SAN Copy pull or push

Question

Hi All, We've a CX3-10 and a CX4-240 with around 100kms apart from each other. . We plan to make CX3-10 to store copies of CX4-240, thus intend to purchase SAN Copy. My doubts are as follows:- - If we purchase SAN Copy for CX3-10, would be able to pull data from CX4-240 and also how about Incremental SAN Copy how would it work? - If we purchase SAN Copy for CX4-240, i suppose we would be able to push to CX3-10 and also pull from CX3-10? Appreciate your inputs for us to make the right decision of SAN Copy license and on which array to install it. thanks and regards, Samir

buy SanCopy for CX4 so you can perform incremental push, can't do incremental pull with SanCopy.

To add to Dynamox’s reply..

SANCopy Full can push out from a CX/VNX, or pull in to a CX/VNX with just a local SANCopy license. The second array does not need to be an EMC array.

SANCopy Incremental only supports Push, only between two CX/VNX systems, and must be licensed on both arrays.

Hi Guys, Could you please let me know or guide us on how much bandwidth would be required? regards, Samir

So if we buy SAN copy on CX3-10, we should be able to pull data from CX4 system?

dynamox · Answer

sure, you can pull from CX4 but it's alway a full copy, why not incremental push from CX4 ?&#xa0; As far as throughput is concern ..i am sure you have not heard this before ..'It Depends' .&#xa0; It depends on how busy source/target arrays are, latency on your link, pace that you set for sancopy sessions.

I asked that question many times: no, he doesn’t have a life, needs no sleep and uses the forum as a lifeline ☺ I fear that without the forum, Dynamox will fade away….
