[f-nsp] foundry-nsp Digest, Vol 70, Issue 10

[Lazuardi Nasution]

Hi Samit,

I think you cannot use ServerIronXL for 100K session/sec L4 traffic.
It only can hold about 19K session/sec L4 traffic. I suggest you to
use ServerIron 350. I found following MSRP on the Internet.

SI350 U$33K
J-B4Gx US$7.7K
J-B16GC US$6.05K

Best regards,
