Role-Based Access Control

Role-Based Access Control (RBAC) is a mechanism for managing a

set of actions (capabilities) that a user or administrator can performon a storage system.

A role is created.

Capabilities are granted to the role.

Groups are assigned to one or more roles.

Users are assigned to groups.

CapabilitiesRolesGroups



Disks and Data Protection

Spares are global.

Raid Group 0 Spares

Volume 1

DataData DataParity



Aggregates

Represent thephysicalstorage

Made up of one or more RAID groups

A RAID group:

One or more data disks

Parity disks

RAID 4 has only one parity disk

RAID-DP has two parity disks

Data is striped for parity protection Volumes are allocated space from an

aggregate



How Aggregates and FlexVol Volumes

Work

Create RAID Groups

Create aggregate

RAID groups are

created as result

Create FlexVol 1

Only metadata space is

used

There is no preallocation

of blocks to a specific

volume Create FlexVol 2

WAFL allocates

aggregate space as

data is written Po ulate volumes

Active version of X is now composed of blocks A, B, C

Snapshot version of X remains composed of blocks A, B, C

Atomically moves active data to new consistent state

Qtrees

A qtree is a logically defined file system that

exists as a special subdirectory at the root of a

volume. Qtrees allow:

Partitioning of data within a volume

Special quota requirements Limitation

The maximum number of qtrees per volume is

4,995
