You are very brave posting this here!!

A what point (no. of users) would you start creating VLAN's on a switch?

My duties stop short of the RJ45 cable Big grin but here's my take on this :

There is no written rule with our equipment (gigabit switch) that states that after an X number of users you have to create a VLAN.

You can have one with as little as 10 users; on the other hand, you can have 24 users directly connected to our 24-port Gigabit switch with little bandwith loss compared to the VLAN option.

There is also the option of cascading ports but we're now deep into the network admin's job Big grin

N228UA, trhe first thing I learnt on my first job after University: there are two reasons to create VLANs, one for security, the second to improve performance by reducing broadcasts.

However, if all the users are linked to the same switch (as your question indicates), there is no possibility to have gain by introducing VLANs (and routing from one VLAN to the other all within the same switch).

The only gain can be made if there are broadcasts in your whole LAN, then you seperate the areas, and performance will be improved globally because broadcasts will not filter from one VLAN to the other.

Today, as the manager of the MIS section of our IT department, I am as far of all this as imaginable.


Now, a question to UTA. How can a server tech support engineer afford to participate in auto races as a hobby?

There should be a redundant toner cartridge enabled on your printer.

Go to "Array Configuration Utility" to see which physical cartridge is failing

What would you suggest as a low-end RAID NAS solution. Something that supports ~ 100GB total capacity, supports NFS and allows hot-swap of individual disks in case of failure.

I have two home networks, one at my home in south Florida, and the other up here in northern Florida.

I want to be able to gain access to my networks from either location, take files from those computers and such; have my computer up here treated like it was down there in that network, and vice versa.

I downloaded VNC but that just simulates the computer I'm trying to access, its not my computer in the other network. Do you know any free software for VPN that would do what I explained above?
Sometimes I go about in pity for myself and all the while a great wind carries me across the sky.

UTA is right, for 24 users there is no point. But if he had 24 other switches chained to his switch, then a VLAN would be handy in some cases.

SInce it could be a serious question I'll give a serious answer.
My tasks are taking care of our Top 100 customers' issues at a level 2 basis, which means I shall (...) not get bothered if their mouse is not working.
My duties come in when the application is mission critical (my customers include CDG and ORY ATC, Airbus, Dassault among others), critical-down or critical-degraded.
If there are no such occurrences than my job consists in monitoring the level 1 foo...er...technicians (read : post foolish threads on the Nonav forum).

It started out when I met people that were racing in the Saxo Cup / Group N / Formula Ford /Formula 3 track categories.

I had an old Alfa 33 16V car that I did not use anymore; by chance it was homologated in the Group N 1.5 to 2.0 liter category, so I stripped the interior, got given an old racing seat/roollcage/safety equipment/etc...

I participated in a few races and I also got the opportunity of trying out the following machines :
- Karting (also in races)
- Group F
- Group FN
- Group A
- Megane Cup car
- Formula Ford 1600
- Formula 3 (Alfa Romeo V6 3000 engine -that rocked)

I haven't raced in along time but am looking to get a used Civic VTEC in the near future Big grin

Thanks for the pointer to the HP ML350 solution. Looking at HP site, I also found the HP ML110 G2. Both the ML110 and the (equivalent) Dell PowerVault 745N use Microsoft Storage Server 2003.

I've never had any experience with Microsoft Storage Server ... have you ? If so any comments ?

Thanks for the help

Quoting N228UA (Reply 14):

UTA is right, for 24 users there is no point. But if he had 24 other switches chained to his switch, then a VLAN would be handy in some cases.

In IT you have to be very accurate in what you say. Maybe the average numbers of users is what was meant in your sentence, but that word wasn't used.. not that average of users per switch is what is measured anyway.

And again:

Quoting N228UA (Reply 14):

I don't see what adding a VLAN would do, unless you have one department scattered on more than one switch, but that wants layer 3 and layer 2 disconnection because of its special operations. Otherwise, to improve performance, you usually want more than two VLANs (which is what you get if you create one, and the rest becoming the default VLAN).

Two mistakes already that would have caused my first boss to correct me bitterly.

UTA - What do you know about tape backups?

I have a 2000 server that has had a DLT tape drive swapped out, new tapes purchased, heads cleaned, and the darn thing will still not back up! Only now it's trickier to troubleshoot - it gets to over half way and then says there is no DLT media available (will have to get the exact text of the error)... grrr!

I think $379 is a bit pricy just to get 4 boxes/network connections on the network.
I like the following from the above URL:
Wafer said: "Interestingly, a number of local phone companies and service providers have expressed interest in bringing fiber into the home and using this product for selling their home networking services."

For those who might not know, MCI is testing FTTP (yes there's supposed to be an extra 'T' in there I forget the EXACT enumeration of it, but basically it's Fiber to premise) out west, and is interested in getting MCO onboard as a primary market. They are talking 50 MBps (yes a big B) for $35/month. Of course I have yet to see this deployed for real, and considering some sources I have read about it indicate a price point of $5,000.00 to deliver FTTP to A house, that's a HUGE investment for MCI to make, then again if they corner Internet VOIP, and entertainment a-la cable/satelite through that reasonably fat pipe (2005 home internet terms in case someone reads this 20 years from now and has a good laugh) it could be a windfall they could recover the cost of with in under 5 years. All I know is if I see it for real, Brighthouse is going to have a problem with me....
