Re: ScaleIO license removal

Hello triggs88,

when I wrote my previous message today there was a limit in my method, it required ScaleIO infrastructure shutdown to change license.

I made some improvement working with shm descriptors and now I'm able to transform the license without downtime.

Now I'm writing a script to automate this task. If someone at EMC is interested could contact me, I'm happy to share my work with them.

I prefer to distribute such kind of tools only with EMC approval. Maybe it's better to share informations with EMC directly so they can double check my work and they can share my work to the community.

@osaddict: contact me if you consider appropriate so I can share with you some informations.

Thanks,

Davide

Re: ScaleIO license removal

Hi guys,

I created an automated python script for this task. The MDMs must be linux, I tried it on my ScaleIO infrastructure installed on Ubuntu and it works perfectly. I don't know if the SIO installation path and SHM descriptors are located in the same paths on every distribution but I can explain the actual limits so someone can improve it adding some additional check.

@osaddict: if you are interested I can share the little script with you so EMC team can make a check, fix and improve it.

Regards,

Davide

Re: ScaleIO license removal

Hi Pawel,

I'm very happy to send you my little dirty script. There are some comments in code.

I tested the script on Ubuntu 14.04 with ScaleIO version 2.0.0.2 and on Ubuntu 16.04 and ScaleIO version 2.0.1.0. It is a fast hack so it requires some revision but in my scenario works perfectly.

It must be executed only on the (currently) active MDM node. ScaleIO replicates the changes on the othen MDM cluster nodes.

Let me know what you think.

I'm very glad to help.

Regards,

Davide

Re: ScaleIO license removal

Hi Pawel,

feel free to redistribute the script after an accurate revision and also to improve it in order to make it safer and (eventually) compatible with different linux flavors.

Davide

Re: ScaleIO license removal

Hello,

If you read the EULA, the product is free to use only for evaluation and demonstation purposes. If you look at the text you agree to when downlading, you will see the section below. This mean that even for development and test environments, a license is required.

"

E. “Internal Business Purposes” means an internal (non-commercial) Use for the purpose(s) of testing and demonstrating the features of the Software, and not for Customer product development, product testing, or other Customer research and development or commercial purposes.

Re: ScaleIO license removal

Hello osaddict,

as explained yesterday to Pawel I'm working with a commecial licensed version of ScaleIO (TIER1).

I understood why triggs88 is asking this feature. Think about this scenario: I'd like to try to import some data for a new project because I have to demonstrate to a customer that my cloud infrastructure is suitable to host his services on my cloud infrastructure and I need temporarly some extra space to let him check the services (before contract stipulation). I know that the ScaleIO storage is in production for the storage space already licensed but I have also some space used for evaluation (temporarly). If the hypothetical customer is satisfied he will sign the contract then I can license the extra ScaleIO space.

I don't have problems to license more space with a signed contract but often I have to demonstrate that the VMs of a customer work well on our infrastructure in advance.

Switching back to trial can be useful in that scenario.

For example when I contacted ScaleIO presales I asked if the size limit was really locked. Our company for example sometimes need to extend capacity on request (immediately) and it takes a bit to license the extra space because we have to:

- contact the EMC sales team

- wait for an offer

- confirm it

- wait for license release

Our company is small so buy a bigger license in advance can be a problem. The EMC presales team (when we bought ScaleIO) replied me that the the limit is only administrative (written on paper) and that I could go temporarly over the limit (because the size is not really locked) and then acquire contact them to license the additional space. They said that the only drawback is that support is suspended until our full “RAW storage space” is officially licensed. We are in production from 19 days with ScaleIO and I understood that this is a wrong statement when I read the post of triggs88. I have all the emails of presales support stating what I’m saying.

A little bit of flexibility from this point of view can help little companies that can't license in advance bigger amount of storage space without really overcome the license.

That's why I think that the request of triggs88 make sense.

Kind regards,

Davide

Re: ScaleIO license removal

Hello osaddict,

I know that is a completely different type of product because is based on monthly basis payments but for example Microsoft SPLA permits customer evaluation:

- it permits to fully license a product for up to 60 days to provide software services to prospective customers.

spla_60-days.JPG.jpg

That is extracted from the SPLA datasheet.

In the past I realized a virtual infrastructure to permit a customer to evaluate it. At the first SPLA report I had already the contract signed so I reported that licenses immediately because the contract in this scenario mark the switching in production.

I could understand that talking about storage is different but, I think, that the evaluation period from the point of view of the final customer is important. ScaleIO is used also from cloud infrastructure provider that deliver services to final customers.

That is only my opinion, obviously EMC can decide how it's software can be used and all the customer have to respect these decisions. Maybe EMC can evaluate if the depicted scenarios could be covered by the contract (in some way).

Kind Regards,

Davide

Re: ScaleIO license removal

Hi osaddict,

Davide, hit the nail on the head really.  Sometimes we struggle to show the customers what ScaleIO can really do if we don't have the flexibility of evaluation license.

If we really did upgrade the license to allow more storage and then the customer decides to not purchase the product then we lost the money, so you can see the chicken and egg situation that alot of providers/resellers are struggling with.

Thanks,

John
