Start of changeIBM Spectrum Control, Version 5.2.8

New for IBM Spectrum Control Version 5.2.8

New features and enhancements are available in IBM Spectrum Control™ Version 5.2.8.

The following features and enhancements are available for all product licenses:

Name change for IBM® Tivoli® Storage Productivity Center to IBM Spectrum Control
Beginning with Version 5.2.8, IBM Tivoli Storage Productivity Center is now IBM Spectrum Control, part of the IBM Spectrum Storage™ family. To access the documentation for IBM Tivoli Storage Productivity Center 5.2.7 and earlier, go to http://www.ibm.com/support/knowledgecenter/SSNE44/.
Comprehensive improvements to alerting capabilities
The ability to define alerts and be notified of capacity changes, configuration changes, and performance conditions on resources is significantly enhanced.
Applying a more extensive set of alert conditions to detect problems
You can now define alerts for all the key attributes of a resource, including attributes for status, configuration, capacity, and performance. Use this extensive set of new alert conditions to better monitor and identify more of the critical situations in your environment.
For example, in previous versions of alerting, there were just a few capacity-related conditions for storage systems. In this release, there over 50 that you can alert on, including conditions like Used Capacity, Total Volume Capacity, and Available Pool Space. For performance alerts, you can now alert on any of the hundreds of metrics that are collected by IBM Spectrum Control.
Customizing how often you receive alerts
To avoid receiving too many emails and disruptive notifications for some alerts, you can now choose a new suppression option where only one notification is sent. This new option, and all the existing suppression options, are also now available for all alerts, not just performance alerts.
Setting up multiple alerts for the same attribute
If you want to define more than one alert for the same attribute but with different criteria and settings, you can duplicate that alert. Duplicating alerts can be helpful in the following situations:
  • When you want to generate separate warning alerts and critical alerts for different conditions on the same attribute.
  • When you want to send alert notifications to different people based on the severity of an alert.
The following figure shows the alert definitions for the performance of a storage system port, including multiple alerts for the same metric that are triggered based on different conditions:
See Alerting and event processing.
Monitoring IBM Spectrum Scale™ performance
You can now view the performance of clusters, nodes, and file systems in IBM Spectrum Scale. For example, you can:
  • Analyze the performance of multiple clusters over a period to determine which clusters have the heaviest I/O loads or the longest response times
  • View which of the nodes that mount a file system have the heaviest I/O loads, highest CPU loads, or highest memory usage
  • Compare the file systems on a cluster to determine which file systems have the heaviest I/O loads and the longest response times

The following figure shows a performance chart for two file systems on the File Systems page:

Monitoring object storage systems
You can now monitor object storage systems on IBM Spectrum Scale. For example, you can:
  • View the GPFS™ file system that is associated with the object storage system. Combined with the ability to view the relationship between IBM Spectrum Scale and its SAN-attached storage, you can now troubleshoot all the resource connections in the data path. For example, if you are troubleshooting an object storage problem, you can view the file system that is used by an object container and then view the back-end storage systems that are used by the file system.
  • View capacity and space usage for object storage systems and for specific accounts and containers.
  • Monitor the object count and space quotas for accounts and containers.
  • Plan for capacity by reviewing the capacity growth of GPFS clusters that are used for object storage.

The following figure shows capacity and usage information for object storage systems on the Object Storage Systems page.

Monitoring IBM FlashSystem™ 840 and IBM FlashSystem 900 storage systems
You can now monitor the capacity and space usage of IBM FlashSystem 840 and IBM FlashSystem 900 storage systems.
Viewing capacity charts for pools

