Hi Reza,

Thanks. So Is there any model more than 7 slots from 6800 series?!

another question, there is a difference between X2-10GB-SR= and SFP-10G-SR= because I want to replace the WS-X6816-10G-2T card with C6800-32P10G-XL which can carry 32 ports 10G with One card so I can save one slot! can I do that?

Thanks again

Mohammad Saeed

Hi Mohammad,

6807 is the larger chassis you can get on the 6800 series.  As for 16 port 10Gig vs 32 port 10Gig, you can defiantly use the 32 port 10gig module to solve the issue if not having enough slots for all your 10Gig interfaces. Also, you can enable VSS on the 6800 series to give you the redundancy you need without using HSRP/VRRP, etc..

Hi Reza,

Thanks, but 16port 10Gig uses Pluggable transceivers X2-10GB-SR= and 32port 10Gig uses Pluggable transceivers  SFP-10G-SR=?! is there any difference between them? or both them the same!

Thanks,

Mohammad,

You need the 16 port 10Gig SFP+ or the 32 port 10Gig SFP+

Two models: C6800-16P10G, a 16-port 10-Gigabit Ethernet Fiber Module with DFC4 (Figure 2), and C6800-16P10G-XL, a16-port 10-Gigabit Ethernet Fiber Module with DFC4XL

Two models: C6800-32P10G, a 32-port 10-Gigabit Ethernet Fiber Module with DFC4 (see Figure 1), and C6800-32P10G-XL, a 32-port 10-Gigabit Ethernet Fiber Module with DFC4XL

Hi Reza,

I mean the difference between  WS-X6816-10G-2T card and C6800-32P10G-XL.

because  WS-X6816-10G-2T uses x2 transceivee. but C6800-32P10G-XL. uses sfp+ is there any differences?

X2 and SFP are different form factors.  On some of these, you CAN get a twinGig adapter to convert an X2 into multiple SFP ports, but I don't think these can be 10G SFP+ (although it may be possible on the newer modules).

Good! but if I need 10 Gig I can use whatever pluggable SFP+ either X2! Am I right? I mean technically I can get 10 Gig with the same performance! 

There shouldn't be a performance difference between SFP+ or X2.  However, check the capability of the line card / chassis backplane - if you have 16 10G ports, make sure the line card plugged into supports what you expect.  Remember, if all ports are 10G running flat out, your total backplane for that line card is 160G, unless it's between servers in the same VLAN connected to the same blade.

(This probably would only happen during backup windows... ?  )

Cisco said in their document i can add high density card with 10 gig 32port for 6807xl , so i think it will work! actually i want to connect stacking edge switches with these ports mot servers

Hi Mohammad,

Don't use any module with X2 transceivers.  They are big, bulky, older and become lose rather easily.  Just use the part numbers I provided you.  Both modules use SFP+. X2 is outdated and being replaced by SFP+.
