As we know, replication solution of HUS110 is TrueCopy.
For HA, what is the solution of HUS110?
May I say HUS110 is "HA" architecture already due to there are dual controllers inside.
charles liu, What are you trying to achieve? Please explain briefly so that we may be able to help you correctly.
HUS is a Symmetric Active-Active architecture, Load will be automatically balanced between the controller. There is no single point of failure, If one of the controller fails, the second controller will take over the functions handled by the failed one but with degraded performance.
Are you trying to setup TrueCopy Sync between 2 HUS?
We’re not trying to setup TrueCopy.
Thanks for the information about HUS110 HA architecture.
I’ve a question about TrueCopy.
I saw two kinds of TrueCopy
For TrueCopy Extended Asynchronous Replication, there is a description about the technology in the document.
“Cycle time is the interval between updates from the P-VOL to the S-VOL.
Cycle time is set to the default of 300 seconds during pair creation.”
I presume the minimum replication interval is 300 seconds (i.e. 5 minutes), is it right?
But for “TrueCopy Remote Synchronous Replication”, I did not find similar description.
Does it mean TrueCopy Remote Synchronous Replication is “continuously” replication? No interval can be configured, is it right?
May I say it a kind of “HA” with TrueCopy Remote Synchronous Replication?
TC Sync is continuous replication. The host must receive ACK from remote array to complete I/O transaction.
