6.1.7 Release Notes 

Release: June 25, 2021

Fixes 

These issues have been fixed.

Cloud Block Store on AWS handles unreachable DNS servers (PURE-217655)
In order to ensure that a DNS server is always reachable, Cloud Block Store on AWS instances now forward amazonaws.com queries to Amazon’s DNS server at 169.254.169.253. All other queries are resolved by the DNS servers configured by the customer. If a Cloud Block Store instance cannot reach any of the user-configured DNS servers, vDrive failures are seen and eventually both controllers are taken offline.

Enhancements 

 
Increases the number of connected hosts for Cloud Block Store (PURE-224557)
The maximum connected host limit for Cloud Block Store on AWS and Cloud Block Store on Azure is raised to 300 hosts.
 

6.1.6 Release Notes

Release: May 7, 2021

Critical Fixes

These issues have been fixed.

Fixes

These issues have been fixed.

Updates Pure Cloud Block Store on AWS region support (PURE-222887)
Previously, Pure Cloud Block Store on AWS supported deployment in the sa-east-1 (South America - Sao Paulo) and eu-west-3 (Europe - Paris) regions.  With this release, those regions are no longer supported and will not show up as options for deployment.
 

Enhancements

 
Adds IO2 EBS volumes for improved performance (PURE-206710)
Introduces IO2 EBS volumes in newly deployed Cloud Block Store Virtual Drive instances, when available. This enhancement reduces cost and improves latency and durability.
Improves tags on cloud resources (PURE-200807)
In this Purity//FA 6.1.6 release, using CLI commands and RESTful API calls to addlist, and remove tags to all cloud resources has been added. These commands will be able to apply tag changes to all deployed cloud resources at once. 
 
The add and remove operations take approximately 5 minutes or more to finish, causing the commands to be asynchronous. Note that subsequent commands will be rejected if the previous commands are not finished. Thirty is the maximum number of tags that can be applied, however, the last tag from cloud resources cannot be removed, but overwriting the tag is acceptable. Currently, this new feature is only available for Cloud Block Store on AWS.

6.1.0 Release Notes

Release: December 21, 2020

New Features

 
Adds support for Cloud Block Store on Microsoft® Azure™ (PURE-121127)
Pure Cloud Block Store™ now delivers a software-defined storage solution natively in both AWS™ and Azure™ providing customers seamless data mobility and consistent user experience across hybrid and multi cloud. Cloud Block Store on Azure provides:
  • Low total cost of ownership: Cloud Block Store provides industry leading data reduction, deduplication, compression and thin provisioning to reduce cost of storage on public cloud.
  • Data Mobility: In addition to common data layer and consistent APIs across hybrid and multi cloud, Clock Block Store provides features such as async replication and Cloud Snap which make bidirectional data portability easy for users.
  • High availability: Cloud Block Store feature active cluster provides zero recovery time objective and zero recovery point objective across multiple availability zones and multiple regions.
  • Security: Always-on AES-256 data-at-rest encryption
Adds i3en support for virtual drive instances on Cloud Block Store on AWS //V20 (PURE-208063)
Adds support for i3en instances through our V20 SKU. i3en instances offer both cost and performance benefits, in lower cost per terabyte and better write latency characteristics. The V10 SKU continues to use i3 instances in the 6.1.0 release.
Supports suspending a Cloud Block Store on AWS array (PURE-162029)
Adds the CLI purearray suspend command to support suspending operation of a Cloud Block Store on AWS array and de-provisioning the associated compute and NVRAM resources. Upon resuming via a provided lambda, the array re-provisions resources and begins serving I/O again. Suspended arrays are reflected as such in Pure1 Manage.

Security Update

Enhancements

 
New permission requirements for Cloud Block Store on AWS (PURE-193290, PURE-193792)
For Cloud Block Store on AWS, the following permissions must be added to the "PurityServiceRole" before upgrading to this release:
ec2:CreateLaunchTemplate
ec2:CreateLaunchTemplateVersion
ec2:DeleteLaunchTemplate
ec2:DescribeLaunchTemplates
ec2:DescribeLaunchTemplateVersions
These requirements are added to the appendix section of the Cloud Block Store Deployment and Configuration Guide for AWS.
Note: To require an IMDSv2 security token in all instance metadata requests, Cloud Block Store on AWS adds the ec2:ModifyInstanceMetadataOptions permission to the shared controller and vDrive instance policy. (No customer action is required.)

Fixes

These issues have been fixed.

Addresses an erroneous failed status report on Cloud Block Store on AWS vDrives (PURE-195974)
In a very rare case when reconnecting to a vDrive on Cloud Block Store on AWS arrays, puredrive list incorrectly marks the drive as failed even though the drive is healthy.

Command Line Interface Changes

Purity 6.1.0 incurred the following CLI changes:

Command Change Description
