Information on Upgrade C370 and M160

[spisipati]

Hi All,

Our current IronPort Farm, (supporting 2,500 Mailboxes)

ESA: 2 x C370; 2 x C100V (with ASyncOS 9.1.0)

SMA: 1 x M160 (End-of-Support on 7/31/2017)

Hence we were recommended to C390 and M190.

Recently more 2,000 Mailboxes were added to Exchange. Do the recommendation suitable / sufficient for total 4,500 Mailboxes. If not, could anyone recommend the next level of upgrade.

Thank you.

Regards,

SP

The C390 are ideal for Medium-sized enterprises while the M190 lists up to 1000 users as per the below data sheet.

However, these are rough estimates and would actually depend on the actual email flow and size of emails processed through these boxes.

For accurate analysis, my recommendation would be to reach out to you Sales representatives at Cisco.
