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.

Webinar Date: March 15th, 2011

  • 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'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'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.

  • ....... 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.

    • 45. Robust data fencing mechanisms (mhdc, VIP check, heartbeat redundancy)
    • 46. Supports Protocols & Hardware CIFS, NFS, iSCSI, FC
    • 47. Supports SAS, SATA (+certified interposers), FC, SCSI, AoE. iSCSI
    • 48. Client volume access via virtual IP(s) and or COMSTAR targets
    Key Points & Benefits
    • Volume runs on only one appliance at a time
    • 49. Failover initiated in seconds
    • 50. Fencing ensures data integrity - Prime concern (no split brain possible)
    • 51. Ease of use (2 volume cluster creation < 1 minute)
    • 52. Simple but Scalable
    • 53. Seamless integration with NexentaStor
    • 54. Minimal administration
  • Integrated Appliance
    Typical HA Cluster for NexentaStor – e.g. Pogo Linux Storage Director
  • 55. Expanded Cluster
    Mirrored Arrays
    Logically the same cluster – mirrored disk arrays
    Traditional HA pair – separate co-located appliances
  • 56. Campus Cluster
    Imagine separating them over distance – Campus Cluster
    Typical University HA Cluster combine with DR
    Relies on fibre connectivity (possible use of Dark Fibre over long Distance BUT Expensive !!)
  • 57. Metro Cluster
    Separation over distance
    Typical Disaster Recovery usage NOT High Availability
    Rely on single Heartbeat Type e.g. ATA over Ethernet, Dark Fibre - manual ONLY -
  • 58. Hybrid Cluster
    Forced
    Manual
    Auto
    Replication
    Replication
    Primary Pair
    Secondary
    Primary Site Full HA Active / Active Cluster
    Secondary DR site Manual failover (Restricted HA Licence)
    Typical Emergency Services HA Cluster with DR Configuration

  • The Business Value of Nexenta for High Availability
    NexentaStor HA Cluster Best Practiices
    • Use Nexenta certified / tested hardware. Certified solutions have gone through the rigorous testing and QA by Nexenta. This hugely minimizes risks involved in deploying the complete solution.
    • 80. Use Nexenta Professional Services. If you don’t have open storage expertise the resources come very handy
    • 81. Test and document Failover scenarios. Cannot over emphasize this!
  • The Business Value of NexentaStor for High Availability
    Deployment Considerations – our recommendations
    Headnode Interconnections
    Crossover cable between the nodes for Heartbeat
    ssh-bind between the nodes on crossover or managed network for sharing configuration and passing commands 
    Shared External SAS storage
    Quoromdisk for shared configuration and file locking
    SAS SSDs or SAS Disks for shared write log(zlog) and/or cache(l2arc) 
    Use aggregate network ports for redundancy
    Dedicate NAS network traffic; separate management network
    External JBOD for Basic HA configurations
