One problem with this solution is that synchronous replication requires lots of duplicated space. I wish Dell would address that issue. It really wastes a lot of space and it does so in a way that the amendment space required is inefficient. Once it is running it does not need as much space, but to start it up you need double the space on both your source and destination chassis. Another issue is that I can not mix RAID technologies. On one particular box, I can only set one RAID standard and not create multiple RAID sets. That is a limitation that I could do without. One feature that would have been nice on the EqualLogic box is the ability to recover on a file basis. It should not be limited to a volume scale. I do not know that it should be able to recover files being that it is a block-level device for storage. File-level is a completely different animal. But it would be nice to be able to have file recovery even if it is a block-level storage device.
