Chapter 1: Introduction • WebPAM Components (page 2) • How They Work Together (page 2) • PAM Installation Options (page 3) • About This Manual (page 5) Thank you for purchasing a Promise Technology RAID Controller product. This Web-based Promise Array Management (WebPAM) browser-based software is included to improve your RAID Monitoring and Management experience. Figure 1. WebPAM in a browser window For more information about the WebPAM Graphic User Interface (GUI), see Chapter 4 on page 29.
WebPAM User Manual WebPAM Components There are two components to WebPAM. Depending on your installation, all three may be on the same workstation or work separately across your network: Utility Server – The Utility Server runs on the “Host PC”. The Utility Server software monitors and reports on the condition of the RAID logical drives and provides a complete set of management tools. It displays a Graphic User Interface (GUI) on your Internet Browser.

A drive that used to be present but is suddenly absent is the failed disk drive. No drive on Port 3 Port 1 Port 2 Port 4 In this example, there were four disk drives connected to the FastTrak Controller. Notice that there is no drive on Port 3. This is the failed drive.

WebPAM User Manual RAID 0 – Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple disk drives. Performance is increased, since the workload is balanced between drives or “members” that form the logical drive. Identical drives are recommended for performance as well as data storage efficiency. The logical drive's data capacity is equal to the number of drive members multiplied by the smallest logical drive member's capacity.
Chapter 6: Technology Background RAID 1 – Mirror When a logical drive is mirrored, identical data is written to a pair of disk drives, while reads are performed in parallel. The reads are performed using elevator seek and load balancing techniques where the workload is distributed in the most efficient manner. Whichever drive is not busy and is positioned closer to the data will be accessed first. With RAID 1, if one disk drive fails or has errors, the other mirrored disk drive continues to function.
WebPAM User Manual RAID 5 – Block Striping with Distributed Parity RAID 5 organizes data across the disk drives of the logical drive, and stores parity information on to a disk drive dedicated to this purpose. This organization allows increased performance by accessing multiple disk drives simultaneously for each operation, as well as fault tolerance by providing parity data.
Chapter 6: Technology Background RAID 10 – Mirror / Stripe Mirror/Stripe combines both of the RAID 0 and RAID 1 logical drive types. It can increase performance by reading and writing data in parallel while protecting data with duplication. At least four disk drives are needed for RAID 10 to be installed. With a four-disk-drive logical drive, one drive pair is mirrored together then striped over a second drive pair. Data Stripe Data Mirror Disk Drives Figure 4.
WebPAM User Manual JBOD – Single Drive Just a Bunch of Disks (JBOD) arranges individual physical drives on the FastTrak controller the same as if they were attached to the PC’s motherboard controller. The advantage is that a FastTrak Controller can accommodate up to four physical drives, more than most PC motherboards. JBOD offers none of the performance or security advantages of a RAID logical drive. Any number of physical drives on the FastTrak Controller can be designated as JBOD.
Chapter 6: Technology Background Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your logical drive. The following discussion summarizes some advantages, disadvantages and applications for each choice.
WebPAM User Manual RAID 5 Advantages Disadvantages High Read data transaction rate Disk failure has a medium impact on throughput Medium Write data transaction rate Good aggregate transfer rate Recommended Applications for RAID 5 • File and Application servers • Intranet servers • WWW, E-mail, and News servers • Most versatile RAID level RAID 10 Advantages Disadvantages Implemented as a mirrored logical drive Very high disk overhead - uses only whose segments are RAID 0 logical 50% of total c
Chapter 6: Technology Background Choosing Stripe Block Size The stripe block size value can be set to 32 KB, 64 KB and 128 KB. 64 KB is the default. This selection will directly affect performance. There are two issues to consider when selecting the stripe block size. • Choose a stripe block size equal to or smaller than the smallest cache buffer found on any disk drive in your logical drive.
WebPAM User Manual Hot Spare Drive(s) A hot spare is a disk drive that is connected to the logical drive system but is not assigned as a member of the logical drive. In the event of the failure of a drive within a functioning fault tolerant logical drive, the hot spare is activated as a member of the logical drive to replace a drive that has failed. FastTrak will replace a failing disk drive in a logical drive with an unassigned drive, if one is available.
Chapter 6: Technology Background Cache Settings There is a data cache on the FastTrak controller and another one on each physical disk drive. A cache holds data in volatile memory during RAID management and data transfer activity. The right combination of cache settings for your needs can improve FastTrak’s efficiency and performance. Physical Drive Write Cache – Activates the write cache on the disk drive. Write Back Cache – Activates write-back feature of FastTrak’s controller cache.
WebPAM User Manual The Expansion feature applies only to RAID 0 and RAID 5 arrays. You can add physical drives as described in the table below.
Chapter 6: Technology Background See the chart below. Current LD Size Maximum LD Expansion Size Sector Size 8 to 16 TB 16 TB 4096 bytes 4 to 8 TB 8 TB 2048 bytes 2 to 4 TB 4 TB 1024 bytes 0 to 2 TB 2 TB 512 bytes You can direct WebPAM to expand a logical drive beyond the maximum expansion size. However, when expansion is finished, your logical drive will be the maximum size listed in the table. If you require a logical drive larger than the maximum expansion size: 1.

Appendix A: Frequently Asked Questions I tried to log into WebPAM but my browser showed the message “cannot be displayed.” What is the problem? The browser decided prematurely that WebPAM was not responding. Click the Refresh button. This action usually brings up the login screen. I can access the Host PC over my company’s intranet. But I can’t access it from an outside Internet connection.
WebPAM User Manual Can I use my existing WebPAM setup to monitor a Promise subsystem product also? No. Promise subsystem products, such as UltraTrak and VTrak, have a more advanced version of WebPAM tailored to their designs. Why do the Rebuild, Synchronize, Expand and Migrate operations take so long compared to moving data? When data is moved, the operation consists of reading, writing and checking one or more files.
Appendix B: Partition and Format In order for your operating system to recognize and work with the disk drives attached to your FastTrak SX Series RAID Controller card, the drives must be partitioned and formatted.
