This article applies to Parallels RAS version 16 and up to Parallels RAS version 19.
Parallels RAS uses concurrent-user licensing. This means that a given user can establish any number of connections to Parallels RAS as long as the number of users simultaneously accessing Parallels RAS does not exceed the number of available licenses.
Consider the following examples:
- One user, one device, one connection — one license is needed.
- One user, one or multiple devices, multiple connections — one license is needed.
- Multiple users, each establishing one or multiple connections — a license is needed for each user. When all licenses are used up, the next user will have to wait for one of the current users to log out from all sessions.
The following table shows license consumption by connection type and user rights:
| Connection Type | User Rights | Consumes RAS License |
|---|---|---|
| RAS desktop/published application connection | Non-admin | Yes |
| RDP desktop/published application connection | Non-admin | Yes |
| RAS published application connection | Administrator | Yes |
| RAS published desktop connection* | Administrator | No |
| Direct or tunneled RDP desktop connection* | Administrator | No |
*Maximum up to two connections of either type per RDSH server.
Prepaid Subscription
You license Parallels RAS with a prepaid subscription, which works as follows:
-
Your active subscription allows you to upgrade to a newer version of Parallels Remote Application Sever whenever one becomes available.
-
A subscription is purchased for a predefined period of time, either one month, one year, two years, or three years. One-month subscriptions can only be purchased online.
-
If a subscription is purchased online, by default it is set to automatically renew when the subscription period ends. Subscriptions purchased through a reseller must be renewed through the reseller.
- Support is included in the cost of the subscription. You can choose either the Standard or Premium support plan.
Grace Period and License Overuse
Grace Period
To ensure uninterrupted Parallels RAS operation, you should renew your subscription before it expires. However, if your subscription does expire, you will be able to continue to run Parallels RAS for a period of 30 days, which should give you enough time to renew your subscription.
License Overuse
Parallels RAS gives you a grace period of 7 days during which time you can connect more users to a farm than your subscription terms specify.
To continue providing access to the increased number of concurrent users, you should purchase more licenses before the grace period is over.
The 7-day grace period can be used again later after you purchase more licenses.
- If by the end of the grace period you don't purchase more licenses, the Parallels RAS farm will continue to operate normally as long as the number of concurrent users doesn't exceed the limit specified in your subscription.
- If the number of concurrent users exceeds the limit at any time, your Parallels RAS farm will be temporarily deactivated. This means that none of the users will be able to get the listing of published resources from the farm or use those resources.
Please note that deactivation may not happen as soon as the license overuse occurs, but it will happen within 1-2 hours.
To re-activate the farm, you have to make sure that the number of concurrent users doesn't exceed the license limit. Parallels RAS performs the validation every 20 minutes.
As soon as it detects that the number of concurrent users is at or below the limit, it will reactive the farm.
