Anti-virus protection
l
Storage Mirroring Recover queues—Exclude the Storage Mirroring Recover
queue directory on the source and target from any real-time scanning or scheduled
system scans. If a queue file is deleted by a process other than Storage Mirroring
Recover, unexpected results may occur, including an auto-disconnect due to the
loss of queued data. The files in the source queue directory have already been
scanned (cleaned, deleted, or quarantined) in their original storage location. The
files in the target queue have already been scanned (cleaned, deleted, or
quarantined) on the source.
l
Target data—Exclude the copy of the source data stored on the target from any
real-time scanning or scheduled system scans. The files have already been
scanned (cleaned, deleted, or quarantined) on the source. If the replicated data on
the target must be scanned for viruses, configure the virus protection software on
both the source and target to delete or quarantine infected files to a different
directory that is not in the replication set. If the virus software denies access to the
file because it is infected, Storage Mirroring Recover will continually attempt to
commit operations to that file until it is successful, and will not commit any other
data until it can write to that file. Additionally, if the virus protection software cleans
the file, an operation to clean the file will likely also be replicated from the source,
which may result in file corruption.
Hardware configurations
l
NIC teaming—If you are using NIC teaming, set it up for fault tolerance, not load
balancing.
l
Device drivers—Keep your hardware device drivers, especially NIC drivers, up-
to-date.
l
Port speed and duplex—Set static values for port speed and duplex on NICs and
switches, if possible.
