Summary<\/h3>\n

We recommend requesting at least 25% more storage space than the size of the files that you’d like to store. <\/strong><\/p>\n

File size can be greatly reduced by compressing your files using an archive format such as .zip, .tar, or .cpio, and file compression is a particularly good idea if you don’t access the contents of those files very often.<\/p>\n

If you’d like more information on determining file size or compressing files, assistance can be provided by the IT Help Center<\/a> or your local IT support organization<\/a>. Also basic instructions for using .zip can also be found online.<\/a><\/p>\n

Technical Details & Background Information for Administrators<\/h3>
<\/p>\n

Content transferred to the Network File Storage\u00a0service is allocated on disk using\u00a0the physical storage requirement, which includes data protection blocks.\u00a0This will be at least 25% greater than the logical storage size reported on a traditional filesystem, which does not report parity\/raid overhead (most desktop operating systems will report storage usage this way). If you store files with average size exceeding 4MB, expect your content to have an overhead requirement of 25-30%. (See background information below for additional details.)<\/p>\n

If you have multiple terabytes, quota allocations for Network File Storage\u00a0\u201cterabytes\u201d are calculated using powers of 2, not base-10 calculation typically used by disk vendors. This is more formally called a\u00a0tebibyte<\/a> and is about 10% larger than a \u201cterabyte:\u201d<\/p>\n
