RE: DR realtime replication

Laurence Chiu,

I would be happy to have a conversation with you regarding external storage options for IBM i. Strengths/weaknesses and the value it can bring in an HA environment. Steve pitcher and I are also doing a webinar next week where we review internal vs external storage. Send me an email and we can set something up.

Have a great day.

Well I had a good chat an IBM SME on their Spectrum Virtualize SAN products and software. Seems like it will do what we want. The question is, does the business think it's worthwhile or are they happy with software based replication using Mimix, and manual recovery processes should there be a DR event and need to flip over to the DR site. Also are they happy with the data not being encrypted at rest. And not to mention no protections against ransomware infiltrations.

Not in the US but it's not relevant now given global travel restrictions.

I did have a session with a storage SME with IBM and it seems like the
Spectrum V5030 product might meet our needs.

It has Metro Mirror and encryption so nothing needs to be installed on
the Power server. And using this basic configurator I came up with
numbers that were not too bad

You really probably should go to something like the following:
https://powerup2020.sched.com/overview/type/High+Availability+Resili
ence I picked a link targeted to your questions.
However if you're under a travel ban I can see that being an issue.
There are some sessions in there like:
Evaluating IBM H/A options

If you can't make it to COMMON go down the list of sessions at the
link I provided and see if someone there would like to talk to you off line.
You
might be able to find them on LinkedIn, etc.

I've been looking at this scenario also with two Power servers about
40km apart doing real-time replication (mirroring), My background is
IBM mainframe and we do this using IBM DS8K SANS and Copy Services
Manager running on the SANs. Ironically the DS8K SANs run two Power
8 servers
each!

Anyway digging around came across this IBM SAN product

https://www.ibm.com/products/flashsystem-5000/details

The software supports remote mirroring according to this Red Book

https://www.redbooks.ibm.com/redbooks/pdfs/sg248162.pdf

While the Power 8 systems we have don't have lots of data, it's
mission critical and need to be protected

I find it easy to use and faster the other software. We do "Role

when we need to do upgrades & have very few problems.

changes to DB's is all we are looking for at this time. I can sync
programs
and other objects manually as they are changes/deployed to production.

You use the term "realtime" in your subject line, but I wonder
if you're referring to database events (add, change, delete) or
any updates to IFS directories and stream files as triggering
events for replication? Or would a daily snapshot suffice?

Replication is only needed 1 way (prod to DR).

Any suggestions on either packages or in-house solutions?