Capacity and space usage for pools

You can now view charts that show the current and historical capacity of your block storage pools. To check when the available space will run out, based on the historical capacity and space usage trends for the pool, see the value that is shown in the Zero Capacity column.
Operating system requirements for IBM Spectrum Control
IBM Spectrum Control is now a native, 64-bit application for all server operating systems. You can no longer use the IBM Spectrum Control server on 32-bit operating systems. Every application that is included with the server components is now a 64-bit application. The storage resource agents for Microsoft Windows, IBM AIX®, and Linux (excluding the IBM Power® and IBM zSeries architectures) are also native 64-bit applications. They can no longer be used on 32-bit operating systems.
SNMP Version 3 support for switches
IBM Spectrum Control now supports Simple Network Management Protocol (SNMP) Version 3 as the preferred protocol for the management of switches and fabrics from Cisco Systems, Inc., and as an optional protocol for devices from Brocade Communications Systems, Inc. and other vendors. Storage Resource agents are no longer used as data sources for switches and fabrics. Using Network Advisor as a Common Information Model (CIM) agent remains the preferred option for managing Brocade switches and fabrics. Probes, zone control, and performance management of Cisco switches and fabrics are now carried out by using SNMP only. For devices from Brocade and other vendors, the existing SNMP and CIM technology is still supported.
SNMPv3 adds encryption and authentication capabilities to the SNMPv1 model and provides a secure environment for the management of storage resources.
See Agent types for switch and fabric functions and Adding fabrics and switches for further details about support and configuration of switches and fabrics.
For planning considerations, see Planning IBM Spectrum Control migration to SNMP.
If you are migrating switches to SNMP from a proprietary agent technology, see Migrating Cisco fabric and switch data sources to SNMP.
Viewing performance information about inter-switch connections
You can view information about the performance of inter-switch connections on the Inter-Switch Connections page. Click the Performance tab to display the performance information, as shown in the following figure.

Viewing information about Brocade Access Gateway switches
Brocade switches that are configured to work in Access Gateway mode and Cisco switches that are configured to work in N_Port Virtualization (NPV) mode are referred to as NPV switches. NPV switches use N_Port ID Virtualization (NPIV) technology to allow multiple logical connections to a fabric switch port.
You can view information about Brocade switches that are in Access Gateway mode from the NPV Switches page. You can also view information about the routes from ports that are connected to a hypervisor, server, or storage system to ports that are connected to fabrics. You can view the internal routes from Fibre Channel ports to proxy node ports, that is, from F_ports to NP_ports.
The following figure shows the type of information that you can view for a Brocade switch that is in Access Gateway mode:

Viewing information about Brocade F_port trunks and NPV links
An F_port trunk is a logical aggregation of NPV links between a native mode Brocade switch and a Brocade Access Gateway. An NPV link is a link between a native mode fabric switch and a Brocade switch that is in Access Gateway mode. You can view information about Brocade F_port trunks and about NPV links on the Inter-Switch Connections page.
The following figure shows an F_port trunk and an NPV link on the Inter-Switch Connections page.

Identifying problems on resources
You can now more easily identify the internal resources that are encountering problems in your environment. To do this, the condition of top-level resources such as storage systems, servers, hypervisors, fabrics, and switches is shown separately from the status of their internal resources.
Condition Status

Condition represents the most critical status that was detected on a resource itself and on its internal resources. For example, if an error status is detected on a disk, the overall condition of its storage system is error.

Condition is shown on the Dashboard view and on resource list pages and provides an at-a-glance, snapshot of the health of your resources.

Status represents the status of a resource as reported by its own hardware. For example, if a disk on a storage system is disconnected, an error status is reported for that disk by the storage system.

Status is shown on the detail pages for a resource and helps you identify the specific resources that are causing the problems in a top-level resource.

See Monitoring the status and condition of resources.
Checking the capacity that is managed by IBM Spectrum Control
You can go to Settings > Managed Capacity to compare how much capacity is managed by IBM Spectrum Control with the total amount of capacity that you are entitled to manage.
Checking the capacity and distribution of volume extents in pools that use Easy Tier®
On the Pools page and on the Volumes page, you can now see information about the capacity for each of the class drives (SSD, Nearline HDD, and Enterprise HDD), that Easy Tier can use to tier or distribute volume extents. You can also see the distribution of the volume extents across each Easy Tier drive class or tier in the pool, such as the percentage of volume extents on SSD drives, on Enterprise HDD drives, and on Nearline HHD drives.
Enhanced support for products and platforms
The following new products and platforms are supported:
  • You can now monitor IBM Spectrum Scale version 4.2 storage systems.
  • You can use Brocade virtual fabrics with IBM Spectrum Control, with some limitations. See Planning for Brocade management agents.
Stand-alone GUI removal

To consolidate the functions of IBM Spectrum Control into a single GUI, the stand-alone GUI is being removed in this release. Some functions of the stand-alone GUI were moved into the web-based GUI, such as the ability to add and monitor vCenter servers and NetApp filers, and remove fabrics. However, other functions, such as file system scans, policy management, the topology viewer, database monitoring, and user, rollup, and batch reports, are no longer available in version 5.2.8.

If you are currently using any of these functions in the stand-alone GUI, ensure that you take a snapshot of your data and set up similar data collection schedules and alerting definitions in the web-based GUI before you upgrade.
