Anybody Sierra running virtually (VMware, HyperV, etc.)?

We have a very solid virtual environment (blade server chassis, fibre channel SAN) and looking into the possibility of running Sierra virtually, instead of on a dedicated physical server.

The virtual environment exceeds the physical server specs.

If you have any experience, or 'experiences', running Sierra virtually please let us know.

Have a great day.

It seems like their spec is overly generous.
So far every time I've gone from physical to virtual things perform much faster.
And makes Disaster Recovery, backups, and most other things easier too.
I suppose direct experience is the best gauge.

So far what I'm seeing is that many people are running Sierra virtually with great success but there hasn't been a lot of information posted yet about it.

Hi Bill,

We'd be super-interested in people's experiences with hosting VMs. We currently have Millennium on a VM and SSO on another (VMware/VSphere environment on HP blades ), but with pretty small footprints.

We are upgrading to Sierra/Encore/SSO (plus test envs for all..so 8 VMs in total, all running RH Enterprise 7) this summer, and our Technical Architect has stated that the recommended spec from Innovative (attached) is far too over-specced to the point that it might actually slow things down! We have built them to the spec, but hope to tune these in the long-term to match the performance required.

Thanks,
Andrew

We followed iii's guidelines regarding # cores, etc. (which I've provided you in our hardware specs). However, we are running Sierra App and database AND Encore all on one physical server... I hope that helps!

Hello! We here at London Public Library (Ontario, Canada) are running Sierra App, Database and Encore all on one physical server as 3 separate virtual machines in a VM environment (and sometimes as many as a dozen other virtual machines (websites, print servers, email servers, etc. on the same physical server). For day to day use, it is also running on a SAN. We don't oversubscribe -- e.g. we allocate dedicated processors and memory to each virtual machine. Our hardware is:

1 HP ProLiant DL580 G7 Server

2 U2Z68E HP 3 Years 24X7 Procare service

We also purchased and installed RedHat Enterprise Linux 5.0 , 64 bit at the time. We have since upgraded to CentOS 6.

We purchased and installed VSphere Enterprise licenses (VM ESXI 5.1) -- we're now on ESXI 6.0.

Though we do VM copies of the vm servers, we also purchased the Enterprise Backup API from iii and we backup onto a drive which we store off-site. We have a DR site.

With all of this, we are running less than 10% usage of the server resources! We have excellent Sierra and Encore performance!

I hope this helps you! Let me know if you have any further questions!

Thank you Eeva, this is great news. We may want to follow up with you for more info but will look into these specs.

Hi,

We have three III servers (sierra app, sierra db, and single sign-on) which are each on a separate vm within our campus's data centers. I'm more of a systems library than a system admin, so I can't say much about the virtualization piece other than we run on vmware. However, we switched to vm's from physical servers back in 2014. As far as I can remember, we've never had any problems with running on virtual servers, and it didn't change our support experience either. (We are a software-only site, not sure if that's relevant or not.)

Hope this helps. Take care,
Joe Montibello
