SAR

Snap Assisted Replication is built on top of the advanced snapshot mechanism provided
by the StorTrends iTX 2.1 / 2.5 stacks. In a Snap Assisted Replication environment a
primary volume snapshot will be replicated to a volume in a secondary system. Since the
snapshot is a frozen image and the snapshot data is sequentially replicated to the remote
volume, the remote volume will not be consistent until the entire image is replicated.
Once the snapshot is completely replicated, a snapshot will be taken in the remote to
make the volume consistent. Until the replication of a snapshot is complete and a
snapshot is taken on the secondary volume, the secondary volume will not be ready for
mounting purpose. In this fashion, snapshots in the primary system are replicated to the
secondary in the chronological order one after the other. In the remote system, the
recovery points increases snapshot by snapshot and it the maximum it can reach is the
latest snapshot. Each of the snapshots in the secondary is a recovery point candidate for
the volume during a failover.

Schedule

Scheduling allows you set the frequency that the StorTrends® iTX Storage Appliance
takes a snapshot image. The options are Never, Hourly, Daily, and Weekly.

SCSI

cabling connections. SCSI is a parallel transfer protocol that supports 8-bit and 16-bit
data transfers over short distances.

Server

computers. A given application in a computer may function as a client with requests for
services from other programs and also as a server of requests from other programs.

Share
