FileStore – NetBackup Integration Advantages
• FileStore ships with an embedded NetBackup SAN Client, which
allows customers to run backup jobs directly over a SAN.
• The SAN Client has significant advantages over NDMP:
– Faster backups: SAN client backups run 5-10x faster than NDMP.
• SAN Client @ 400MBps-500MBps / NDMP @ 30MBps-70MBps
– Easier configuration/admin: With SAN client pre-installed, a user need not
walk through an NDMP configuration and authentication process.
– File-level recovery: NetBackup allows fast, simple recovery of files.

FileStore – Symantec AV Integration Advantages
• FileStore ships with an embedded Symantec AV client, which
enables users to run AV directly on the FileStore cluster. Users
can dispense with external AV servers.
• Advantages of embedded AV:
– Faster file access
• Reduce network overhead by 20%
– Easier administration: Control AV from the FileStore GUI
Reduce costs with native

FileStore – Symantec Storage Tiering Advantages
• FileStore users can activate storage tiering, which automatically
moves data between disk tiers based on usage patterns.
• Advantages of storage tiering:
– Reduce storage spending by storing less used files on low-cost disk.
– Flexible policies – demote by inactive days; promote by “heat”score

Disk Pools are shared across the
FileStore cluster.
Snapshots available using Veritas
checkpoints. (copy on write).
Filesystems can be dynamically resized
(grow / shrink).

19
FileStore Storage Tiering
• Single name space:
– one filesystem.
– dual storage tiers.
• Administrator defines policy on when to relocate files based on access time.
– 30 / 60 / 90 / #x day policy options for atime.
– Place files in secondary tiers and promote to primary based on I/O throughput.
– Manually move files/folders as needed.
• Files go where they should when they should automatically and transparently.

Directories are not supported as shares (1 share per fs)
Multiple file systems can be used for home directories
For regular (non home-directory) shares
– User visible share is a proxy share w/ single
target DFS referral
– Load balancing is done by moving a VIP w/ its
shares to another node
For home-directory shares
– Exposed as DFS links (single target DFS
referrals)
– The target share is the homedir file system &
exists on one node
– Load balancing is done by moving VIP w/
homedir (all homedir shares)

FileStore Replication Overview
• FileStore Cluster replication:
– Asynchronous file-based replication.
– Complete file or block delta transfers.
– Multiple filesystems supported with directional reversal.
– Uses known rsync for transport between nodes.
• Prevents need for separate network configurations to support proprietary protocol.
– Uses Veritas technology to know which files changed without walking
filesystem. (Veritas FCL).
– Destination can be on-line for reads. Updates are applied to non-live FS
image (checkpoint) and then ‘flipped’ to live FS.
• FileStore Replication pricing and licensing still to be finalized.

Replication is performed on
a per filesystem basis.

uses snapshots and
the Veritas FCL to
monitor changes made
to the filesystem
Changes are then applied to a snapshot
and then ‘flipped’ into the live filesystem
once update is complete.
