We are considering converting several physical edge services boxes running DNS and Syslog, from physical to virtual machines. Someone raised a concern regarding the expected volume of small network packets, likely around 1500 (mostly UDP) packets per second. We're on a gig network.
I've had a number of vendors steer us away from virtuals in the past due to a high volume of network chatter. HP SIM, for example,monitors thousands of servers via SNMP and the vendor will not certify on VM due to potential network congestion.
My questions are:
A) Is there reason to be concerned with provisioning Syslog/DNS on a virtual, knowing that I'll get ~1500 packets/second?
B) Is there a 'rule of thumb' or guideline for "acceptable" volume of small network packets on a VM?
B) Are there any other "gotchas" running Syslog or DNS on a 3.5x VM that anyone is aware of?
Thanks in advance for your assistance!
