Integrated High Availability with v. Sphere § 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 X Critical Zimbra Services Resource Pool 12 VMware ESXi Operating Server Failed Server Operating Server

High Availability Setup Step 1: start heartbeat on Zimbra VM /opt/zimbra/libexec/vmware-heartbeat start Step 2 : add heartbeat to startup scripts /etc/init. d/zimbra_heartbeat Step 3: enable app monitoring in v. Sphere Client 13

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

Fine to Coarse Grain Backups with v. Sphere § Item Level • End user, Self service recovery • Admin enabled/disabled § Mailbox Level • D 2 D 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 v. Storage APIs • Crash consistency built into Zimbra 15

Zimbra Application Architecture User Experience Anywhere Access Application Cloud Scalability Virtualization Operations Hardware Independence 16

Mailbox Server (MBS) Architecture – Cloud Scale § 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 (>30 GB) mailboxes Zimbra Collaboration Server Message and File Store API 3 Rd Party Storage System Zimbra Primary Zimbra Secondary HSM 17 Database Reliability Zimbra Journaling Search Meta Data Index DB

Zimbra with Net. App NFS on v. Sphere § 10 K user workload • • • § Workload Requirements 90 percent SOAP users, 10 percent IMAP users • 60 -70% write IO for MBS • 1700 IOPS total for MBS • 200 IOPS total for MTA server 21 receive/hour, 7 send/hour (per user) 120 KB average message size 25% messages with 500 KB attachment 100% Concurrency Detailed MBS Storage Profile Primary Secondary Journal Index DB 10 -20% 80 -90% Primary ÷ 15 Primary × 35% 5 MB per mbx IOPS/user 0. 03 0. 01 0. 02 0. 06 0. 04 IO Pattern Write/Read/Write Capacity 18 (w/ attachments) Write/Read/Write

Scale Out on v. Sphere 5 § Result • 21% host CPU utilization @ 32 K users. • Hypothesis: can double users per VM from 4 K – 8 K *Dell R 910, 4 socket x 8 core x 2. 27 GHz Xeon X 7350 (Nehalem-EX), 256 GB 19

4 K – 8 K Performance Comparison § Result • Same compute resource footprint, double the users • Well within performance tolerance levels 20 Number of v. CPUs Memory size (GB) Number of Users Sendmail latency (ms) CPU utilization (usr/sys/wait) 4 32 4, 000 112. 5 18. 8/3. 4/9. 1 8 64 8, 000 119. 0 17. 7/3. 2/9. 4 4 32 8, 000 167. 3 38. 6/6. 6/20. 8

Virtual vs. Native Performance Comparison § Result • 97% of Native performance!! § Guest OS improvements • Dynamic hugepages allocated to applications (vs. fixed) • Tickless timer with on demand interrupts (vs. periodic query) 21 Number of CPUs Number of Users Virtual/Native Sendmail latency (ms) CPU utilization (usr/sys/wait) 4 4, 000 Virtual 112. 5 18. 8/3. 4/9. 1 4 4, 000 Native 112 17. 5/3. 8/11 8 8, 000 Virtual 119 17. 7/3. 2/9. 4 8 8, 000 Native 115 20. 3/3. 4/9. 7 Number of v.
