Sybase MPP Release 11.0<br />
4.1.4. Disk Space Requirements<br />
<strong>The</strong> amount of disk space required on each node depends on how<br />
many realms (base realm and regular realms) you install. Sybase<br />
MPP software requires 250MB of disk space regardless of the number<br />
of realms, but the amount of space required for log files and database<br />
backups depends on the number of realms.<br />
Space for Sybase MPP Software<br />
Make sure that you have 250MB of disk space available on each node<br />
where Sybase MPP is to be installed. This includes approximately<br />
100MB for the SQLSERVER directory and 100MB for the<br />
MPPSERVER directory.<br />
Space for Log Files and Database Dumps<br />
Sybase MPP creates and maintains supplemental log files for all<br />
running servers except SQL Servers. By default, each log file can<br />
grow to approximately 20MB, although the file size is configurable.<br />
<strong>The</strong> Backup and Restore utility requires 16MB per realm for dumpdb.<br />
In addition, each SQL Server creates a small error log, but the disk<br />
space required for it is negligible.<br />
Total Space Required Per Node<br />
• Log file space = (number of primary servers on all realms +<br />
number of alternate servers on all realms) x 20MB<br />
• dumpdb space = number of realms x 16MB<br />
• Total per node space = 250MB (Sybase MPP software) + log file<br />
space + dumpdb space.<br />
