If you would like to estimate memory size required for your data, please refer to Estimate Memory Requirements for Memory-Optimized Tables. The limits for In-Memory OLTP data is per database. On all lower editions of SQL Server 2016 starting with SP1, we have memory quota limits for In-Memory OLTP data and Columnstore segment cache which is in addition to the maximum buffer pool memory limits described earlier. This is not specific to SQL Server 2016 SP1 and is also applicable to earlier releases of SQL Server as well.Įssentially, SQL Server in lower editions can consume and utilize memory outside the maximum buffer pool memory limit defined in the table above due to memory consumed by other caches. The memory consumed by caches outside buffer pool is not restricted by above memory limits and can grow up to limits defined by 'max server memory'.

The rest of the caches in the SQL Server memory (procedure cache, thread stack, backup buffers etc) consumes memory outside buffer pool memory. In simpler terms, buffer pool memory in SQL Server is a memory cache responsible for caching data and index pages for the entire instance. The memory limit defined for lower editions of SQL Server is essentially Maximum buffer pool memory limit. In the past, the memory limits defined in table above in the SQL Server editions page for lower editions were referred to as Maximum memory utilized per instance which did not accurately reflect the true limits. Understanding the Memory limits for lower editions of SQL Server Doesn't really excuse MS, even their licensing 'experts' never bothered to point this out in the course of the past nine years, but at least it explains why not many people seem to 'know' about this.Memory: Maximum memory utilized per instance buffer pool size per instance 20+ cores means you have a seriously loaded database, a budget that doesn't even flinch at buying a server that costs 6 figures, and multiple levels of bosses that are all on the same page. Even then, if scale- out strategy is usually 'the norm,' you'll normally have not-quite-beast-level servers. in fairness to the community at large, most DBAs don't ever see a server with more than 20 cores unless they're in a large enterprise environment. This is also assuming you didn't monkey with processor affinity. '40' and 'twice' are assuming HT is enabled if not, half those figures. With the Core edition, you'll see twice as many rows as you have cores. Cores in-use show 'VISIBLE ONLINE.' If you have more than 20 cores, but the non-core edition, you'll see only 40 rows with that status. Check sys.dm_os_schedulers, in particular the 'status' column. You can verify this yourself, the same way I finally discovered it, on a server with more than 20 cores of course.

I'm lucky though - I have a cool boss, plus three teammates and two lead developers that also had no clue about this, backing me up. yeah, we were effectively wasting 40 core licenses. I ran into this the hard way, on a server with 60 cores, running for over a year, and because admittedly I was not paying enough attention. Or be sure you have an unloved teammate you can throw under the bus. documentation about the 'Core-licensing' edition is extremely lacking. Yes, that sucks - so if your boss is itching for a reason to fire you, be sure to point out that yeah. Yes - that means you're wasting a LOT of money. Even if you're paying for core licensing, and paying for more than 20 cores on a server, it's still capped at 20. The non-core edition, as others stated, is intended for Server/CAL licensing.

If your host has 40 cores but you never assign 20+ to any guest, don't worry about it. I'm not sure how or why anyone would give a VM more than 20 cores (at that point your host is already a dedicated server most likely), but if so.

Just how many are assigned to the Windows VM.

Virtualization side-note: this has nothing to do with cores on the host.

As in it takes longer just to get to the Upgrade button in setup, than to actually perform the upgrade when you hit it. The good news: an edition upgrade from non-core to core is utterly painless and very fast. I ran into the specific question 'when do I NEED the Core edition, vs. This is not a guess, it's a provable certainty. Short: The regular 'Enterprise' (non-'core') edition caps the cores at 20, period.

Sorry to necro here, but just in case someone else hits this page with a similar question, and since there's so little documentation about this.
