Symantec today announced the release of Storage Foundation 6.1 and Cluster Server 6.1. This release enables organizations to adopt Flash/SSD for mission-critical workloads for increased and reliable performance without compromising on availability. This release also further enhances the high-availability and disaster recovery capabilities which our customers already use.

 

New features in this release include:

  • SmartIO - Granular, online caching at the application level. With SmartIO, application architects, server administrators, and database administrators can move reads and writes inside the server. In lab tests replicating real-world use-cases, SmartIO delivers up to 400% performance improvement while reducing storage costs by 80%.
  • Flexible Storage Sharing (FSS) - Simplify SSD/Flash adoption and realize...

Disaster Recovery Orchestrator now supports Amazon Web Services(AWS) as a failover target. With today's new release for Disaster Recovery Orchestrator, you can choose between Microsoft Azure and AWS as your target environment for disaster recovery. We provide the same benefits and features irrespective of which cloud provider you decide to go with. Businesses can automate and manage disaster recovery of Microsoft Windows based applications residing on either physical or virtual machines to the public cloud; targeting the cloud for disaster recovery helps in significantly reduce costs while achieving stringent Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).

SmartIO was introduced in Storage Foundation HA 6.1. SmartIO enables data efficiency on your SSDs through I/O caching. Using SmartIO to improve efficiency, you can optimize the cost per Input/Output Operations Per Second (IOPS). SmartIO supports both read and write-back caching for the VxFS file systems that are mounted on VxVM volumes, in multiple caching modes and configurations. SmartIO also supports block-level read caching for applications running on VxVM volumes.

The SmartIO Blueprints for Linux and Windows give an overview of the benefits of using SmartIO technology, the underlying technology, and the essential configuration steps to configure it.

In the SmartIO Deployment Guide for Linux, multiple deployment scenarios of SmartIO and how to manage them are covered in detail.

The SmartIO assessment guide discusses how to analyze the impact of SmartIO and various performance statistics....

There are several aspects that prove that Storage Foundation is an enterprise storage management tool that has been used for years on the most critical environments. Recently I had the opportunity to use the NetApp EF550 all flash array with Storage Foundation Cluster File System (CFS). Both products are a perfect fit, as the design of CFS can maximize the all flash array performance.

The topic I want to cover here is the usual gap between storage and server admins, and how Storage Foundation can help fill that gap. Storage admins always do their best to provide the appropriate storage to meet the SLA required by applications. The server admins have to consume that storage. I have found many cases in the field where LUNs are not correctly mapped, which may result in risking data protection and/or performance issues resulting when storage with incorrect characteristics (such as RAID levels) has been provisioned.

The NetApp EF550 array offers a nice tool to create the...

I recently ran across an article by Robin Harris of StorageMojo that took an interesting take on the long term futures of DAS and SAN.

I would recommend that you read the article, but in summation, Mr. Harris looked at the advancement of network interconnects as a key factor in the increasing adoption of DAS.  More specifically, that the price and specs of 10gbE have remained stagnant, making the extreme OPEX and CAPEX investments for network upgrades a tough proposition.  This becomes even more evident when you look at the CPU and back-plane improvements (PCIe for instance) over the past few years and couple those improvements with the relative ease in upgrading compute and internal bus against replacing an entire Edge/Core network.

This was an interesting angle that I hadn’t considered as we developed and released our DAS focused capabilities in...

Version 6.1 for VOM (Veritas Operations Manager) has been released recently. This new version brings management capabilities for Cluster File System and Flexible Storage Sharing (FSS) environments. In this blog entry I will highlight how to start using VOM to manage FSS and how to create a new volume.

Before being able to manage FSS it is necessary to upgrade the Managed Host (MH) version in the cluster nodes. The reason is that CFS 6.1 comes with a package that does not include the new capabilities from VOM in order to manage FSS. You can check your MH version clicking on the Settings icon and then on Hosts. You should see the list of all Cluster Hosts managed through VOM.  If the cluster is not currently added to VOM for management then you can click on Add Host and add the nodes. The MH Version column will show what is the Managed Host...

Think about all the things you need to do in your data center to keep the business happy. Manage multi-vendor storage arrays in your SAN, introduce and manage new SSD/Flash arrays whether in server/ in SAN/ or as DAS, support increasing storage requests from multiple cost centers without approvals to buy new storage.. and that’s only on the storage side. What about having visibility across your physical and virtual environments, managing high availability and disaster recovery scenarios including failover and testing, and finally having the ability to create reports that you can feed back to business based on their needs?

Veritas Operations Manager provides a single standard interface for solutions under the Symantec Storage Foundation High Availability suite of products. With the latest 6.1 release, Veritas Operations Manager now includes the following for your ease of use:

Flexible Storage Sharing (FSS) – Improved visibility and management for...

Following the announcement during Vision 2014, we have launched Disaster Recovery Orchestrator! Disaster Recovery Orchestrator enables businesses to automate and manage disaster recovery of Microsoft Windows based applications residing on either physical or virtual machines to Microsoft Azure cloud. Using Disaster Recovery Orchestrator to target the cloud for disaster recovery can significantly reduce costs while achieving stringent Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).

Is the era of storage systems (arrays) facing disruption? Do the expensive monolithic chassis sellers need to find new ways to make money? Do the investors betting on newer storage array startups need to cash in now? Although it may feel unlikely in the near term, the perfect storm may not be that far away.

Let us think about how storage arrays came to solve problems for IT. There were two distinct transformations in this industry:

  1. In the beginning, storage systems originated as a way to offload computing requirements for RAID (Redundant Array of Independent Disks) from the host. In the days when hard drives had only a few gigabytes of capacity, data centers needed a purpose-built solution that had the computing power to implement RAID solutions on spinning disks. It was common to see such storage systems directly connected to servers hosting...

“What is SmartIO and what does it do?”  Since the launch of Storage Foundation 6.1, I’ve been asked that question by all sorts of people in all sorts of situations.  The most concise answer I have is that “SmartIO makes everything in a SAN faster”.  In a two-minute conversation with a customer or family member, this answer is typically enough, especially for the less technically inclined members of my family.  For those curious or dubious however, the next question is always “what do you mean everything?”

The first place SmartIO brings value is in application performance, specifically those with lots of small, random reads and writes, such as a transactional database.  By keeping hot data inside the server on super fast solid state devices, application reads are filled in microseconds rather than milliseconds on traditional SAN.
