Good day,
I have to set a pair of Sun Fire V880 machines, a pair of T3+ storage
arrays and a pair of SG-XSW8-2GB FC switches in the following way
(the idea of the setup being high availability of the data on the T3+s):
[V880]---[fc switch]---[T3+]
| | |
+--------------+ |
| | |
+---------+ | |
| | |
[V880]---[fc switch]---[T3+]
(ASCII art, please use a fixed width font to see drawing correctly)
Each V880 has a pair of X6729A FC HBAs, and each of the X7629A's
connects to a port of a SG-XSW8-2GB switch.
Each T3+ connects to a port of a switch (each array to different switch)
The two T3+s are interconnected in a partner group.
I need to obtain cables for all connections.
The question is, what exactly types of cables do I need?
Here are some thoughts on the subject:
1. T3+ interconnect cable: no variations. Just one type: 530-2843
2. In the specs of the switch(es)
(http://sunsolve.sun.com/handbook_pub/Devices/Fibre_Channel/FIBRE_2GB_FC_Switch_8.html)
I see that all cables are either LC-LC or LC-SC, which makes me think
I need LC on the switch's side. However, notes 3 and 4 on the same page
bother me -- I do not know whether the switches are 370-5211 or 370-5212
3. In the specs of the T3+
(http://sunsolve.sun.com/handbook_pub/Devices/Fibre_Channel/FIBRE_T3_RAID_Ctlr.html#5710)
I see all cables are LC-SC, and there's an SC coupler offered.
Does that mean that I have to use an LC-LC cable to connect a T3 to
a switch, or an LC-SC+coupler+SC-LC? Or I have completely messed up?
4. In the specs of the HBA
(http://sunsolve.sun.com/handbook_pub/Devices/Fibre_Channel/FIBRE_Single_FC_AL.html)
I can see the connector is SC duplex; does that mean I have to use an
SC-LC cable to connect a HBA to a switch?
Any comments, ideas and answers on the setup and the cables
will be greatly appretiated. I will summarize.
Best Regards,
Stoyan Genov
