Quantum 3.5 manual File Systems, Disk Space, Partitioning Local Hard Disks

Table 2 Storage Manager Hardware Requirements

	Chapter 1		Installing StorNext File System and Storage Manager
				Storage Manager System Requirements
File Systems		RAM		Disk Space
1–4*		2 GB		• For application binaries, log files,
				and documentation: up to 30GB
5–8**		4 GB
				(depending on system activity)
				• For support directories: 3 GB per
				million files stored†
				• For metadata: 25GB minimum

*Two CPUs recommended for best performance.

**Two CPUs required for best performance.

†For non-managed file systems, the requirement is 1GB per million files stored.

Note: If a file system uses deduplicated storage disks (DDisks), note the following additional requirements:

•Requires 2 GB RAM per DDisk in addition to the base RAM noted in Table 2.

•Requires an additional 5GB of disk space for application binaries and log files.

•Deduplication is supported only for file systems running on a Linux operating system.

•An Intel Pentium 4 or later processor (or an equivalent AMD processor) is required. For best performance, Quantum recommends an extra CPU per blockpool.

Partitioning Local Hard Disks

StorNext can be installed on any local file system (including the root file system) on the MDC. However, for optimal performance, as well as to aid disaster recovery, follow these recommendations:

•Avoid installing StorNext on the root file system.

•Partition local hard disks so that the MDC has four available local file systems (other than the root file system) located on four separate hard drives.
