After a storage space is defined, you can start adding
storage services to the space.
About this task
Storage services contain one or more physical storage pools. In addition to storage
capacity, a service has a set of capabilities, defining the storage quality, such as thin/thick
provisioning, compression, encryption, etc.
The services that you add become available for the
solution components included in the Spectrum Control Base package (see Included cloud interfaces). When provisioning storage, the end users consume it from the
spaces and services without dealing underlying physical storage infrastructure.
You can add
each individual storage service separately, as described in the following procedure.
Procedure
In the Spaces tab of the Spaces/Storage Services pane, select a space on
which you want to create a new service.
Click Add button on the Spaces/Storage Services pane. The New Storage Service dialog box is displayed.Figure 1. New Storage Service dialog box
Use the Select Capability drop-down box to define the new service
attributes and their values. See table below for details.
Important: Spectrum Control Base uses dynamic filtering to simplify selection of a
storage system and a resource, which provides the best match for selected service attributes. When a
service is created, Spectrum Control Base groups the best matching storage systems in the left
section of the Storage Systems pane. Also, the matching storage resources are grouped at the top of
the respective storage system. In addition, storage system and resources that do not support the
selected service attributes are grayed out in the bar view or removed from the list in the table
view.
Table 1. Service parameters
Parameter
Description and values
Name
Alphanumeric string for service identification. This is a mandatory field. The
service name must not contain spaces.
Description
Alphanumeric string for service description.
Encryption
Enables encryption for the service. If enabled, you can attach only encrypted
storage resource to the service.
Flash
Enables utilization of a storage resource, located on a flash-based storage
resource. This can be one of the following storage systems: FlashSystem 900, FlashSystem V9000, Storwize® Family.
Space Efficiency
Enables storage space efficiency features for the service. When selected, you
can configure the service to be attached to a thick- or thin-provisioned storage
resource.
Configuration considerations
When adding a VVol-enabled service, define its
space efficiency during VM provisioning via the vSphere web client. To allow this, disable space
efficiency in Spectrum Control Base.
QoS
Enables the use of the Quality of Service (QoS) feature for the service. QoS
is applicable to volumes (Max Independent Performance) or storage resources (Max Shared
Performance), setting the IOPS and bandwidth limits within the following ranges:
IOPS: 0-100000
BW (bandwidth): 0-10000 MB/s
Currently, the QoS capability is not available for IBM SAN Volume Controller (SVC) storage
systems or Spectrum Accelerate Family products, using the domain administrator storage
credentials.
Availability
Enables the use of IBM HA technology for highly-available storage deployments
IBM SAN Volume Controller (SVC) storage systems. Select the Stretched option to use volumes
stretched across different sites. The Regular option makes use of volumes located on a single
site.
Data Reduction
Enables the use IBM
Real-time Compression™ with or without data
deduplication.
Configuration considerations
A service with enabled IBM
Real-time Compression will be able to support
the compression-compatible (thin-provisioned) storage resources on XIV® and Spectrum Accelerate systems. For the FlashSystem V9000, Storwize Family storage systems,
a storage resource must have the data compression enabled prior to service attachment (via product
CLI or GUI).
Currently, DS8000® storage systems do not
support IBM
Real-time Compression.
VVol Service
Enables virtual volume functionality for the service.
The virtual volume
functionality is supported by the IBM
XIV (11.5.1 or later) and storage systems that run IBM Spectrum Virtualize™ (7.6 or later).
An XIV VVol-enabled service does not support IBM
Real-time Compression.
Click Create to finish the procedure. A new service is added to the current Spaces tab.
You can edit the service properties by right-clicking a service which you want modify, and then
selecting Modify Properties.
