Esata Controller for HP Proliant Ml350 G5

I have a Hp ProLiant ML350 G5.. I am looking to purchase a Esata controller card. So I can attach a external Sata drive for backup purpose. I am having a hard time finding one for the specs of this server.. On the back of the server the following is listed:
PCI Express X4

PCI X x2 64 / 100

PCI x x1 64 / 133

Attached is a pic of the inside of server - Please advise on fastest Esata that I can install.


Thanks

The link you've provided in your comment is to a SATA controller card which doesn't offer eSATA connectivity?

"Koutech IO-PSA421 PCI-X SATA II Controller Card"
See image of rear of card here: http://tinyurl.com/2vnx3sa

This is closer to your needs I think:

I would go with USB 3 instead of eSATA because it offers more flexibility than eSATA.
Very high speed (5GB/sec) with better hot swap capabilities.
I've had issues with external drive cases and hot swap eSATA.

If all you want is backup disk externally,then USB 3 is a better choice.

http://tinyurl.com/2vjptcb will work with my PCI Express X4 slot?  Doesnt look like they match up properly.

Pqm554: I already have the eSata enclosures so I have to stick with the eSata controller.

x1 will work in x4 slots just not the other way around

As for the esata vs usb 3 ,esata just didn't hot swap very well ,if at all.
You had to reboot the server so the card could redetect the drive.

So you saying that it's possible that I would have to reboot server when I am changing external Esata drives on a daily basis??

Yes,been there done that.

To the best of my knowledge the slots are 'downwards compatible' ie: you can put a PCIe x1 card in a PCIe x4 slot
Here are a couple of forums with people discussing this:
http://www.techspot.com/vb/topic131687.html
http://www.tomshardware.co.uk/forum/248741-10-pcie-pcie-slot
It won't fill up the whole slot, but that is allowed for in the PCIe standard. Here is a quote from Wikipedia on the subject:
"A PCIe card will fit into a slot of its physical size or larger"

I'll bow to pgm554's greater experience on the realities of living with hot swap eSATA :-)

pgm554Commented:
The new spec supposedly allows for hot swap,but it depends upon implementation and my experience with hot swap has not be a good one with esata hot swap..

pgm554:

   Which card where you using that this was happening?  Wasnt there a driver update to fix that issue?

joesincCommented:
Maybe purchasing an eSATA controller card and an external storage device from the same manufacturer could help with that kind of problem, but this is all theoretical until you jump in and buy the kit.
The USB3 idea is a good one if the Hot Swap functionality is important for you.

The enclosures I use are the NexStar CX - eSATA / USB 2.0 by Vantec.  They are adapter powered with a On / Off button.. It cant be considered HOT swap if power is turned off prior to exchanging drives?

I am now thinking of using this controller card with my current server.  It's a PCIe X1.. but from what I am now understanding that will still work in my x4 slot.

pgm554Commented:
I've used several including Startech and Vantech with same results.
The BIOS on the card needs to identify the disk on POST and hotswapping just didn't work on the cheap cards.

Hotswap cages from Dell and their controllers allow for hot swap because of the firmware on the controllers,but the cheapies just don't seem to do the job.

On the link to the drive enclosures it states:

Hot-Swappable: Plug & Play Without Rebooting


I also have a call into there tech support.

pgm554Commented:
Probably for the USB connection.
I have a couple of Vantec enclosures and had to reboot using the eSATA connection.
