Re: Compatibility between different vendors VTL solutions

The connection over Ethernet is curious at best.

What sort of device then does it appear to be? Is it FCOE so it's really fiber in the end?

Honestly I would be terrified of that setup until I saw a solid recovery plan on how to recover with an Ethernet connected backup device!!

The tape drive is not connected to either to the production or DR server
but to a third server in yet another DC albeit network connected.

The ProtecTier VTL is not fiber channel connected to the Power servers but
over Ethernet.

If you have to use physical tapes do not think save/restore. Think

And "have to" is totally subjective.

I'd imagine if there's a ProtecTier VTL there should be fiber channel. I'll
have to ask.

The old server does have a LTO6 drive and we intend to put one LTO6 drive
in the new data center connected to one Power server. So I was thinking as
a slow manual process we could dump out a number of backups to one tape fly
that to the other data center and restore it. Each backup would be a about
a terabyte so you could write quite a few to one tape.

The plan in the new data center is to use VTL but a tape is just there for
contingency.

In the old DC you would need a FC connection from your Power system to
your switch then to your new VTL in that same old DC.

Alternatively could we dump a number of backups to a lto6 tape cartridge,

You mean you could do DUPMEDBRM to LTO6 at the old DC. Ship them over to
the new DC. Do a DUPMEDBRM from LTO6 to the new VTL.
Right?
Why would the new DC even have a physical tape library?
We have no physical tape drives or libraries. None. Haven't for years.
Never been an issue. Done bare metal restores. Don't even send physical
media to IBM anymore for in depth problem solving. All MSD's, etc go via
internet.
With the money you'd spend on physical media, libraries, shipping and
manual labor are you sure you wouldn't be better off with another VTL?

No budget for a third but could possibly stretch to putting one in the
primary DC, connecting it to the ProtecTier VTL and dumping to the new
VTL
using DUPMEDBRM.

Then ship the VTL to the remote site.

What sort of connection would the second VTL require to the Power server?

Alternatively could we dump a number of backups to a lto6 tape cartridge,
ship that over and restore that to the new VTL?

Do you have enough pad in your budget to put a third new VTL at the old

old
DC
could then replicate to the other new VTL's. In the old DC you would
need
a FC connection from your Power system to your switch then to your new
VTL
in that same old DC.

From an lpar on my Power system in Indiana I can run a
WRKMEDBRM TYPE(*ACT) SYSNAME(lpar in Michigan)
Then with a little mumbo jumbo done on the VTL I can restore a save
done
in Michigan on to a system in Indiana. This is how we do our saves on
our
H/A production backup lpar in Michigan to our primary development lpar
in
Indiana. This is how we refresh our test data.

The existing DCs have ProtecTier VTLs. The other remote DCs have no
Power
servers nor VTLs but we are planning to put one in each location each
with
its own VTL.

I'll have to prefix all my comments that I'm not a IBMi person. My
background is z/OS but got involved because of my technical
background.

As for backing up VTLs the plan is to have 2, one in each DC with
replication between them both. That is how we do mainframe backups.

How do you plan on backing up your new VTL at your local DC? Or
