Network Slow Down in One Classroom
Got my head scratching this has.
One classroom seems to have always suffered from problems, while all the others seem fine.
Hoping that a re-image of PC's over the Summer would help, and initially things look ok, but the main issue re-appeared today. All the machines just seemed to run to a crawl and struggled trying to save files to the network. I'm waiting on some test results of a Fibre Health Check that was done over the summer to see if we have a suspect fibre feeding the room.
This room is looked after by 2 x HP ProCurve 2324 Switches which are unmanaged, so I've never been able to setup a Monitor/Mirror Port and do a bit of packet sniffing.
Now, the upgrades over the summer didn't upgrade these switches (wish I did now), however it has released an old HP ProCurve 4000M Core Switch. So, this evening I've put this in place of the two unmanaged switches in a hope that if the problems persist I can start to track things down a bit.
Now, initally logons on the machines seem 'snappier' but true test will be tomorrow when the kids are back in, but my nagging doubt is this: The 2324 have a much higher bandwidth capacity (approx 9Gbps), where as the old 4000M has only 3.6Gbps, the 2324 are unmanaged but the 4000M is managed, is this really going to be an issue? Is opening the odd Office Document and a bit of web surfing really going to cause that much strain of this old device?
Will report back tomorrow.....
