StarWind Software

All,
The documentation is a little light on differences between HA and RAID-1 devices.

From what I can gather, the main benefit of the HA device is that both targets can be active concurrently. Also, the ability to sync to a 3rd host is a benefit.

With RAID-1, is the backup target accessible while it is receiving replicated data from the primary? I would imagine not.

Any info other than what's in the documentation would be appreciated.

Thanks,
Elvis

HA is fault tolerant (with one node going down second one keeps handling I/O so client notices nothing) and RAID1 is not (primary node goes down - downtime).
So RAID1 is a one-way synchronous replication and HA is two-way. Making long story short: we'll be replacing RAID1 with async replication in upcoming V8 making RAID1
mode within StarWind obsolete.

Thanks for the quick response. I won't waste my time with Mirror then in configuration planning.

On to v8!

That's a good idea!
