System Requirements

Memory: 16GB minimum

To show system memory:
- Solaris:
```
prtconf | grep Mem
```
- Linux:
```
grep MemTotal /proc/meminfo
```
Swap space:

Solaris and Linux systems should be equipped with a minimum of 16GB of memory and a minimum of 4GB of swap space. Server configuration and operating system can affect swap space requirements. Generally, no less than 30% of the physical memory is recommended.

To check swap space, enter one of the following operating system commands:
- Solaris:
```
vmstat -S
```
  The result is expressed in kilobytes.
- Linux:
```
vmstat -s | grep total
```
  The result is expressed in kilobytes.
File systems and required databases:

ACSLS 8.5 enables you to install in any file system. You must define the following directories before installing ACSLS.
- A base directory where the ACSLS components will be installed.
- A default directory for ACSLS backups. It is recommended (but not required) to place the ACSLS backup directory in a separate file system from the ACSLS base directory.
Although you can install ACSLS in any directory, the default directories used for ACSLS are:
- /export/home is the default ACSLS base directory.
- /export/backup is the default ACSLS backup directory.
The ACSLS base directory file system requires a minimum of 5GB free. Reserve an additional 5GB free for ACSLS backups. To view file system sizes, enter the following command:
```
df -h
```
The ACSLS creates and uses the /var/tmp/acsls directory for keeping required work files during execution. If you delete or move the contents of this directory while ACSLS is executing, the ACSLS will stop operating and require a restart.
Fibre card is optional. A suitable HBA is required for Fibre Channel operations.
- For target mode operation, supporting the Logical Library feature, this HBA must be a contemporary QLogic fibre card (4Gb or higher).
- For initiator mode operation, supporting a fibre-connected library such as the SL500 or SL150, ACSLS 8.5 is fully tested and certified with QLogic and Emulex HBAs.
