Introduction HP Open Source Middleware Stacks (OSMS) offer building block applications, such as the Web Server; technical blueprints, and documents such as this MySQL Sizing Guide which describes the maximum MySQL workload that HP ProLiant c-Class Blade Servers are capable of supporting; and consulting services to speed the successful implementation of an open source strategy.

Typographic Conventions This document uses the following typographic conventions. Command ComputerOut Ctrl-x ENVIRONVAR [ERRORNAME] Key Term UserInput VARIABLE \ (continuation character) ... | A command name or qualified command phrase. Text displayed by the computer. A key sequence. A sequence such as Ctrl-x indicates that you must hold down the key labeled Ctrl while you press another key or button. The name of an environment variable, for example, PATH.
Benchmark Software The SysBench test suite is an open source, cross-platform, multi-threaded benchmark tool for evaluating system performance when running a database under a heavy load.

Table 4 SysBench Options SysBench option Value Description --test oltp OLTP emulates operations that a read database would perform. Other options are CPU, threads, mutex, memory, and fileio. --oltp-table-size 1000000 Sets the number of rows in the test table. --mysql-engine-trx yes Sets the value for whether the storage engine used is transactional. --oltp-test-mode complex Determines how transactions are performed.
Table 6 MySQL Test Configuration (continued) mysqld Option Value Description join_buffer_size 1M Buffer size for joins that do not use indices and require a full table scan. thread_cache_size 16 Number of server threads to cache for reuse. thread_stack 192K Per-thread stack size. The default is 192K. query_cache_size 0 Amount of memory allocated for caching query results. The value “0” disables query cache. ft_min_word_len 4 Minimum length of the word to be included in a full-text index.
Depending on whether the application requires many read/write queries, it may help to set the database connection pool to the number of processing cores. For read-only testing, all HP Proliant c-Class Blade Servers in the test can still handle almost the same number of transactions even though the number of concurrent threads is double the number of processing cores. Therefore, more database connections than the number of processing cores for read-only applications can be used.

Figure 4 SysBench Results for the HP ProLiant BL685c Server Summary The results of the SysBench testing indicated that the HP Proliant c-Class Blade Servers provide a solid platform for the MySQL database server. Along with the integrated Smart Array controller these servers provide the security of RAID storage to the host operating system and database files, while also offering excellent performance for many applications.
