Hi,
We are migrating from Storwize V5000 to FlashSystem 5030 and want it to be non-disruptive so going to use LCM disk mirroring.
· Prod at site A
· DR & test at site B
· Cross site SAN & Network
· Currently Prod data has FlashCopy to target volumes on Test system at opposite site (So same model at both sites)
We will migrate Test first, then DR and then test to FlashSystem 5030's sitting in same rack as their Storwize counterpart.
My questions are:
· When we migrate the data from V5000 to new FS5030 can we change the V5000 FlashCopy target from a V5000 to the FS5030 so we don't have to cut-over all systems at same time. I plan to add it to our pre-migration testing, but wanted to know if any gotchas or if it won't work even.
· Also we need to demonstrate the FS5030 will provide the same or greater performance, are there any free tools that will help, we are using AIX LPARS, we thought a simple DD copy with small and then large block size.
Any thoughts welcome
