Factors that Affect Server Storage Capacity | 3G Factors that Affect Server Storage Capacity | Server Storage Optimization

Server Storage Optimization Factor

Operating system files:
 Minimum  15 GB.
To provide space for  future service packs, optional components and other items, plan for an additional 3 GB to 5 GB for the operating system volume. A Windows Server installation can require even more space for temporary files.

Page file:

By default for smaller servers, 1.5 times the amount of RAM.

For servers that have hundreds of gigabytes of memory, you might be able to eliminate the page file; otherwise, the page file might be limited because of space constraints (available disk capacity). The benefit of a page file of larger than 50 GB is unclear.

Memory dump:

Depend on the memory dump file option which you have chosen, use an amount as large as the physical memory 1 MB +.

On servers that have very large amounts of memory, full memory dumps become intractable because of the time that is required to transfer, create and analyze the dump file.

Applications:

According to the application.
Ex. applications include backup and disk quota software, optional components and  database applications.

Log files: 

According to the applications that create the log file.
Some applications let you configure a maximum logfile size. You must make sure that you have enough free space to store the log files.

Data layout and redundancy:

Varies depending on cost, performance,availability, reliability,  and power goals

Shadow copies:

10 percent of the volume, by default, but we recommend increasing this size based on frequency of snapshots and rate of disk data updates.
