| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. A clustered file
system is a file system which is simultaneously mounted on multiple
servers. There are several approaches to clustering, most of which do
not employ a clustered file system. While many computer clusters don't
use clustered file systems, unless servers are underpinned by a
clustered file system the complexity of the underlying storage
environment increases as servers are added. A shared disk file system
uses a storage area network (SAN) or RAID array to provide direct disk
access from multiple computers at the block level. Translation from
file-level operations that applications use to block-level operations
used by the SAN must take place on the client node. The most common type
of clustered file system, a shared disk file system adds a mechanism for
concurrency control which conventional filesystems intended for local
storage do not have. Clients are afforded a consistent and serializable
view of the file system, avoiding corruption and unintended data loss
even when multiple clients try to access the same files at the same
time. |
