EMC to IBM SAN LUN replication
Hello all,
I have been asked to look into possible solutions to replicate luns between an IBM and EMC SAN. Our production data is on an existing IBM SAN and we have just 'aquired' an EMC. Does anyone know of a product from either company or third party to replicate LUNS accross the two?? thanks.... |

EMC to IBM SAN LUN replication
what do you mean replicate LUNs across? for DR, or ?
Also, what's the model of IBM storage you have and also model of EMC storage you have? Firmware versions as well would be good mackdaddy315 wrote: Hello all, I have been asked to look into possible solutions to replicate luns between an IBM and EMC SAN.

Most SAN vendors like others migrating onto them. Even though there are standards for SAN, a lot of closed things exist. cross platform replication is among that. EMC provides SANCopy tool for one time migration from other arrays onto EMC arrays. Hitachi may also provide something similar..but real time synchrounous replication is yet to arrive if I am correct. You may try a host level software, I believe EMC recently aquired one similar company. Or simply utilise a host lelel DR solution to replicate data across. e.g. I would assign same size of storage to the host from both arrays. And then mirror the devices using volume manager to maintain real time redundancy. Kiran Ghag |

Theoretically, IBM SVC should be a proper solution. On the other hand, it might be too expensive, especially if you have only two storage enclosures. Also, SVC is not working with some entry level enclosures, like EMC AX 100. It would be nice if you can give some other details, like type of enclosures, SAN topology (with distances) etc. With best regards, Iggy |

EMC to IBM SAN LUN replication
EMC has a product that will replicate from any san to any san. It is
called kasha and is vender nuetral. It will work on any environment and is host OS agnostic. That is the best solution on the market to do what you are looking for.

Falconstor might be an option for you Rob |

EMC to IBM SAN LUN replication
There are nurmous cluster filesystems that will work for your solution.
IE: Windows http://www.polyserve.com/matrix_server_windows.php http://www.veritas.com The real question is why do you need this? Is it for a high end application or simple file sharing? If it is simple file sharing you may want to use another solution. You would be making this overly complicated for no reason. Check out freenas.org they offer a linux OS specifc to nas that you can use. It will install on the existing hardware that you are using and provide CIFS access to the windows machines.

EMC to IBM SAN LUN replication
All,
Sorry i was away for a while and have not been able to post back. Basically what I am looking to do is create a hot spare site. I have a set of Windows Clusters (file servers, exchange servers, and SQL servers) currently connected to the IBM SAN. I am looking for the ability to mirror those LUNS to the other SAN and have another node of each cluster connected at the other site in case a complete site failover is needed. From what I know about the IBM LUN mirrorining option it would do this with another IBM SAN but when you wanted to fail back you would have to break the mirror set and recreate the mirror. |
