Maximum vDisk file size supported by Tintri

Applies To




Tintri OS


Bug(s): N/A


Creating a file size greater than the maximum file size generates a report to the client that the file is too large.


Q & A

Q : What is the max vDisk file size supported on Tintri?

A: From Tintri OS(TOS) 4.2, the maximum supported vDisk size is up to 64 TiB. This is documented in the release notes per TOS release. 

Note: Prior to TOS 4.2 the supported file size is just below 16TiB, so one would be able to create a file size of 15.99999TiB.

Note: Depending on the hypervisor used when creating a vDisk, what is reported as Terabyte (TB) is in fact Tebibyte (TiB). For example, this is true with VMware vCenter.




Tebibyte (TiB) is one of the standard units used in the field of data processing and data transmission (along with gibibyte (GiB)mebibyte (MiB)kibibyte (KiB), etc.). Tebibyte, gibibyte, mebibyte, and kibibyte are defined as powers of 2. 1 TiB equals 240 bytes or 1,099,511,627,776 bytes. Tebibyte is closely related to terabyte (TB), which can be a synonym of tebibyte or can refer to 1012 bytes or 1,000,000,000,000 bytes in accordance with International System of Units (SI).

Terabyte (TB) can have different meanings in different contexts. When referring to computer memory, terabyte is allways a “power of two” - 1,099,511,627,776 bytes, but when measuring hard drive capacity it is often defined as 1,000,000,000,000 bytes. Generally, operating systems calculate disk and file sizes using binary numbers, so a new 5.0 TB drive you've just purchased would be reported by the OS as "4.547 TB" (meaning 4.547 TiB).

This article also provides a Terabyte (TB) to Tebibyte (TiB) and Gigabyte (GB) to Gibibyte (GiB) Converter.

FYI - From OS 4.2, vdisks of up to 64TB can be created. As per the 4.2 release notes:

Tintri OS 4.2 allows vDisks of sizes up to 64TB. Please check your hypervisor's disk size limit for logical
