Published on

This Webinar features Jessie Bryan (Dir. of Systems Engineering at Impulse Advanced Communications) and discusses the high-availability capabilities in NexentaStor, including:

- eliminating a single point of failure with active-active fail-over to a standby system
- establishing fail-over groups and implementing highly cost-effective disaster recovery
- achieving zero data loss and downtime with half the complexity
- automating and non-disruptively testing fail-over / fail-back via NexentaStor
- setting up manual and automated fail-over of critical applications and services in a clustered environment

Finally, learn how Impulse - a communications provider focused on voice and data services - leverages the Nexenta-certified Pogo Linux StorageDirector Z2 HA Cluster SAN solution to deliver continuity of their services to customers.

  • IntroIntro to what Paul (Director of Engineering) will be covering –.Very Brief on Southampton University lesson. Campus Cluster HA not a cure all for poor IT procedures. It&apos;s very much additive to best practice as a lead into next slide on causes.
  • VeryBrief acknowledgement on causes of downtime. Make the case for the bigger the system, the multiplier of MTBF’s means that planning outage prevention and necessity not a nice to have.....oh and having HA capability can even help with the planned outages.
  • Use casesLast 17 years, RSF-1 exposure in most verticals, platforms and a myriad of applications (need to add real names to slide)Whether it is the acess control to the Tokyo Stock Exchange, the high throughput transaction processing Credit Card authorisation systems, life savingEmergency Ambulance Command and Control systems or a just placating a grouchy CEO&apos;s by keeping his email up, the cluster product at the heart of the NexenentaStor HA plugin, has been delivering system availability in some of the most demanding situations.
  • 2 Appliances currentlyMultiple Volumes and VIPSShared Storage ArchitectureActive /Active or Active/PassiveMultiple heartbeat interconnectsRobust data fencing mechanismSupported protocols and hardwareSome of the key points and benefits.... on to the various configurations
  • ....... EitherOk well that’s all I wanted to cover, so now lets hear from one of Pogo’s customers Jesse Bryan, Director of Systems Engineering forImpulse Advanced Communications to talk about a real customer case study using NexentaStor and the HA Plugin.Jesse.OR if Sakthi wants to be “Master of Ceremonies” then OK Sakthi, that’s all I wanted to cover. Thank you.

    56. 56. Campus Cluster<br />Imagine separating them over distance – Campus Cluster<br />Typical University HA Cluster combine with DR<br />Relies on fibre connectivity (possible use of Dark Fibre over long Distance BUT Expensive !!)<br />
    57. 57. Metro Cluster<br />Separation over distance<br />Typical Disaster Recovery usage NOT High Availability<br />Rely on single Heartbeat Type e.g. ATA over Ethernet, Dark Fibre - manual ONLY - <br />
