RAM and Hard Disk Requirements

The following are requirements for each StorNext mount.

• Client Memory - StorNext requires 512 MB of RAM minimum.

• Client Hard Disk - StorNext requires 200 MB of hard disk space for binaries, documentation, 

configuration, and log files.

• Server Memory - For the first two file systems, a minimum of 512 MB of RAM for each file 

system. Each subsequent file system (up to eight total) either passive or active, must have an 
additional 256 MB of RAM minimum.

• Server Hard Disk - Depending on file system activity, StorNext binaries, documentation, 

configuration, and log files require up to 30 GB of local hard disk space. An additional 2GB of 
hard disk space is required per 1 million managed files.

2TB LUN Requirements

StorNext supports LUNs larger than 2TB. The level of support for this feature varies, depending on 
the operating system you are using:

• Full support for LUNs larger than 2TB

• Full support for LUNs larger than 2TB, with a specific label type required

• Support for only the first 2TB for LUNs larger than 2TB

• No support for LUNs larger than 2TB

Label Types

The type of label you use determines whether your system supports LUNs larger than 2TB. Even if 
your operating system provides support for LUNs larger than 2TB, you cannot use this feature if you 
apply the incorrect label type. 

There are three label types:

• VTOC

• EFI

• sVTOC (or short VTOC)

Generally speaking, the VTOC label is for LUNs less than 2TB, while the EFI and sVTOC labels are 
used for LUNs greater than 2TB. However, in many cases, EFI labels can also be used for LUNs less 
than 2TB.

The following table summarizes the operating system levels for the possible LUN sizes, the level of 
support, and the type of label you should use for the LUN size you want to use. Where there are 
multiple label types listed, the preferred label type is listed first.
