Max storager under Windows Server? |
|
|
What is the overall maximum storage, not just single drive or partition,
that can be connected to a single 2000 Server, 2003 Server, and 2003 Storage
Server?
My company has an appliaction where we would like to put 108TB under a
single servser.
What are some large configs that people have experience with?
thanks, |

Summary:
You can have a max of 2000 volumes (1000 dynamic, 1000 basic). A dynamic
volume (RAID5) may be up to 62TB (includes parity overhead) or 64TB (RAID0).
A basic volume is limited to 2TB (due to disk sector size of 512). So, you
could have 1000 * 62TB + 1000 * 2TB as a theoretical maximum.
Things to think about:
1) As you increase the number of volumes, boot times increase.
2) File size is not really an issue. A 100MB file has approximately the
same overhead of a 100k file. File/Directory count has a cumulative
overhead associated. The overhead is limited to the volume, so more volumes
are generally more performant than fewer volumes but are harder to manage
(the tradeoff).
3) I would imagine that this is a SAN you are connecting up. Win2k3 has a
number of improvements for being SAN friendly that a number of vendors take
advantage of.
If you have a bit more information about how the app interacts w/the storage
(i.e. a few very, very large files; jillions of small files, etc.) we may be
able to provide some better guidance or reference materials.

Thanks for the feedback and the url.
The application will have 4096 files of approx
27GB each.

Cool. So, if the app allows for multiple paths to the files, you could
balance this across multiple volumes. I recommend that you go with a
cluster size of at least 16k.
Other sizing thoughts are:
1) MFT reserve area is 1/8 of the volume. The actual MFT size will likely
be much smaller given the size of the files (MFT size varies with
file/folder count not with file size). If the volume runs low on space, the
MFT reserve will be released. The issue is that this may increase the
chances of fragmenting the MFT. So, there is a balance here that you need
to be aware of.
2) The Windows file cache caches 'pages' of files, not so much the file
itself. So, even though you would be unlikely to be able to cache a full
file, the more RAM you have the better your perf will be (more pages). The
file cache available (conservative estimate) will be TotalRAM-256MB (allows
for Registry cache, driver cache, basic AV configuration, etc.). AV/Backup
software may eat into this an additional 50-->500MB depending on
configuration and version.
