Logical
The Logical section is introduced as a part of the new modernized interface of IBM Storage Insights to provide details of the associated internal storage resources for the selected storage system. The I/O groups, Managed disks, Pools, RAID arrays, Volumes, and Volume groups pages are grouped under the Storage section. By accessing the pages, users can see the storage system-specific resources without browsing back to the classic UI.
The following pages are available under the Logical section.
I/O groups
Each pair of nodes within a single enclosure is known as an input/output (I/O) group. The I/O groups page displays the details of associated I/O groups with the selected storage system. The page displays the I/O groups and Performance tabs.
The Name, Nodes, Enclosures, Volumes, FC Ports, Compression, Mirroring Memory (MB), FlashCopy Memory (MB), and Remote Copy Memory (MB) columns are the default columns that are shown in the I/O Groups tab. For more information, see I/O groups.
Managed disks
A managed disk is storage that is virtualized by a storage virtualizer. A managed disk can represent a volume that is assigned from a back-end storage system. The disk can also represent one or more physical disks that are installed locally in a storage virtualizer. One or more managed disks can be added to a pool or managed disk group, from which volumes are allocated and assigned to host servers. The page displays the details of managed disks that are associated with the storage system.
The page displays the Managed disks, Performance, and Capacity tabs.
The Name, Status, Pool, Storage System, Mode, Easy Tier, Easy Tier Load, Used Capacity, Available Capacity (GiB), Class, RAID Level, Volumes, Back-end Storage System, Back-end Pool, and Back-end Volume are the default columns that are shown in the Managed disks tab. For more information, see Managed disks, external volumes, and array LUNs.
Pools
A storage pool is a grouping of storage that consists of volumes, logical unit numbers (LUNs), or addresses that share a common set of administrative characteristics. The page displays the details of associated storage pools with the selected storage system. The page displays the Pools, Performance, and Capacity tabs.
The Name, Storage System, Status, Tier, Used Capacity (%), Total Compression Ratio, Available Capacity (GiB), Capacity-to-Limit (GiB), Recent Fill Rate (%), Usable Capacity (GiB), Shortfall (%), Volumes, Pool Attributes, Managed Disks, and Tier Distribution (%) are the default columns that are displayed in the Pools tab. For more information, see Pools, aggregates, and common provisioning groups.
RAID arrays
The page displays the details of the RAID arrays that are associated with the storage system. The page displays the RAID arrays and Capacity tabs.
The Name, Status, Pool, RAID Level, Capacity (GiB), DDM Capacity (GB), DDM Speed (Rational Portfolio Manager), DDM Class, Compression Savings (%), Encryption, and Compressed are the default columns show in the RAID arrays tab. For more information, see RAID arrays.
Volumes
The page displays the details of the volumes that are associated with the storage system. The page displays the Volumes, Performance, and Capacity tabs.
The Name, Pool, Status, Copy ID, Capacity (GiB), Used Capacity (%), Threat Detection Timestamp, Used Capacity (GiB), Written Capacity (%), Written Capacity (GiB), Hosts, Compression Savings (%), Tier Distribution (%), and Volume Group are the default columns that are shown in the Volumes tab. For more information, see Volumes.
Volume groups
A volume group is a container for managing a set of related volumes as a single object. The page displays the details of the volume groups that are associated with the storage system. The page displays the Volume groups, Performance, and Capacity tabs.
The Name, Volumes, Replication Policy, Replication State, Current Recovery Point, Snapshot Policy, Snapshot Written Capacity (%), Policy Status, and Snapshots are the default columns that are shown in the Volume groups tab. For more information, see Volume groups.
