Migrating from HSG to EVA

[Denzo Waruna]

I've been running HSG80 for the past 2 years and I am now in the process of planning for the next 3 years. What I want to know is whether I need to migrate to EVA and if so what is the justification. I also need to know the costs involved.

Denzo,
the HSG is a product that has reached the end of it's life - my first training on it was in October 1998, so that is quite some time...

The EVA technology is much more powerful and flexible than the HSG, but what really counts are your requirements and you have not specified them.

For costs(money) I suggest you contact a local supplier or did you ask for migration effords?

Denzo,

As Uwe mentioned, HSG80 is an old technology and will shortly become end of life.

EVA (HSV110) is relatively expensive to the HSG80. However, it has lots of improvements in handling and propogating fiber communication failures, which was a major issue atleast in the initial days of fiber-channel technology. HP treats EVA to be an enterprise product and hence they give you support directly and does not allow any dealer to sell you their support. Further more, the system is built redundant in every component with no SPOFs (and that makes it more robust and more expensive). If you are using Tru64 Unix and AdvFS, then migrating to EVA is not an issue, as you just use the AdvFS (addvol,rmvol) commands to migrate to the new storage online. As Uwe mentioned, start talking to a HP Technical Sales guy.

Cheers

The EVA-3000 (using HSV100 controllers) seem a better fit unless you need more than 56 disks.
