Each SQL instance gets its own IP (so port 1433 for each) its own drive letter and however many mount points it needs.

I have a mix of instances from 2008R2 to 2016 and haven’t had any conflicts. They work great for HA and other needs (such as Golden Gate replication from Oracle). I currently manage SQL clusters, typically 3 node, that support 15 to 20 SQL instances each and are configured in an A/A/A or A/A/P type of approach. In years past I always liked stand alone or clustered default instances, but in my current role I’ve embraced instance stacking.

Otherwise, you should probably talk to a Microsoft licensing professional to figure out what the Standard Edition licensing requirements will be. In a cluster of hosts, hopefully you’re running Datacenter to keep the licensing headache sane (and to get the additional features for Datacenter that make Hyper-V clustering better, if you’re using Hyper-V).

If you are running any number of Windows Server 2016 Datacenter VMs, once you’ve licensed all the physical cores on the server you’re good to go (again, subject to minimum core licensing). If you’re running 3-4 Windows Server 2016 Standard VMs on a physical machine, you need 2 Standard Edition licenses per core (subject to the same minimums).
Sql server 2017 developer edition install does not run license#
If you’re running 1-2 Windows Server 2016 Standard VMs on a physical machine, you need to license every core on the physical machine (subject to minimums of 8 cores per physical processor and 2 physical processors / 16 cores total). Using Windows Hyper-V on the physical host doesn’t consume any licensing above what’s required for the guests, so the licensing rules are basically agnostic to whether you’re using Hyper-V or VMWare. – Datacenter Edition includes an unlimited number of OSEs or Hyper-V containers, once the physical cores in the server have been licensed per the above guidelines. a 4-socket server with 4 cores per socket would require 32 core licenses, not just the server minimum of 16). – A minimum of 8 core licenses is required for each physical processor (e.g. – A minimum of 16 core licenses is required for each server (regardless of the actual number of cores) For every two additional VMs, all cores in the server must be licensed again. – Standard Edition provides rights for up to two OSEs (operating system environments – in other words, VM guests) or Hyper-V containers when all physical cores in the server are licensed. Though for VMWare or Hyper-V hosts, a similar functionality exists with the Datacenter Edition licensing (taken from the Windows Server 2016 licensing datasheet – ) Plus, surprise bonus: every VM, even the tiniest ones, get all of the features of Enterprise Edition.

Then, each VM gets their own performance management, patch schedules, and security. Yes, this does mean higher licensing costs – you’ll need to license SQL Server Enterprise Edition at the hardware host level, and then you can pack in as many VMs as possible into the host. It’s a great default place for new SQL Servers.Įvery SQL Server deserves its own Windows instance. Whenever you think about carving up a single server into smaller pieces, think virtualization instead. If they insist on being sysadmin on the box altogether, then they can make changes that wreak havoc on the other running instances. Security challenges – sometimes, we get those awful folks who insist on being able to RDP into the Windows instance that hosts their databases. Much harder reboot planning – you have to get all of the customers on all of the instances to agree on a time to patch Windows.

If none of the instances are performance-sensitive, this doesn’t matter – but how often does that happen? And how do you figure out what the “right” memory or CPU settings are? It takes so much human work and experimentation that it really only makes sense when you have plenty of free time per DBA per server. A backup on one instance will knock out performance on the other instances regardless of how much tuning work you put in.

While SQL Server does offer tricks like affinity masking and memory settings to alleviate the first two, it’s got no answers for the second two. Much harder performance tuning – all of the instances share the same CPU, memory, network pipe, and storage pipe. Lower Windows licensing costs – you only have to pay for one Windows.Įasier Windows patching – since you only have to patch one OS install. Lower SQL licensing costs – you only have to pay for one license, and then even Standard Edition lets you install dozens of instances on the same Windows base.
