Chapter 4 Performance and Sizing The TL895 Tape Library adds scalability for tape retention and performance demands. This powerful tape library is available in models using from two to seven drives, featuring high performance DLT 35/70 drives to fit any lights out enterprise backup solution needs. Compaq also developed industry leading performance tests that analyze the affects automated tape libraries have on enterprise based lights out backup solutions.
Adding TL895 Libraries to the Compaq Enterprise Backup Storage System Lights Out Tests Lights out tests were designed to consider factors that would affect backup rates when automated tape libraries are connected to the EBS. Tape retention policies determined the number of tapes needed to maintain several sets of backups that can be overwritten after the retention period has expired.
Performance and Sizing 31 Calculating Backup Windows ■ Volume Calculations--Backup windows can be set at virtually 24 hours per day with the EBS due to the use of a separate Storage Area Network (SAN) for data movement. However, many administrators prefer to schedule backups at off hours for management reasons. To calculate the time needed to perform various backup jobs, the backup rate, as defined in the Backup Formula section, must be compared to the data sets being backed up.
Adding TL895 Libraries to the Compaq Enterprise Backup Storage System Sizing Calculations Before you can begin the sizing process, you must have a thorough understanding of the network, the type of data to be backed up, and the back-up window parameters. The easiest and most precise way to size an Enterprise Backup System is to use the Compaq StorageWorks Enterprise Backup Solution sizer software, which may be obtained from the Internet at http://www.compaq.
Performance and Sizing 33 Sizing the Enterprise Backup Solution Speed Tests Determining the speed of Backup and Restore processes in a real-world environment is the most important factor in designing and implementing the Compaq StorageWorks EBS. Fibre Channel is designed to produce a theoretical maximum of 1.0625 Gigabits per hour. This equates to 100 Megabytes per second or 360 Gigabytes per hour. (Test results are expressed in GB/H for clarity).
Adding TL895 Libraries to the Compaq Enterprise Backup Storage System Restore rates also scaled near 1:1 with the same effect of compression and one additional factor. The maximum combined restore rate topped out at 90 GB/H for various numbers of drives and compression rates. NOTE: The test results were based on a controlled set of variables, but real-world data compression varies from file to file. The EBS Tech Note details test variables and other factors that can affect performance.
Performance and Sizing 35 Compaq StorageWorks Backup Sizing Tool Compaq developed a sizing tool that: ■ Allows easy input of the many variables that affect backup performance. ■ Calculates the number of tapes and libraries necessary to allow Lights Out operations. ■ Speeds calculations to ensure that backup windows are not exceeded. The tool allows selection of server configurations that can be replicated or modified to represent enterprise zones.
Adding TL895 Libraries to the Compaq Enterprise Backup Storage System Server Information Enter a server name and the estimated total Gigabytes of data to be backed up. Figure 4-4. Server Information screen Determining the Configured Primary Storage System The primary storage configuration is an important link in the backup performance calculation. It has a direct effect on the speed at which the server can send data to the tape device.
Performance and Sizing 37 Compressibility The compressibility screen allows specification of the type of backup data. Tests have shown that not all data can be compressed equally. The compression ratio will affect the amount of data that can be stored on each tape cartridge, as well as the speed at which the tape drives can read/write the data. If you have been performing tape backups on servers with DLT tape drives, you should already have a good idea of the expected compression ratio for your data.
Adding TL895 Libraries to the Compaq Enterprise Backup Storage System Selecting Software Options Choose the appropriate options for the server being configured. This information is used to select the software modules that are detailed in the solution. These options do not affect the performance calculations. The part numbers for selected items are displayed in the Solution and Summary screen.
Performance and Sizing 39 Specifying Tape Rotation and Partial Backups The Partial Backups screen allows you to enter the type of tape rotation to be used within each backup cycle. There are three basic types of tape rotation within each backup cycle. Each method offers advantages and disadvantages in cartridge use and restore time. Figure 4-7. Tape Rotation and Partial Backups screen For additional tape rotation information, see the sizer tool help screens.
Adding TL895 Libraries to the Compaq Enterprise Backup Storage System Schedule Information Screen The Schedule Information screen allows you to enter your backup schedule. Data to be Backed Up For each day of the week, specify the type of backup that will be performed. Selecting the only data that has changed option will refer to either differential or incremental backups as defined on the previous screen.
