Max FC ports cx4-120
confused from the whitepaper " EMC clariion best practices for performance and availability release 29.0 firmware update applied best practice"
page no 34 .. table 6
it says that max fibre channel ports /SP for cx4-120 is 12..
ok.. now..
CX4-120 uses able ULTRA FLEX i/o modules are 3/SP
slot 0 = 4 fc ports ( port 1 cannt use) 0 for backend , 1 cannt use and 2,3 for FC ports
slot 1 = 4 port fc card (optional)
slot2 = 4 port fc card (optional)
now total comes to 10 front end ports..
(above) am i right ?
now how come this document shows as 12 front end ports per SP ?
please help me understand or is that typo ?

Table 6 is incorrect, and incorrectly labeled, "Per SP". For a CX4-120 front-end data ports per SP: 2 or 6 Fibre Channel, 2 or 4 iSCSI.
A correction will be applied in the EMC CLARiiON Best Practices for Performance and Availability, FLARE Revision 30.0, which should be available shortly on Powerlink.

Nanda,
I think the 12 FE port limit is an Array limit and not an SP limit, s oi would assume a typo....
Considering the CX4-120 can only have a maximum of 3 modules installed.
For a CX4-120 the base config is as follows
4 port ultraflex module in slot 0 (this is configured as a 1x BE and 2 x FE out of the factory).
2 port iSCSI module in slot 1
If you install another 4 port ultraflex module into slot 2 and configure it with 4 FE ports the config would be -
4 port ultraflex module in slot 0 (this is configured as a 1x BE and 2 x FE out of the factory).
2 port iSCSI module in slot 1
4 port ultraflex module in slot 2 (configured with 4 FE ports)
This would give you 1 BE port, 6 FE ports and 2 iSCSI ports per SP.
The array as a whole would have
2 BE ports
4 iSCSI ports
12 FE ports

That particular table seems incorrect to me. If you look at the CX4-480 Hardware and Operation Overview on page 11 the table lists the max FE ports per SP. WIth the base 4 FE ports you can add one more FE FC module for a total of 8 FE ports per SP or 16 total FE ports for the array.

So that means that FLARE 30 is just about out? I hope so, I have a CX4-480 that I am installing in a couple of weeks and would really like to use thick storage pools on it to meet my design needs.
