12. 12 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, +3 rd Party VMware ESX VMware ESXi Resource Pool Failed ServerOperating Server Critical Zimbra Services X

13. 13 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. 14 Integrated Business Continuity with vSphere  Choose your RPO ≥15 minutes – SRM with Host Based Replication < 15 minutes – SRM with 3 rd party HW/SW replication  Protects all mail components MBS, MTA, LDAP, Proxy, Archive, +3 rd Party  Test failover without production interruption VMware vSphere Site Recovery Manager Site A (Primary) Site B (Recovery) Servers Z MTA Z MBS Z Proxy Z LDA P

15. 15 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 3 rd party agents or software required Use 3 rd party to vault to external media  VM Level Snapshot backups using VMware Data Recovery 3 rd party HW/SW solutions using vStorage APIs Crash consistency built into Zimbra

17. 17 3Rd Party Storage System Zimbra Primary DB Index Zimbra Journaling Mailbox Server (MBS) Architecture – Cloud Scale Zimbra Collaboration Server Message and File Store APIMeta DataSearch Database Reliability Zimbra Secondary HSM  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

18. 18 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 PrimarySecondaryJournalIndexDB Capacity10-20%80-90% Primary ÷ 15 Primary × 35% 5MB per mbx IOPS/user0.030.010.02 0.06 (w/ attachments) 0.04 IO PatternWrite/ReadRead/WriteWriteWrite/ReadRead/Write  Workload Requirements 60-70% write IO for MBS 1700 IOPS total for MBS 200 IOPS total for MTA server Detailed MBS Storage Profile

19. 19 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

20. 20 4K – 8K Performance Comparison Number of vCPUs Memory size (GB) Number of Users Sendmail latency (ms) CPU utilization (usr/sys/wait) 4324,000112.518.8/3.4/9.1 8648,000119.017.7/3.2/9.4 4328,000167.338.6/6.6/20.8  Result Same compute resource footprint, double the users Well within performance tolerance levels

23. 23 Admin and User Experience Virtualization Operations User Experience Anywhere Access Application Cloud Scalability Hardware Independence

24. 24 Simple Provisioning on VMware vSphere  NEW* Multi-instance Appliance  Install to Inbox in minutes  No OS installation or administration

25. 25 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

26. 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

27. 27 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 3 rd Party Applications and APIs.
