StorNext File System and Storage Manager Installation Guide 11
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 - S torNext 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 p assive 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 dete rmines 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.
