SATA PCI Adapter That Uses Matrix Storage Manager?

Does anyone make a PCI adapter that supports at least two eSATA ports with
port multipliers, and uses the Intel Matrix Storage manager software for
RAID functions?

I would think that would only be something from Intel itself.

Probably, and that's why I am asking the question on the Intel newsgroup. :)

All of their SAS & SATA raid controller cards use LSI Logic ROC parts (which
don't appear to support the Intel MSM kit)...

Yes, I was noticing the same. This is why I asked the question, since
there might be some older RAID card they discontinued that used the Intel
chipsets and Matrix Storage Manager drivers.

I would doubt it that Intel would sell PCIe cards or even chipsets for
them. Besides, Intel's RAID is done through their CPU's, it's a fake-RAID.

IIRC that is firmware RAID, there is no real RAID hardware involved. It also
results (for RAID5) in every data write which is not a full size perfectly
aligned chuck generating two reads and two writes, each of which go on the
system memory via PCI bus. If you don't have the ability to control writes you
may get better performance writing the data once to a RAID box on eSATA
connection. That moves the overhead off the PCI and system memory bus.

Just a thought, no idea how firm your need to use that storage manager mat be.

I am using these SATA drives for backups. It is great to dedicate a volume
to staging backups, and make that volume a RAID 1. Periodically you can
remove one of the two drives in the RAID 1 pair and put it off site for long
term backup storage. You then insert a replacement drive and it
automatically rebuilds.

The advantage of doing things this way using a non-hardware RAID is that
each drive in the RAID 1 pair can be read by virtually any JBOD SATA
controller. You aren't tied into any proprietary controller dependency.
For doing a recovery from backup, that's very valuable.
