Out-of-band LAN for backup traffic, lowest end Cisco switch gigabit RJ45 ports, Cisco 29xx support link aggregation?
Posted on 2009-02-08
What's the lowest end gigabit Cisco switch that comes with gigabit network ports (RJ45)?
Any non-chassis (such as 3xxx series) models ? 6xxx & 4xxx models are the chassis
type : we don't want those if possible. Looking for something that's 2U dimension type
(so Alcatel models are fine too as long as they support gigabit)
BTW, can Layer 2 switches namely the 29xx series support link aggregation (ie
2 NIC ports on a server) connects to it & get the bandwidth of 2xGigabit ports?
We have several LANs/VLANs including two DMZs.
We're planning to set up a backup LAN dedicated to central backup traffic (Data
So the central backup server needs a spare NIC port (or would it help if we used
two NIC ports to aggregate them to get faster bandwidth/backup when backing up
from multiple clients concurrently??)
So we'll need a spare NIC port on each client to be backed up, spare switches
(as our current switch is running out of ports) and a firewall? Is the policy for
setting up a backup LAN to connect to DMZ requires a firewall?
if we don't get a firewall (due to budget constraints), any way to perform central
backup of the servers in DMZ? Is it acceptable from security point of view to use
a Cisco Layer 3 switch with ACLs to segregate between the Backup LAN & DMZ
