- The GPFS Ambari integration package is now called the IBM Spectrum <br>
Scale Ambari management pack (in short, management pack or MPack). <br>
- IBM Spectrum Scale Ambari management pack version 2.4.2.1 with <br>
HDFS Transparency version 2.7.3.1 supports BI 4.2/BI 4.2.5 IOP migration
<br>
to HDP 2.6.2. <br>
- Supports the remote mount configuration in Ambari. <br>
- Supports the multiple file systems configuration. In management <br>
pack version 2.4.2.1, the current limit is two file systems. <br>
- The Short circuit write is supported for better performance. <br>
- In HDFS Transparency, the Ranger performance is enhanced. <o:p></o:p></span></span></p>

<p><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:9.0pt">IBM Spectrum Scale GUI changes
<o:p></o:p></span></span></p>
<p><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:9.0pt"> - Added new Networks page to monitor the performance, configuration, and
<br>
adapters of network configurations in the cluster. You can monitor the <br>
network performance with respect to the IP and RDMA interfaces used in the configuration.
<br>
- Added new Monitoring > Thresholds page to create and monitor the threshold rules
<br>
that are defined in the system. <br>
- Added Access > Remote Connections page to enable the GUI node of the <br>
local cluster to monitor the remote cluster by establishing a connection <br>
with the GUI node of the remote cluster. <br>
- Added Settings > Call Home page to configure call home. Configuring <br>
the call home feature helps the IBM® Support to monitor the system. <br>
Configuring call home also helps to reduce the response time of the <br>
IBM Support to resolve any issues. <br>
The diagnostic data that is downloaded through the Settings > Diagnostic Data
<br>
can be uploaded to a problem management record (PMR) by using <br>
the call home feature in the backend. To upload the diagnostic data, right-click
<br>
the relevant data set from the Previously Collected Diagnostic Data, and <br>
select Upload to PMR. <br>
- Added file system creation capabilities in GUI. Use the Files > File Systems > Create File System
<br>
option to launch the Create File System wizard. In the Create File System wizard, you can specify
<br>
the following details of the file system: <br>
- File system name <br>
- Storage pools <br>
- NSDs for the file systems <br>
- Failure groups <br>
- NSD order for data writes <br>
- Maximum number of Spectrum Scale clients <br>
- Maximum number of inodes of the root fileset <br>
- Whether to enable quota and scope for the quota definition <br>
- Whether to enable DMAPI <br>
- Mount point and automatic mount mode <br>
- Added the aggregation levels Access Point and Filesets and removed Account <br>
for the resource type Transparent Cloud Tiering in the Monitoring > Statisitics page.
<br>
- The Files > Transparent Cloud Tiering page now displays the file systems <br>
and filesets that are mapped with the cloud service. It also shows the <br>
connection of such a container pair configuration to a cloud account and <br>
the corresponding CSAP that is configured for the cloud account. <br>
- Changes to capacity monitoring in the GUI <br>
- Moved the Capacity page from Monitoring to Files menu in the navigation
<br>
and renamed the GUI page to User Capacity. <br>
- Only the file data user capacity can be viewed from the Files > User Capacity page.
<br>
Removed the pools, filesets, file system capacity monitoring options from the Files > User Capacity page.
<br>
You can monitor the capacity of these components from the respective GUI pages.
<br>
- Replaced the GPFSPoolCap sensor with the GPFSPool sensor and separate data and metadata
<br>
level capacity monitoring are introduced in the performance charts available in the
<o:p></o:p></span></span></p>
<p><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:9.0pt"> Files > File Systems and Storage > Pools pages.
<br>
- New GPFSPool-based data and metadata performance monitoring metrics are available
<br>
for selection in the Files > Statistics > Edit > Capacity section. <br>
You need to select the aggregation level as Pool to view these metrics.
<br>
- AFM monitoring changes in the GUI <br>
- Provides the number of AFM filesets and the corresponding export server maps.
<br>
Each export map establishes a mapping between the gateway node and the NFS
<br>
host name to allow parallel data transfers from cache to home. <br>
- By using the Request Access option available in the Files > Active File Management
<br>
or Access > Remote Connection page in the GUI, you can now establish connection with remote clusters.
<br>
After establishing the connection, you can monitor the following AFM and AFM DR
<br>
configuration details across clusters: <br>
* On home and secondary, you can see the AFM relationships configuration,
<br>
health status, and performance values of the Cache and Disaster Recovery grids.
<br>
* On the Overview tab of the detailed view, the available home and secondary inodes are available.
<br>
* On the Overview tab of the detailed view, the details such as NFS throughput,
<br>
IOPs, and latency details are available, if the protocol is NFS. <br>
- New option to create AFM peer snapshots through GUI. Use the Create Peer Snapshot option
<br>
in the Files > Snapshots page to create peer snapshots. You can view and delete these peer snapshots from
<br>
the Snapshots page and also from the detailed view of the Files > Active File Management page.

<p><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:9.0pt">File data: Block and subblock sizes improve I/O performance and reduce fragmentation
<o:p></o:p></span></span></p>
<p><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:9.0pt"> The default block size is larger, 4 MiB instead of 256 KiB, and the sizes of subblocks relative to blocks
<br>
s are smaller, for example, 8 KiB subblocks in a 4 MiB block. A larger block size improves the
<br>
file system performance and a smaller subblock size reduces the amount of unused space. For many business
<br>
applications, the default value of 4 MiB provides the best balance of improved performance
<br>
and reduced fragmentation. <o:p></o:p></span></span></p>
