Integrated High Availability with vSphere

VMware HA, Application Monitoring API

• Monitors Critical Zimbra Services

• Sends heartbeat every 15 seconds

Protects all mail components

• MBS, MTA, LDAP, Proxy, Archive, +3rd Party

High Availability Setup

Step 1: start heartbeat on Zimbra VM

/opt/zimbra/libexec/vmware-heartbeat start

Step 3: enable app monitoring in vSphere Client

/etc/init.d/zimbra_heartbeat

Step 2 : add heartbeat to startup scripts

14

Integrated Business Continuity with vSphere

Choose your RPO

• ≥15 minutes – SRM with Host Based Replication

• < 15 minutes – SRM with 3rd party HW/SW replication

Protects all mail components

• MBS, MTA, LDAP, Proxy, Archive, +3rd Party

Test failover without production interruption

Fine to Coarse Grain Backups with vSphere

Item Level

• End user, Self service recovery

• Admin enabled/disabled

Mailbox Level

• D2D based built into Zimbra

• No 3rd party agents or software required

• Use 3rd party to vault to external media

VM Level

• Snapshot backups using VMware Data Recovery

• 3rd party HW/SW solutions using vStorage APIs

• Crash consistency built into Zimbra

Written in Java for high transactional throughput• Multiplex within single process, avoid process swapping and IPC

• Low CPU utilization at scale

Efficient storage architecture to support Large (>30GB) mailboxes

Zimbra with NetApp NFS on vSphere

10K user workload• 90 percent SOAP users, 10 percent IMAP users

• 21 receive/hour, 7 send/hour (per user)

• 120KB average message size

• 25% messages with 500KB attachment

• 100% Concurrency

Scale Out on vSphere 5

*Dell R910, 4 socket x 8 core x 2.27 GHz Xeon X7350 (Nehalem-EX), 256 GB

Result

• 21% host CPU utilization @ 32K users.

• Hypothesis: can double users per VM from 4K – 8K

Result

• 97% of Native performance!!

Guest OS improvements

• Dynamic hugepages allocated to applications (vs. fixed)

• Tickless timer with on demand interrupts (vs. periodic query)

Web Administration

ITaaS model

• Web Administration – multi-platform multi-browser

• Secure by design – application logging and monitoring

• Class of service – manage services and configuration

• Delegated Administrative model

• Multi-tenant / multi-domain by design

External LDAP / AD integration

• GAL per domain

• SSO authentication ( SPNEGO/Kerberos, SAML, Oauth) per domain

Compliance

• Zimbra Archiving and Discovery

• Legal Hold and Cross Mailbox Search

• Single Instance Storage Archive or Separate Server/Storage

Demo

26

Web Client Experience

Multi-platform / Multi-browser / Multi-Device

• Location and device independent

• AJAX / HTML5 (lead with the browser)

• Zimlets

Large Mailboxes

• Search

• Backend architecture (metadata and blob store separation)

• >30GB mailboxes

Demo

Key Takeaway's

1. Plug and Play with todays cloud infrastructure of choice, VMware vSphere.

2. Designed for massive scalability and mailboxes without boundaries.

3. Policy driven administration and extensibility with 3rd Party Applications and APIs.
