2.1.5 Required memory

The following table shows the memory required when this software is operated in the following environment:

No.	Memory (in MB)	Operation
1	316.5	A cluster system is operated under the following conditions: One cluster application is registered in a cluster system. Note that 96.8 MB is required for each additional cluster application. Web-Based Admin View is operated in two-tier model. GDS shared class operation. GLS takeover IP address service registration. In addition to the aforementioned user memory, 2.0 MB of kernel memory will be allocated per CPU by vmalloc.
2	38.0	After a GFS shared file system is set up.
3	145.0	When one GFS shared file system is activated. If multiple file systems are activated, 145.0 MB is required for each file system. 2.0 MB out of 145.0 MB is allocated in virtual address space by vmalloc. Overestimate the amount of memory because memory usage may vary according to the file system load and cache tuning.
