Management Interfaces; Ds8000 Storage Management Gui - IBM DS8900F Introduction And Planning Manual

You can configure and manage this allocation method by using the DS8000 Storage Management GUI and
DS CLI.
Rotate volumes allocation method
Volume extents can be allocated sequentially. In this case, all extents are taken from the same array until
there are enough extents for the requested volume size or the array is full, in which case the allocation
continues with the next array in the pool.
If more than one volume is created in one operation, the allocation for each volume starts in another
array. You might want to consider this allocation method when you prefer to manage performance
manually. The workload of one volume is allocated to one array. This method makes the identification of
performance bottlenecks easier; however, by putting all the volume data onto just one array, you might
introduce a bottleneck, depending on your actual workload.
Managed allocation method
When a volume is managed by Easy Tier, the allocation method of the volume is referred to as managed.
Easy Tier allocates the capacity in ways that might differ from both the rotate capacity and rotate volume
allocation methods.

Management interfaces

You can use various IBM storage management interfaces to manage your storage system.
These interfaces include DS8000 Storage Management GUI, DS Command-Line Interface (DS CLI), the DS
Open Application Programming Interface, DS8000 RESTful API, IBM Spectrum Controland IBM Copy
Services Manager.

DS8000 Storage Management GUI

Use the DS8000 Storage Management GUI to configure and manage storage, and to monitor performance
and Copy Services functions.
DS8000 Storage Management GUI is a web-based GUI that is installed on the Hardware Management
Console (HMC). You can access the DS8000 Storage Management GUI from any network-attached
system by using a supported web browser. For a list of supported browsers, see "DS8000 Storage
Management GUI web browser support and configuration" on page 20.
You can access the DS8000 Storage Management GUI from a browser by using the following web
address, where HMC_IP is the IP address or host name of the HMC.
https://HMC_IP
If the DS8000 Storage Management GUI does not display as anticipated, clear the cache for your
browser, and try to log in again.
Notes:
• If the storage system is configured for NIST SP 800-131A security conformance, a version of Java that
is NIST SP 800-131A compliant must be installed on all systems that run the DS8000 Storage
Management GUI. For more information about security requirements, see information about configuring
your environment for NIST SP 800-131A compliance in the IBM DS8000 series online product
documentation ( http://www.ibm.com/support/knowledgecenter/ST5GLJ_8.1.0/
com.ibm.storage.ssic.help.doc/f2c_securitybp.html).
• User names and passwords are encrypted for HTTPS protocol. You cannot access the DS8000 Storage
Management GUI over the non-secure HTTP protocol (port 8451).
