Improving Reliability, Agility, and Manageability in Cohesity Pegasus 6.1.1

By Christian Paulus • December 19, 2018

It is almost the end of the year, but before we pop the champagne and start the fireworks, we would like to give you a holiday gift by providing you with important new capabilities in our Pegasus 6.1.1 release. The release improves reliability, agility, and manageability of your deployments with a granular pay-as-you grow model and faster compliance.

It is never more apparent that we live in a 24×7 business world than at the holidays. For today’s business, being always on and having data instantly accessible is no longer a nice to have, but a requirement. With this in mind, Cohesity now supports 2-node fault tolerance so that your system can withstand the failure of two random nodes in clusters with greater than 4 nodes. Your cluster will operate without degradation by distributing the workloads to the other nodes. The trend amongst our enterprise customers is to increase the number of nodes in a single cluster, rather than installing multiple smaller sized clusters.  As clusters get bigger the impact increases in case of a node failure. With 2-node fault tolerance we improve resilience in even the largest clusters.

Two-node fault tolerance is a unique capability further improving our already strong resilience capabilities, including a fully distributed architecture with no single point of failure, strict consistency, erasure coding, and replication factor.

Other benefits provided to you as part of the 6.1.1 release include:

Agility and ease-of-use to meet compliance requirements

In the Pegasus 6.1 launch blog post we announced our support for WORM (Write Once Read Many) to enable the security officer role to create and apply a datalock policy to selected jobs. With the new Legal Hold capability, we go a step further to cover a slightly different situation: Here an organization anticipates litigation requirements to preserve all forms of relevant information. The security officer role can apply a datalock on selected job runs or underlying objects for an indefinite period until the security officer role lifts the lock. WORM and Legal Hold are important capabilities to help organizations meet compliance requirements.

Higher flexibility for storage capacity

Web scale is all about being able to start with the resources you need and add as your requirements gow. In this vein, Cohesity has now certified Cisco UCS 3260 at 210 TB (21 x 10 TB) and HPE Apollo 4510 at 200TB (25 X 8 TB) to provide the flexibility to start with an initial “half-shelf” capacity for your cluster and add incremental capacity in the future. The initial node capacity (half or full chassis) is known at the cluster installation time and is accurately reflected in alerts for intended cluster / node capacity and disk count.

Increase agility with native Cisco HyperFlex integration

Cisco HyperFlex integrates with the Cohesity software-defined platform on Cisco UCS using native sentinel snapshots. The joint Cisco-Cohesity solution consolidates primary and secondary data and apps, respectively, for greater simplicity, visibility, agility, and access across clouds. The HyperFlex snapshot integration offers several benefits including reduced stun times for app-consistent backup, agentless app-aware backup, improved backup performance, and lower RTO and near-instant RPO.

Increased visibility to service providers and tenants

Recently, we announced the ability for managed service providers to create multiple tenant spaces on a Cohesity platform. We are now iterating fast to add more reports tenants can use. The new reports will give tenants finer-grained understanding of their usage, whether past protection runs were successful, and which of their objects are protected. For service providers, many of the default reports now have the capability of a selection of a single organization or multiple organizations for specific data points to provide more granular visibility about a specific organization running on their system(s).

Simplified Oracle RAC data protection

The majority of enterprises run their Oracle DB deployment in the Real Application Cluster (RAC) configuration for high availability. We are now supporting the Oracle RAC configuration in Beta. The various management tasks are scheduled centrally and the process is automated so that there is no need for manual intervention or scripts, which greatly simplifies data protection.

The 6.1.1 release contains a long list of additional capabilities and enhancements. Some of the new capabilities will soon be launched separately so please stay tuned. If you are an existing customer and want to learn more please check out the release notes. And as always, please reach out to us if you are curious how we can enable your secondary data use case in a hybrid cloud environment.

I wish you a merry Xmas and a happy new year!
