[gpfsug-discuss] Spectrum Scale licensing - Lenovo information

[Michael Hennecke]

Hi,

Thanks a lot Carl for these clarifications. Some additions from the Lenovo side:

Lenovo *GSS* (which is no longer sold, but still fully supported) uses the socked-based Spectrum Scale Standard Edition or Advanced Edition. We provide both a 4.2 based version and a 5.0 based version of the GSS installation packages. Customers get access to the Edition they acquired with their GSS system(s), and they can choose to install the 4.2 or the 5.0 code. 
Lenovo GSS customers are automatically entitled for those GSS downloads. Customers who acquired a GSS system when System x was still part of IBM can also obtain the latest GSS installation packages from Lenovo (v4 and v5), but will need to provide a valid proof of entitlement of their Spectrum Scale licenses before being granted access.

Lenovo *DSS-G* uses capacity-based licensing (per-disk or per-TB), with the Spectrum Scale Data Access Edition or Data Management Edition. For DSS-G we also provide both a 4.2 based installation package and a 5.0 based installation package, and customers can choose which one to install. 
Note that the Lenovo installation tarballs for DSS-G are named for example "dss-g-2.6a-standard-5.0.tgz" (installation package includes the capacity-based DAE) or "dss-g-2.6a-advanced-5.0.tgz" (installation package includes the capacity-based DME), so the Lenovo naming convention for the DSS-G packages is not identical with the naming of the Scale Edition that it includes. 

PS: There is no path to change a GSS system from a socket license to a capacity license. Replacing it with a DSS-G will of course also replace the licenses, as DSS-G comes with capacity-based licenses.

It is not, and I apologize in advance for the length of this explanation. I want to be precise and as transparent as possible while respecting the confidentiality of our OEM partners and the contracts we have with them, and there is a lot of misinformation out there.

The short version is that the same rules apply to DDN, Lenovo, and other OEM systems that apply to IBM ESS. You can update your system in place and keep your existing metric, as long as your vendor can supply you with V5 for that hardware. The update from V4 to V5 is not relevant.


The long version:

We apply the same standard to our OEM's systems as to our own ESS: they can upgrade their existing customers on their existing OEM systems to V5 and stay on Sockets, *provided* that the OEM has entered into an OEM license for Scale V5 and can supply it, and *provided* that the hardware is still supported by the software stack. But new customers and new OEM systems are all licensed by Capacity. This also applies to IBM's own ESS: you can keep upgrading your old (if hardware is supported) gen 1 ESS on Sockets, but if you replace it with a new ESS, that will come with capacity licenses. (Lenovo may want to chime in about their own GSS customers here, who have Socket licenses, and DSS-G customers, who have Capacity licenses). Existing systems that originally shipped with Socket licenses are "grandfathered in". 

And of course, if you move from a Lenovo system to an IBM system, or from an IBM system to a Lenovo system, or any other change of suppliers, that new system will come with capacity licenses, simply because it's a new system. If you're replacing an old system running with V4 with a new one running V5 it might look like you are forced to switch to update, but that's not the case: if you replace an old "grandfathered in" system that you had already updated to V5 on Sockets, your new system would *still* come with Capacity licenses - again, because it's a new system.

Now where much of the confusion occurs is this: What if your supplier does not provide an update to V5 at all, *neither as Capacity nor Socket licenses*? Then you have no choice: to get to V5, you have to move to a new supplier, and consequently you have to move to Capacity licensing. But once again, it's not that moving from V4 to V5 requires a change of metric; it's moving to a new system from a new supplier. 

I hope that helps to make things clearer.
