SPECmail2009: New World record on T5240 1.6GHz Sun 7310 and ZFS

The Sun SPARC Enterprise T5240 server running the Sun Java Messaging server 7.2 achieved a World Record SPECmail2009 result using Sun Storage 7310 Unified Storage System and ZFS file system.  Sun's OpenStorage platforms enable another world record.

  • World record SPECmail2009 benchmark using the Sun SPARC Enterprise T5240 server (two 1.6GHz UltraSPARC T2 Plus), Sun Communications Suite 7, Solaris 10, and the Sun Storage 7310 Unified Storage System achieved 14,500 SPECmail_Ent2009 users at 69,857 Sessions/Hour.

  • This SPECmail2009 benchmark result clearly demonstrates that the Sun Messaging Server 7.2, Solaris 10 and ZFS solution can support a large, enterprise level IMAP mail server environment as a low cost 'Sun on Sun' solution, delivering the best performance and maximizing data integrity and availability of Sun Open Storage and ZFS.

  • The Sun SPARC Enterprise T5240 server supported 2.4 times more users with 2.4 times better sessions/hour rate than AppleXserv3 solution on the SPECmail2009 benchmark.

  • There are no IBM Power6 results on this benchmark.

  • The configuration using Sun OpenStorage outperformed all previous results with traditional direct attached storage and significantly higher number of disk devices.

Benchmark Description

The SPECmail2009 benchmark measures the ability of corporate e-mail systems to meet today's demanding e-mail users over fast corporate local area networks (LAN). The SPECmail2009 benchmark simulates corporate mail server workloads that range from 250 to 10,000 or more users, using industry standard SMTP and IMAP4 protocols. This e-mail server benchmark creates client workloads based on a 40,000 user corporation, and uses folder and message MIME structures that include both traditional office documents and a variety of rich media content. The benchmark also adds support for encrypted network connections using industry standard SSL v3.0 and TLS 1.0 technology. SPECmail2009 replaces all versions of SPECmail2008, first released in August 2008. The results from the two benchmarks are not comparable.

Software on one or more client machines generates a benchmark load for a System Under Test (SUT) and measures the SUT response times. A SUT can be a mail server running on a single system or a cluster of systems.

A SPECmail2009 'run' simulates a 100% load level associated with the specific number of users, as defined in the configuration file. The mail server must maintain a specific Quality of Service (QoS) at the 100% load level to produce a valid benchmark result. If the mail server does maintain the specified QoS at the 100% load level, the performance of the mail server is reported as SPECmail_Ent2009 SMTP and IMAP Users at SPECmail2009 Sessions per hour. The SPECmail_Ent2009 users at SPECmail2009 Sessions per Hour metric reflects the unique workload combination for a SPEC IMAP4 user.

Key Points and Best Practices

  • Each Sun Storage 7310 Unified Storage System was configured with one J4400 JBOD array with 22x1TB SATA drives to a mirrored device and 4 shared volumes are built under the mirrored device. Total 8 mirrored volumes from 2 x Sun Storage 7310 are mounted on the system under test (SUT) messaging mail indexes and mail messages file system using NFSV4 protocol. Four SSDs were used as the SUT internal disks. Each SSD is configured as a ZFS file system. Four such ZFS directories are used for the messaging server queue, store metadata, LDAP and queue. SSDs substantially reduced the store metadata and queue latencies.

  • Each Sun Storage 7310 Unified Storage System was connected to the SUT via a dual 10-Gigabit Ethernet Fiber XFP card.

  • The Sun Storage 7310 Unified Storage System software version is 2009.08.11,1-0.

  • The clients used these Java options: java -d64 -Xms4096m -Xmx4096m -XX:+AggressiveHeap

  • Substantial performance improvement and scalability was observed with Sun Communications Suite7 update2, Java Messaging Server 7.2 and Directory Server 6.2

  • See the SPEC Report for all OS, network and messaging server tunings.
