Windows Server Virtualization

By NetstairComm ·
can any one please be very specific about how much storage is required for virtulized server and how can affect if hard drive storage is not enough on PDC?
what kind of system symtoms would I get?

I am not sure this is helpful but here it goes, assuming small business with 5 Servers 51 users on a Full T1

1 PDC Primary Domain Controller

1 2007 Exchange Mail Server

1 MS-SQL 2008 Server

1 MS Report Server

1 IIS 6.0 Server
5 Domains

All Virtualized.
I hope that the info provided above are helpful.

Is this a homework question of some sort?

by robo_dev In reply to Windows Server Virtualiza ...

The fact that 51 users are sharing a T1 connection has little to do with how much disk space is needed.

Also, a full T1 does not give 10Gb down and 1.5 Gb up (note that GB means Giga BYTE and Gb means Giga bit.... you measure bandwidth in bits and storage in bytes).

A full T1 provides 1.544 Mb/s up and down. So whoever wrote the question has no clue about networking.

The amount of free space on a drive is not very relevant, as you have not stated how big each drive is to begin with.

Is this scenario assuming Windows 2008 Hyper-V or VMWare?

Virtualized Window Server 2003

It is very sad when a pro responds with such an answer.
No offense
"My Grandmother used to say if you answer a question with attitude it means you are not sure your answer is correct"
I thought the forum means post a question and expect an answer We all are learning here no matter how much years of experience we have just remember that technology is unpredictable today works tomorrow it does not.
The reason I provided the information about T1 it was because I did not know that was helpful mentioning. The issue is very simple virtualized servers 2003 is interrupting active directory and acting rare with DNS (not resolving [forward/reverse] zones properly).
Again have you experience the same issue with virtualized servers where PDC Primary Domain controller does not have enough (Hard drive) space not even for window swapping.
I hope this time my questions (which is not a home work) is clear.

BTW Thank you for the tips (GB vs Gb) and (1.5mb vs 1.5BG).

If you don't know that a T1 has NOTHING to do with STORAGE on a system you are in the wrong profession.

Why don't you go play in another sandbox; we don't like spoiled brats here.

What robo_dev stated was correct, as well as CG IT. If you start with minimum specs, you get minimum results. 800MB free on a server is not a lot of space. I'd be increasing that virtual disk's space.

I'm with Robo Dev here. If you work with this you ought to know

by CG IT In reply to Windows Server Virtualiza ...

how can you expect to work on virtualized servers if you don't know anything about them?

but virtualized or not, the operating system contained in a virtualized instance operates the same way as in a non virtualized setting. Physcial memory allocated to a virtual instance is based upon available physical memory. Virtual hdd sizes are based upon available physical hdds. If the virtual instance doesn't have the recommended or even the minimum requirements for the operating system to function, the virtualized server will not run right. And you have to realize that the virtual instances are running under an operating system that isn't virtualized and that operating system has to have the minimum physical resources to run as well.

So take a look at the DC you outlined and find where the problem might be based upon the minimum and recommended hardware requirements of the operating system. If you use minimum requirements, both on the physical server and operating system as well as virtual instances that run on it, have to expect that they aren't going to operate very well.

If you don't know what the minimum requirements for Windows based computers/servers to operate, then that circles back to, "if you work with this, you ought to know".

I'll give you a hint, what happens to a computer [or server] if the amount of free space on a hdd gets to low?

Virtualized window 2003 Servers

by NetstairComm In reply to I'm with Robo Dev here. I ...

Thank you for reply
The plan is replacing existing PDC with RAID 5 with a lot more storage and more RAM but first
we are trying to isolate the issues we are having with active directory interruption and DNS (forward/reverse) zone intermittent right after virtualized servers.
If the virtualization research we are working on gives us the clue or find the solutions then we go ahead as planned.
I am very sorry if I caused any problem by not preparing my questions they way you guy expect and maybe you are right about nonrelated information but believe me most of the time it helps a little.
I thought that by providing as much (related and unrelated) information would make it easier for all of you networking professionals to provide a better answer, as I mentioned before technology is very unpredictable and I could be wrong but what works for one it does not work for others I know that for experience lots of the times is because of hardware is not fully compatible or what it so called lemon hardware.

And again my apology

Thanks again guys.

well all I can say is the Windows Server system requirements

by CG IT In reply to Virtualized window 2003 S ...

do not change whether the server is running natively or in a virtual instance. you should meet the recommended system requirements for the server to operate correctly if you can't then at the least, meet the minimum system requirements.

Given that, what you have planned should be apparent that you do not meet the minimum system requirements with the amount of free disk space that can be used for virtual memory.
