User Share Assignments
Examples ◆ [User1, 1] [GroupB, 1]
Assigns 2 shares: 1 to User1, and 1 to be shared by the users in GroupB.
Each user in GroupB has equal importance. User1 is as important as all the
users in GroupB put together.
In this example, it doesn’t matter if the number of shares is 1, 6 or 600. As
long as User1 and GroupB are both assigned the same number of shares,
the relationship stays the same.
◆ [User1, 10] [GroupB@, 1]
If GroupB contains 10 users, assigns 20 shares in total: 10 to User1, and 1
to each user in GroupB. Each user in GroupB has equal importance. User1
is ten times as important as any user in GroupB.
◆ [User1, 10] [User2, 9] [others, 8]
Assigns 27 shares: 10 to User1, 9 to User2, and 8 to the remaining users,
as a group. User1 is slightly more important than User2. Each of the
remaining users has equal importance.
❖ If there are 3 users in total, the single remaining user has all 8 shares,
and is almost as important as User1 and User2.
❖ If there are 12 users in total, then 10 users compete for those 8 shares,
and each of them is significantly less important than User1 and User2.
◆ [User1, 10] [User2, 6] [default, 4]
The relative percentage of shares held by a user will change, depending
on the number of users who are granted shares by default.
❖ If there are 3 users in total, assigns 20 shares: 10 to User1, 6 to User2,
and 4 to the remaining user. User1 has half of the available resources
(5 shares out of 10).
❖ If there are 12 users in total, assigns 56 shares: 10 to User1, 6 to User2,
and 4 to each of the remaining 10 users. User1 has about a fifth of the
available resources (5 shares out of 56).
