Sun T3+ interconnect cables

Hello,

Having 2 Sun T3+ I would like to get hold of some interconnect cables. For
this reason I'd be interested to find out what exactly is behind of the
cover of those DB9 cables. Is it fibre cables or just null modem?

Thanks.

I hadn't looked into the T3 deeply, but from what I've seen of them,
its just fiber-channel using copper interconnects. The copper cabling
standard for fiber-channel is a pair of balanced signal over twinax on DB9
connectors. Used by many vendors (ie. NetApp) before the switch to the
HSSDC connectors for copper interconnects, while other vendors stuck
only with fiber connects, since copper only did the 2.125Gbps, while
fiber is now doing the 8Gbs speeds...

There can be some passive circuitry in the hoods to compensate for
some of the high-frequency loss on the copper. But they do not do a
fiber to copper conversion. There is standards defined for copper
interconnects, and driver chips and all that. I've got a fiber-channel
switch even that has copper DB9 inserts that look like GBICs as well
as standard fiber GBICs for interconnecting many different kinds.

You should be able to easily find DB9 fiber-channel interconnects that
aren't Sun's on eBay. It looks like the T3s use DB9 on both ends, so
make sure to avoid the HSSDC to DB9 ones that are more common.

No guarantees that these work on the Sun T3, or are long enough for
you, but if they are all doing stock fiber-channel, this should work.

The cables are (or at least were) available from Sun:

#530-2843 FRU,LOOP CABLE,LONG,T3 FRU, LOOP CABLE,LONG Sun StorEdge T3

List price is: $75.00

Depending on your discount level, you should pay a bit less than that.
