We are an animation studio and we have an intranet that constantly needs to move large files (2 GB+) around the network. We have the following config:
Three Netgear 24 port unmanaged switches. Switch 1 connected to Switch 2 connected to Switch 3 and Switch 3 connected to router. There is a NAS connected to Switch 2.
50 PC's connected to the various switches. 20 workstations and 30 render nodes.
Things work smooth till we send a render job. When we do this, around 30 machines attempt to copy the same file from the NAS at once and the network slows to a crawl.
Managed switches are out of the budget. Upgrading to two 48 port unmanaged stacked switches might be feasible.
I have the following questions:
- Is the way I have connected the switches incorrect? Should Switch 1 and Switch 2 both connect to Switch 3?
- Will moving to two 48 port stacked unmanaged switches relieve this congestion?
- Do 100 Mbps devices on the switches affect the GB connectivity of other devices on the GB switch?
- Is there a way to break up the network. Say have 20 PC's, one NAS on one switch and 20 PC's, a second NAS on the other switch just in case the NAS is the bottleneck. In this case, should I connect both switches to the router? Will they still be able to see each other? The router is a standard router supplied by ISP.
- Is the bandwidth simply not enough for this kind of work?
Thanks for the help. This network stuff is really confusing...
