Callout Description
Containers for storage resources (disk space, processing power, and network bandwidth). A pool can have one
or more members assigned to it.
A group can provide both block and le access to storage data. Access to block-level storage requires direct iSCSI access to PS
Series arrays (iSCSI initiator). Access to le storage requires the FS Series NAS appliance using NFS or SMB protocols and the Dell
FluidFS scale-out le system.
With storage data management features, you can:
• Manage a group through several built-in mechanisms such as ssh, serial line, telnet, and web-based user interfaces. You do not
need an external management station or management software.
• Congure the system to alert you to management activity or problems through log les, SNMP traps, and email notication
• Add more arrays (up to 16) to a group to increase capacity and performance
• Secure data and management access with authorization and authentication mechanisms
• Protect storage data with replication and snapshots
Borrowed Space Pane
The Borrowed Space pane displays information showing whether dierent objects on your system are using borrowed space and
how much space is being borrowed. This information can help you monitor space usage on your system and maintain your max-keep
policy.
The information appears under the Local Space and Remote Delegated Space tabs (see Table 68. Borrowed Space Pane, Table 69.
Local Space Tab, and Table 70. Remote Delegated Space Tab for more details). The panel at the top shows the most general
information. The lower panels show more specic information. The pie charts, tables, and bullet graphs in each panel show the same
type of information.
The links in the Activities pane change depending on what is selected under the tab.
Table 68. Borrowed Space Pane
Tab Description
Local Space Displays borrowing information for the following objects that can borrow space:
• Snapshots – Total amount of space borrowed for snapshots (middle table) and the
amount of space each volume’s snapshots are borrowing (bottom table)
• Replica sets – Total amount of space borrowed on this partner for inbound replica sets
(middle table) and the amount of space each volume’s replica set is borrowing (bottom
table)
• Local replicas – Total amount of space borrowed for local replicas of outbound replica
sets (middle table) and the amount of space each volume’s local replicas are borrowing
(bottom table)
• Deleted volumes – Total amount of space borrowed for deleted volumes (middle table)
and the amount of space each deleted volume is borrowing (bottom table)
Remote Delegated Space Displays borrowing information for the following objects that can borrow space:
• Replica sets – Total amount of space borrowed on the secondary partner for outbound
replica sets (top table) and the amount of space each replica set is borrowing (bottom
table)
