however it has a connector adapter that positions its external connector at the bottom(top) and to the side. Look at the 3rd picture.

If you click on the **3.5-inch (SATA cable connect)** drive you will see that the connector in the middle. This is "cable connect" not backplane.

I am not trying to make you buy that bracket. I have no idea who that web site is, I just happened to find their picture. You can search yourself for a bracket and maybe find a cheaper one.

Re: SAS SFF disk with E200i controller

Hi,

The new adapter that you propose, is for SATA in my opinion (not SAS).
The connectors are not the same as on my SAS drives. I've attached pictures of my LFF and SFF drives. (btw I made a mistake, I thought that the SFF was not hotswappable but it is, I didn't take it out of the packaging).
So I think your first proposal (CRU-DataPort Hard Drive Mounting Kit) still is the way to go.
The connectors of the SFF and LFF seem to be the same (see pics), but the LFF has an extra 4 pin connector that the SFF doesn't have. What do you think?

Re: SAS SFF disk with E200i controller

I was not proposing a new adapter. The WD pictures were for illustartion only. The SAS and SATA cabling and connectors are identical.

I don't see the 4pin connector on the LFF drive. Is it in the center inside the cavity?It is probably a jumper block to selct 1.5GB vs. 3GB and most likely it is not used. Check inside the drive bay to see if there is a 4-pin receptacle that the 4 pins from the drive plug in to.

Re: SAS SFF disk with E200i controller

Hi,

Indeed it seems to be a jumper block.
I'll take my flashlight and double check for a connector in the drive bay.
In the mean time, I'll try to order the adapter at the provantage store.

I'll let you know!

Thomas.
