Bulk Storage Clusters
Network is configured with one of the virtual cluster server
techniques.
The disk storage is connected with Fibre Channel including SAN
file systems.
SAN(Storage Area Network)
- Scalability ->125 disks w/ one controller
- Easiness of Management
- Fast Disk I/O Speed -> 100 Mbytes/sec ( half-duplex
), 200Mbytes/sec (full-duplex)
- Long Distance -> over 10 km (fiber-optical cable)
Linux Supporting File Systems
- ext2/ext3 file systems
- ISO 9660 (CD-FS)
- VFAT / FAT
- SMB (CIFS)
- UFS
- NTFS
- UDF ( DVD-FS )
- NFS / CODA
- LVM ( Logical Volume Manager )
- GFS ( Global File Systems ) - allows multiple
Linux machine to share storage devices over a network. Each
machine sees the network disks as local, and GFS itself appears
as a local file system. Writes to a file by one Linux machine
are seen by another machine that later reads that file.
- Reiser FS ( Journaling File Systems ),
SGI XFS, IBM JFS
- RIO ( Raw IO )
- RAMFS
- ROMFS
