Netgear SC101 SAN
-
I've often pointed out that the entire "guts" of the SC101 are nothing but a tiny NIC board that has a PATA controller added to it. There is almost zero logic in the system. It's a 100Mb/s Ethernet NIC (single port) with two PATA ports (or maybe only one, now that I think about it) with just enough basic logic to encapsulate ATA calls into the ZSAN protocol and put that raw onto the network (no security) via whatever IP address DHCP assigns. That's it. No CPU, no cache, no RAID logic, no SMART detection, no alert lights, no network settings, nothing.

Here is the slightly modified SC101T. Different housing and look, same basics. The SATA and GigE upgrades were significant, but left all of the fundamental issues intact.

I had an SC101 at one point.

I kept it as it was such a total disaster yet the best piece of teaching equipment that I ever found.

Why are we calling them just a SAN when they are a NAS on top of the SAN too.. just like the NetApp NAS devices (which I hate).

There is no NAS at all. It's pure SAN. Not a unified device, that was the point. This is one of the rare pure SANs in the SOHO / SMB market (along with Buffalo and Drobo products.) No NAS on top of the SAN here.

Correct me if I am wrong, but @scottalanmiller calls anything that does iSCSI / block level only a SAN....
A NAS is something that does NFS / Samba / etc.

Almost any NAS can do iSCSI a SAN is simplier than a NAS..

That's correct. And something Unified Storage if it does both.
Unified Storage: ReadyNAS, Synology, QNAP, Netapp
SAN Only: Drobo B Series, SC101
NAS Only: Exablox -

Exactly, but a few scale outs don't because of the scale out aspect.
