PCI Card Recommendations?


Recommended Posts

I would like to add a storage device to my WHS but need help to find appropriate PCI Card. I purchased a Sans Digital Tower RAID TR4M (4 Bay Sata to eSata) storage unit. It came with a PCI-e card for installation giving a single eSata plugin. The problem I have is my Server (details below) does not have a PCI-e slot on the motherboard. I have an existing eSata plugin (single adapter plugin that is directly plugged into one of the motherboard’s available Sata). When I use this eSata the system only recognizes the HDD in drive 1 of the TR4M.


I contacted Sans Digital and they sent the following e-mail:


Thanks for purchasing our product.

1) The unit is a JBOD enclosure; you can connect the unit directly to an

eSATA port as long as it supports port multiplier.If your host eSATA

port does support PM, then the drives in the unit will show up as

individual disks. No RAID function will be available.

2) Yes, if you want to use any RAID function, you need to install the

PCIe x1 bundled card (Sil3132).




Question (finally)


Any recommendations on a PCI card that offers port multiplier? Is a PCI-x card an option?


Thanks for any recommendations (Sorry this is so long)

Do you have something plugged into the PCI-E slot you show in the description for the motherboard?

It's like an A+ certification course around here, eh? B)


Yes, apparently you can plug an x1 device into an x16 slot and it will work fine.

Not so fast on trying to use your PCIe x16 slot. While a PCIe 1x card should work according to the spec, a lot of motherboard manufactures hard-wired these slots for graphics-only, especially on these older boards. It's worth a shot, but if you find you still need a PCI card, I've had good luck with Newegg's Rosewill brand. Added this card to a couple of older PCs for backups.


Rosewill RC-220 PCI eSATA


Hope this helps!

FYI, http://www.sansdigital.com/community/823.html


It could be that the ESATA port in not port multiplier aware. Like the EX48x HP boxes, there is a ESATA connector on the box but it can only see 1 drive. Try and figure out what chipset you have and see if you fall into this issue.


Or as suggested, get yourself a replacement card, you can find many under $18

Thanks for your reply... The PCIe x 16 slot has a graphics card in it. I only have PCI slots available. Does the Rosewell RC-220 support Port Multiplier?

Yes, it is multilane/port multiplier compatible. It used to be bundled with some of the Rosewill multi-bay SATA enclosures.

Specs say it is generation 1 Sata 1.5 GB/S. I don't know if you care but I thought I would point it out.
