Because this represents a transactional workload, the InnoDB storage engine was used for the MySQL database server. Four different servers from the HP ProLiant family were used for each of the OLTP tests. Each test was performed using read-only queries and then with read/write queries and a varied number of connections.
Table 2 Test Hardware Environment (continued) Hardware BL460c File System (ext3 – no LVM): Partitioning Disk0: /, /boot, swap Disk1: FC attach – 7 36GB disks 10k RPM, RAID 0 Operating RHEL5 AS u1 SMP System kernel (2.6.18-53.el5) with errata updates SysBench Configuration The OLTP test mode emulates real database usage by issuing common SQL queries on typical table structures.
Table 4 SysBench Options SysBench option Value --test oltp --oltp-table-size 1000000 --mysql-engine-trx --oltp-test-mode complex --oltp-read-only . on/off --oltp-dist-type special --max-requests --num-threads varied from 1 to 128 --init-rng --max-time MySQL Installation The MySQL Certified Software, downloaded from the MySQL Network, provides the mysql-enterprise-gpl-5.0.46-0.rhel5.x86_64.tar file for RHEL5 on x86_64 servers.

If an application requires 1200 read/write tps from 16 database connections, all of the HP Proliant c-Class Blade Servers used in these tests are suitable because all of the test servers can handle at least 1245 tps.
Figure 1 SysBench Results for the HP ProLiant BL460c Server HP Proliant BL465c Server The HP ProLiant BL465c server is a two-way server blade designed for maximum compute density and power efficiencies. The small form factor accommodates two blades in each slot allowing for 16 servers in a standard 6u enclosure.
Figure 2 SysBench Results for the HP ProLiant BL465c Server HP Proliant BL480c Server The HP ProLiant BL480c server is a 2-way server blade designed for maximum performance and scalability. The ProLiant BL480c server can support two Quad-Core Inter Xeon processors, which gives the equivalent of eight processing units per server.
8000 Series processors, 64GB of DDR2 memory, two hot-plug Serial Attached SCSI (SAS) or Serial ATA (SATA) hard-drives, four embedded Gigabit NICs, and three I/O expansion slots, the HP ProLiant BL685c delivers the density you want with the performance you need to handle the most demanding enterprise class applications.
The test results indicated that optimum price and performance could be achieved using a MySQL Replication configuration with a pair of HP ProLiant BL460c or BL480c servers with 8 cores in a high-availability cluster where HP Proliant c-Class Blade Servers acted as the MySQL master database server.
