Max FC ports cx4-120

Jump to solution

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

thanks.. But in that case, howcome cx4-480 also showing 12 fe ports / array ?

I request you open that page and please clarify me..

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.
