is it a "software" raid?

CC4 Upgrade - Summer 2010
oxide54 replied to maestromasada's topic in Network and Classroom Management
it was based on the restriction that this kind of system imposes "it has to be boss" i.e. the cc4 server has to be the forest root, which I don't think your going to solve by swapping the DHCP/DNS services over the forest root is a completely different concept, which means re-install. btw the "go vanilla was a joke" lighten up -

why not save your self some money and go vanilla on both, and you can do things how you want then? -
Students can install software! I can't find where this was set.

if you install XP fresh on a computer and join it to the domain do they still have the permission? at least that way you will know whether its in a GPO or just on the machines, -
We get that a lot, and PS/2 keyboard and mouse stumps them! One said it was because they need more reach on the mouse? How long a lead do you need?

and open source Sweet!!!

Just thought I'd let you know about TreePie. I've been having some problems with certain departments eating a lot of space and treepie has been invaluable in tracking down what space is used where. Basically you give it a directory and it gives you a pie chart of the contents. Showing you which folders contain the most data. Beats right clicking until you find the culprit.

Personally we had more issues with the cages than with the kids. Our school had desks with cages underneath, unfortunately the cage restricted the air flow and caused overheating and failure of a lage number of PSU's. We also found that kids were more likely to try and mess with the inputs and network leads when they know all the wires are buried under the desk and you will have to go downstairs to get a key to open the cage and the whole process will quite conveniently kill half their lesson. We've found with them on the desk open, most of the ICT teachers have now developed the "skill" where they can actually plug a mouse back in with out calling us down! + you can deal with it their and then as you can clearly see what the problem is. I just find the more the hide stuff away the harder it is to find the problem and the more problems occur. But what works for us won't necessarily for the next school.

oh okay, personally i think I'm too much of a control freak for software like that! -
I'm looking for a micro ATX case, something like a cube, and a cheap mobo. To run serato. Capacity for a few Hard disks would be nice, but not essential as I could always use external / serato's min specs aren't horrific but I'm going to need 4gb ram and to run XP on it/ Scratch Live | Serato.com any ideas? Don't want to spend too much.

Seriously WTF are you doing using snapshots in a production enviroment? the only time i ever use it is before a SIMS upgrade, in case I end up with 300 people who can't login in to SIMS. I always always delete the snapshot by the end of the next day.

serious question? what does CC4 give you that you can't do with vanilla? I'm just curious because the last time a messed with RM was when I was in primary school,./ -
duds check your pm

I think I was just nit picking a bit !
-
does it? ESX yes not ESXi the memory foot print is way less than that
-
are you sure about that? what version are you on?

When I started at our place I removed the virtualization and put it all physical. Then slowly virtualized it. Reason being it was a big mess. The previous NM had gone from 5 physical servers each with 2gb ram each to 4 new hosts with 4gb each that ran slower than the old system. The 4 hosts were running 3 different linux distro's with vmware server. ( ESXi wasn't out at the time), The linux os on the hosts was using between 1-2gb of RAM leaving 2gb for the VMs. He had added additional VM's so each VM had less ram than it did on the old system. A host could not mount a lun on the SAN if another host had already mounted it. The existing Windows domain was beyond repair (in a reasonable timescale). So I basically built a new windows domain, on the old physical hardware. Once we had joined each computer to the new domain, and moved the data over, I started virtualizing on the new hardware using ESX. I initially created the VM's on the local datastore (before I had all the data I needed off of the SAN). The DC's were done while school was open. Created new ones and ran them alongside. Configured everything but didn't turn on DHCP. Then when everything was setup disabled DHCP on the old DC's and enabled on the new ones. The exchange server(s) again were done while school was open, you just set up the new server and move the mailboxes. Outlook auto-reconfigures the client for you. SIMS remained as a the whole time VM. I had to shut it down and move hosts quite a few times. This was done in the evening / before school. The file server was done a bit sneakly. I created scripts that disabled the user account. Moved the home folder to the new file server. Change the home folder property of the account, re enabled the account. (the staff I left the script running in the evening) the kids I did when that year group was not in an ICT lesson. The printers was a PITA i used the print queue migration tool from microsoft, and at this point turned off the old server and renamed the new server to the name of the old one, so GPO's still deployed using the same names. At this point I also had to point the home folders back at the old server name, (right click on multiple user accounts in active directory users and computers). The only server I didn't build as a fresh VM was the SIMS server.
-
out of interest ( may I should start a new thread /? ) who keeps their ESX(i) boxes on the same vlan as the VM's?
-
oh okay, cant really comment on iscsi we are using FC. but I noticed I couldn't leave DPM to sync backups every 15 minutes as it was saturating the hosts fc connection especially on the file servers causing them to hang momentarily every 15 minutes.
-
how does this get you more bandwith? surely all your doing by vlaning is logical seperation of the existing bandwidth.
-
How many VM's are these 3 nic's shared between? And what do the VM's do? it might not be the nic that is the bottleneck. adding a 4 port nic will get you "more bandwidth" but will this solve your problem? I can't answer this because you didn't state what it was. bear in mind I'm running 25+ vms (and growing) over 3 hosts.
-
thats a good idea, might nick that one! technically any user's profile that logged on the last time the computer was on would still be on there, if the script operates at startup and not shutdown.
