As storage continues to grow in your environment, it is important to know how your storage is performing and that it is tiered correctly in order to reduce costs. The latest on-premises release of IBM Spectrum Control™ (IBM® Tivoli® Storage Productivity Center), a member of the IBM Spectrum Storage™ family, is now available. It is full of consumer oriented features and enhancements that provide the ability to monitor and manage your storage infrastructure efficiently. To download the release, see Fix Central

 

With this new release, the IBM Spectrum Control™ development team continued to pay attention to what you want and how you want to monitor your storage systems by centralizing, simplifying, and optimizing storage tasks that are associated with your storage systems.

Some of the highlights for the new release include:

Added support for monitoring the IBM Spectrum Scale™  storage system New support for monitoring the IBM FlashSystem™  V9000 storage system Simplified optimization views for tiering storage and balancing pools Increased fabric management support Viewing cache performance metrics for IBM System Storage® SAN Volume Controller, IBM Storwize®, and IBM FlashSystem storage systems

 

Monitoring IBM Spectrum Scale storage systems

IBM Spectrum Scale™, formerly known as IBM General Parallel File System (GPFS™), is a software defined storage solution that processes large amounts of data in a distributed environment on a single GPFS cluster. IBM Spectrum Scale is a member of the IBM Spectrum Storage™ family.

For more information, see the IBM Spectrum Storage product page.

In V5.2.6, you can add an IBM Spectrum Scale storage system without specifying a user that has root privileges. Before you add the storage system for monitoring, you must add the user to the sudoers file on the GPFS cluster node that is used for authentication:

Add the set of administration commands that are required to monitor the storage system. Associate the user with the set of administration commands.

For more detailed information, see Monitoring IBM Spectrum Scale without requiring root privileges.

You can now see more information about the inode usage for your filesets.

The Overview page for storage systems has new charts that show the following information about inode usage:

The filesets with the least number of free inodes The filesets with the largest number of total inodes

In addition, you can view dependencies between GPFS clusters. You can view information about the following monitored resources:

GPFS clusters that share file systems with the storage system

On the Related Resources/GPFS Clusters page, the Shared File Systems column shows the number of file systems shared between the clusters.

When you click a value in the Shared File Systems column, the new File Systems page opens that provides details about the file systems shared between the two clusters. It shows information like the name of the file system on the owning cluster, the name of the file system on the cluster mounting it remotely, and the number of nodes mounting the file system on any GPFS cluster known to IBM Spectrum Control.

 

File systems that are remotely mounted from related GPFS clusters

When you click on a value in Nodes Mounting column of the new File Systems page, the properties page of the corresponding file system opens with the information for Nodes Mounting tab. It shows, in detail, which nodes on which GPFS cluster have the file system that is currently mounted (for example, had it mounted the last time IBM Spectrum Control probed the clusters).

You can also view all the nodes across all the monitored clusters that mount a file system. Three new columns were added to the File Systems overlay page for the IBM Spectrum Scale:

IBM FlashSystem V9000 monitoring

The IBM FlashSystem V9000 storage system is now available for monitoring in IBM Spectrum Control.

As always, in order to monitor a storage system in IBM Spectrum Control, you must configure a connection to the storage system and schedule the collection of data. A probe is run automatically to collect status and asset information about the storage system.

The V9000 Flash modules are visible as managed disks in IBM Spectrum Control. If you want to be automatically notified when certain conditions are detected for FlashSystem V9000 storage system or any supported storage system, you must view the alert definitions for that resource. For example, to view the alert definitions for a FlashSystem V9000 storage system, go to Storage > Storage Systems, right-click the FlashSystem V9000 storage system, and select Edit Alert Definitions. The default alerts are enabled automatically for the storage system after you access the Edit Alert Definitions page.

For a complete list of the versions of storage systems and CIM agents that you can add, see the Supported Storage Products Matrix for IBM Spectrum Control.

 

Simplified optimization views for tiering storage and balancing pools

The purpose of analyzing tiering is to tier volumes based on the I/O rate or I/O density thresholds that you set. Depending on the conditions that are set, recommendations are generated.

You can reduce storage costs by moving volumes with low workloads from higher and more expensive tiers to lower and less expensive tiers. Storage performance can be improved and used more efficiently by moving volumes with heavy workloads to the tiers that meet the workload requirements of the volumes.

When you implement the recommendations, you ensure that the volumes are placed on the tiers that best match the workload requirements of the volumes.

IBM Spectrum Control has made it easier to define the thresholds that determine the placement of volumes and the thresholds that prevent re-tiered volumes from overloading destination pools.

image

 

You can define two types of thresholds, I/O rate or I/O density rate, which determine whether a volume is up-tiered or down-tiered. To ensure that pools do not become overloaded when volumes are added, you define maximum I/O rates for the pools on each tier.

You balance pools to distribute volume workload across pools on the same tier in your storage environment. Now, all that you need do to balance pools is right-click two or more pools on the same tier and same storage virtualizer, and click Balance Pools.

Increased fabric management support

You can view information about Cisco NPV switches from the Fabrics 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 with the Internal Routes tab:

NPV switches are switches that are configured to work in N_Port Virtualization (NPV) mode. NPV switches use N_Port ID Virtualization (NPIV) technology to allow multiple logical connections to a fabric switch port.

 

The following figure shows an NPV switch on the NPV Switches page:

Viewing cache performance metrics for IBM System Storage SAN Volume Controller, IBM Storwize, and IBM FlashSystem storage systems

You can now view performance metrics for the new cache architecture that was introduced in SAN Volume Controller V7.3. For example, you can view new metrics for the volume cache and the volume copy cache.

image

 

These performance metric updates are available for SAN Volume Controller, Storwize, and FlashSystem block storage systems whose firmware version is V7.3 or later. In addition, there are new MDisk cache metrics.
