Nodes option shows attributes for appliances: Requires 11.1.1 or higher

The Nodes option in the 11.1.1 version of the Grid Manager now lists attributes for StorageGRID Webscale appliances, such as hardware, networking, and storage information.
Note: For version 11.1.0, continue to access this information by selecting Support > Grid Toplogy > appliance Storage Node > SSM > Resources.

Instructions added for estimating time to complete an upgrade

To provide guidance on the time to allow for an upgrade, the topic, "Estimating the time to complete an upgrade" has been added.

User interface changes

Several enhancements have been made to the StorageGRID Webscale user interface, which you will notice when you first sign in to version 11.1:
  • A new Nodes option has been added to the Grid Manager main menu. You can select the tabs on the new Nodes page to view charts and tables that summarize how your system is performing and to see information about each node, including unacknowledged alarms, CPU utilization, networking summary, storage, and events. Object and ILM information is provided for Storage Nodes.

    All of the detailed service and attribute information previously available from the Grid page continues to be available from a new Support > Grid Topology page. The new Support menu also includes the Logs and AutoSupport options.

  • The Grid Management Interface has been renamed as the Grid Manager.
  • The Tenant Management Interface has been renamed as the Tenant Manager.

Compliance support for S3 buckets

StorageGRID Webscale 11.1 adds support to help S3 tenant account users comply with the record keeping requirements of governmental agencies such as the U.S. Securities and Exchange Commission (SEC) and the U.S. Commodity Futures Trading Commission (CFTC). The new compliance feature allows S3 tenants to comply with regulations that require object data to be preserved for a specified amount of time.

Grid administrators must first enable this functionality for the entire StorageGRID Webscale system by enabling the global Compliance setting. Then, S3 bucket owners can create compliant buckets using the S3 API, the Tenant Manager, or the Tenant Management API. Settings for compliant buckets allow users to specify the retention period for objects in the bucket, place a bucket under a legal hold, remove a legal hold, and determine whether objects are automatically deleted when their retention periods expire.

Objects in compliant buckets are evaluated by compliant rules in the active ILM policy: these rules ensure that at least two replicated copies or an erasure-coded copy of each object is maintained on Storage Nodes for the length of the retention period.

Improvements to software upgrade procedure

Improvements have been made to the software upgrade procedure in StorageGRID Webscale 11.1 to make upgrading to a new release faster and easier. Update packages are distributed to grid nodes in parallel, and you can upgrade one grid node of each type in parallel. In addition, the upgrade progress is reported for each node, so you can more readily discern where issues might be occurring.

The upgrade changes go into effect after you upgrade the primary Admin Node to StorageGRID Webscale 11.1.

New hotfix procedure

After upgrading to StorageGRID Webscale 11.1, you can apply StorageGRID Webscale hotfixes with an easy-to-use interface on the Grid Manager. Select Maintenance > Apply Hotfix.

Changes to metadata space and alarms

Changes have been made to how StorageGRID Webscale manages and reports on the available space for object metadata.
  • For new installations, the value for Metadata Reserved Space (CAWM) on storage volume 0 has been increased from 2 TB to 3 TB. This increase helps to ensure that each Storage Node has adequate space available for essential database operations, such as compaction.
    Note: After you upgrade to StorageGRID Webscale 11.1, you should increase the value manually to 3 TB if sufficient space exists on all Storage Nodes.

    Upgrading StorageGRID Webscale > "Increasing the Metadata Reserved Space watermark"

  • The calculations for the Metadata Used Space (Percent) (CDLP) alarm have been modified, so you will know sooner if you need to add new Storage Nodes. The CDLP alarm is now triggered when the portion of Metadata Reserved Space that is available for object metadata reaches 70% full (minor alarm), 90% full (major alarm), and 100% full (critical alarm).
  • When the Metadata Used Space (Percent) alarm reaches the 90% threshold, a warning appears on the Dashboard, making it more obvious when you need to add new Storage Nodes.

Enhancements to S3 and Swift REST API support

The following changes have been made:
  • S3 and Swift: A new grid-wide option, HTTP, allows you to use HTTP instead of HTTPS for communications between Storage Nodes and API Gateway Nodes. For example, you might prefer to use HTTP during testing. If the HTTP option has been enabled for the grid, you must use different ports for HTTP communications than for HTTPS communications.
  • S3 only: You can now issue cross-origin resource sharing (CORS) requests for S3 buckets. To manage CORS, you can use the S3 REST API, the Tenant Manager, or the Tenant Management API.

Platform services improvements

S3 requests requiring CloudMirror replication, event notifications, or the search integration service are now automatically throttled to match the rate outgoing to the endpoint. This allows up to 100 active tenants to use platform services. You can now also configure an HTTP proxy for platform services to reach the internet. In addition, you no longer need to contact your NetApp representative before using platform services.

Support for decommissioning disconnected nodes

Previously, if a StorageGRID Webscale system included any grid nodes with a status of Unknown or Administratively Down, you could not decommission any of the connected grid nodes. With the release of StorageGRID Webscale 11.1, you can now decommission grid nodes while they are disconnected.

SGA Maintenance Mode for StorageGRID Appliance Installer

You can now place the compute controller in a StorageGRID Webscale appliance into maintenance mode, instead of shutting it down. Maintenance mode makes performing maintenance procedures, including firmware upgrades, on the storage controller less disruptive because you no longer need to access the appliance hardware to reapply power.
