Causes for Downtime

High Availability

• RSF-1 first commercial HA solution for UNIX• Heritage in enterprise Solaris/Oracle• 15+ year proven track record• Global installed base – worldwide resellers• KISS design ethos• Constantly evolving – osmosis of proven

features • HA Cluster plugin for NexentaStor

– V2.0 – NMC/NMS - Initial release basic functionality– V3.0 – NMV/NMC/NMS – Much better integration– V3.1 – Usability Release

High Availability Plugin for NexentaStor

HA Cluster Plug-in• 2 Appliances currently• Multiple Volumes & VIP’s• Shared Storage Architecture• Active / Active (or Active / Passive if you like!)• Multiple heartbeats & Multiple Types (Disk, NW, Serial)• Robust data fencing mechanisms (mhdc, VIP check, heartbeat redundancy)• Supports Protocols & Hardware CIFS, NFS, iSCSI, FC• Supports SAS, SATA (+certified interposers), FC, SCSI, AoE. iSCSI• Client volume access via virtual IP(s) and or COMSTAR targets

Key Points & Benefits• Volume runs on only one appliance at a time • Failover initiated in seconds• Fencing ensures data integrity - Prime concern (no split brain possible)• Ease of use (2 volume cluster creation < 1 minute)• Simple but Scalable• Seamless integration with NexentaStor• Minimal administration

Typical HA Cluster for NexentaStor – e.g. Pogo Linux Storage Director

Integrated Appliance

•

Logically the same cluster – mirrored disk arrays

Traditional HA pair – separate co-located appliances

Mirrored Arrays

Expanded 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 !!)

Campus 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 -

Metro Cluster

The Business Value of NexentaStor for High Availability

Company Overview• Impulse Advanced Communications was founded in 1996 and is based

out of Santa Barbara, Calif.• Leading B2B Service Provider of voice and data network solutions –

including FailSafe Internet Access, hosted VoIP, managed hosting & network design

About Me• Jessie Bryan, Director of Systems Engineering• Oversees two primary data centers located in Santa Barbara, Calif. –

serving 10,000 Zimbra Mailboxes, 5,000 websites, 4,000 hosted VoIP seats

Impulse Advanced Communications - Overview

• Scenario / Infrastructure– IBM BladeCenters powered by VMware ESXi hosted in Impulse’s Santa

Barbara data center– 250+ servers – featuring 18 Zimbra Email, Web & Calendar Servers

• Workload– Serving over 10,000+ Zimbra Mailboxes, 5,000 websites, 4,000 VoIP cfgs– Highly-Accessible, Always-on Business-Critical Services– Data Protection: Nightly Zimbra Back-ups, Managed Router cfg Back-ups

• Previous Storage Platform– Backend SAN: NetApp Filer 2000-2006

• Cost-prohibitive scale-out solution as business needs out-grew capacity• Unable to keep up with I/O load; caused poor performance

– Backend SAN: EMC Celerra 2006-2010• Network bandwidth too low – 2GB/sec throughput limitation• Storage costs per gigabyte almost 10x more than NexentaStor solution

The Business Value of NexentaStor for High AvailabilityMeet growing storage needs without consuming entire IT budget

The Business Value of NexentaStor for High Availability

Storage needs• Enterprise-grade SAN without the price

• Scale-out solution that isn’t cost-prohibitive

• High availability to hosted services while eliminating a single-point of failure

• Support for VMware ESX

Storage solution• Rich feature-set Open Storage solution that tops legacy SAN technologies

• Cost-effective scalability, as business needs grow

• Active/Active failover for always-on access to data

• VMware-Ready Solution

Our NexentaStor deployment architecture

The Business Value of Nexenta for High AvailabilityNexentaStor 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.

• Use Nexenta Professional Services. If you don’t have open storage expertise the resources come very handy

• Test and document Failover scenarios. Cannot over emphasize this!

• 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– Quorom disk 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
