Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.2 Choosing a R.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 0 –Stripe When a disk array is striped, the read and write blocks of data are interleaved between the sectors of multiple drives. Performance is increased, since the workload is balanced between drives or “members” that form the disk array. Identical disk drives are recommended for performance as well as data storage efficiency.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 1 –Mirror When a disk array is mirrored, identical data is written to a pair of 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.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 1E –Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two disk drives. It also offers overall increased read/write performance plus the flexibility of using an odd number of disk drives. With RAID 1E, each data stripe is mirrored onto two disk drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 5 –Block and Parity Stripe RAID 5 organizes block data and parity data across the physical drives. Generally, RAID Level 5 tends to exhibit lower random write performance due to the heavy workload of parity recalculation for each I/O. RAID 5 is generally considered to be the most versatile RAID level Fig 7.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 6 –Block and Double Parity Stripe RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A RAID 6 disk array can continue to accept I/O requests when any two physical drives fail. The total capacity of a RAID 6 disk array is the smallest physical drive times the number of physical drives, minus two.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 10 –Mirror + Stripe Mirroring/striping combines both of the previous RAID 1 and RAID 0 disk array types. RAID 10 is similar though not identical to RAID 0+1. RAID 10 can increase performance by reading and writing data in parallel while protecting data with duplication. At least four drives are needed for RAID 10 to be installed. With four disk drives, the drive pairs are striped together with one pair mirroring the first pair.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 50 –Striping of Distributed Parity RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses distributed parity as in RAID 5. RAID 50 provides data reliability, good overall performance and supports larger volume sizes. Distributed Parity Fig 7.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual The chart below shows RAID 50 arrays with 6 to 16 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle. RAID 50 Array No.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 60 –Striping of Double Parity RAID 60 combines both RAID 6 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses double distributed parity as in RAID 6. RAID 60 provides data reliability, good overall performance and supports larger volume sizes. Fig 7.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual The chart below shows RAID 60 arrays with 8 to 20 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle. RAID 60 Array No.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.2 Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your Galaxy3G disk array. The following discussion summarizes some advantages, disadvantages, and applications for each choice.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual Implemented as a mirrored disk array whose segments are RAID 0 disk arrays High I/O rates are achieved thanks to multiple stripe segments Can use an odd number of disks Very high disk overhead - uses only 50% of total capacity Recommended Applications for RAID 1E • Imaging applications • Database servers • General fileserver RAID 5 Advantages High Read data transaction rate Medium Write data transaction rate Good aggregate transfer
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual Implemented as a mirrored disk array whose segments are RAID 0 disk arrays High I/O rates are achieved thanks to multiple stripe segments Very high disk overhead - uses only 50% of total capacity Recommended Applications for RAID 10 • Video and Imaging applications • Database servers • General fileserver 227 Section 7 Technology Background
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 50 Advantages High Read data transaction rate Medium Write data transaction rate Good aggregate transfer rate High reliability Supports large volume sizes Disadvantages Higher disk overhead than RAID 5 Recommended Applications for RAID 50 • File and Application servers • Transaction processing • Office application with many users accessing small files RAID 60 Advantages High Read data transaction rate Medium Write data trans
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.3 Choosing Stripe Size Stripe Size, also called “Stripe Block Size”, refers to the size of the data blocks written to, and read from, the physical drives. Stripe Size is specified when you create a disk array. In order to change the Stripe Size of an existing disk array, you must delete the disk array and create a new one. You can select Stripe Size directly when you use the Advanced function to create a disk array.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.4 Choosing Sector Size A sector is the smallest addressable area on a physical disk drive. Sector Size refers to the size of sector measured by the number of bytes of data it can hold. The most common sector size is 512 bytes (512 B). A smaller sector size results in a more efficient use of a disk drive’s capacity. 512 B is the default sector size for logical drives in the Galaxy3G.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.5 Cache Policy As it is used with Galaxy3G, the term cache refers to any of several kinds of high-speed, volatile memory that hold data moving from your computer to the physical drives or vice-versa. Cache is important because it can read and write data much faster than a physical drive. There are read caches, which hold data as it is read from a physical drive; and write caches, which hold data as it is written to a physical drive.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.6 LUN Affinity Galaxy3G Fibre Channel subsystems with two controllers include a LUN Affinity feature. Normally, either controller can access all logical drives. LUN Affinity enables you to specify which controller can access each logical drive. Use this feature to balance the load of your logical drives between the two controllers.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.7 Capacity Coercion This feature is designed for fault-tolerant logical drives (RAID 1, 1E, 5, 10, 50, and 60). It is generally recommended to use physical drives of the same size in your disk arrays. When this is not possible, physical drives of different sizes will work but the system must adjust for the size differences by reducing or coercing the capacity of the larger drives to match the smaller ones.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.8 Initialization Initialization is done to logical drives after they are created from a disk array. Initialization sets all data bits in the logical drive to zero. The action is useful because there may be residual data on the logical drives left behind from earlier configurations. For this reason, Initialization is recommended for all new logical drives. See “Initializing a Logical Drive” in chapter 4.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.9 Hot Spare Drive(s) A hot spare is a disk drive that is connected to the disk array system but is not assigned as a member of the disk array. In the event of the failure of a drive within a functioning fault tolerant disk array, the hot spare is activated as a member of the disk array to replace a drive that has failed. Galaxy3G will replace a failing disk drive in a disk array with an unassigned drive, if one is available.

Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.10 Partition and Format the Logical Drive Like any other type of fixed disk media in your system, a RAID logical drive must also be partitioned and formatted before use. Use the same method of partitioning and formatting on a logical drive as you would any other fixed disk. Depending on the operating system you use, there may or may not be various capacity limitations applicable for the different types of partitions.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.11 RAID Level Migration To migrate a disk array is to do one or both: • Change its RAID level • Increase the number of disk drives (sometimes called Expansion) Migration takes place on an existing Functional disk array without disturbing the existing data. While the disk array is migrating, you can access the data as before. When migration is complete, your disk array will have a different RAID level and/or a larger capacity.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual RAID 1E RAID 1 RAID 0 RAID 0 • RAID 50 • RAID 10 • RAID 5 • RAID 0 • RAID 50 • RAID 10 • RAID 5 • RAID 1E • RAID 0 • RAID 50 • • RAID 10 • • RAID 5 RAID 1E • • • • • • • • • RAID 1 • • * Decreases the existing redundancy Important 239 • The Target disk array may require more disk drives than the Source disk array.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 240 Section 7 Technology Background
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual Ranges of Disk Array Expansion The Windows 2000 and Windows XP (32-bit) operating systems support a 10-byte LBA format. As a result, these OSes can only recognize 4 billion addresses. If you create a logical drive using the default 512 B sector size, the logical drive will be limited to 2 TB of data, even if there is more space available on your disk drives.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.12 Media Patrol Media Patrol is a routine maintenance procedure that checks the magnetic media on each disk drive. Media Patrol checks all physical drives assigned to disk arrays. Media Patrol does not check unconfigured drives. Media Patrol will also check spare drives, if those drives have Media Patrol enabled. Media Patrol for spare drives is enabled by default. You can disable it in Galaxy3G’s Command Line Interface (CLI).
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.13 Predictive Data Migration (PDM) Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare disk drive, similar to Rebuilding a Logical Drive. But unlike Rebuilding, PDM constantly monitors your disk drives and automatically copies your data to a spare disk drive before the disk drive fails and your Logical Drive goes Critical. See “Running PDM”.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual 7.14 Transition The Transition feature enables you to specify “permanent” spare drives for your Galaxy3G subsystem. Transition is the process of replacing a revertible spare drive that is currently part of a disk array with an unconfigured physical drive or a non-revertible spare. The revertible spare drive returns to its original status.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual There is no spare drive at this moment. Even if physical drive 5 is of adequate capacity, it has not been designated as a spare, therefore the controller cannot use it as a spare. Automatic Transition At this juncture, you would replace the failed drive in slot 4 with a new one of the same or greater capacity.

Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual Power Supplies Galaxy3Gs are equipped with redundant power supplies. The advantage of dual power supplies is that, should one fail, the other will continue powering the subsystem until the faulty one can be replaced. Galaxy3G is capable of operating on a single power supply. As a result, if one power supply fails you must watch the front panel LEDs or the Galaxy Array Manager in order to become aware of the condition.
Galaxy G3G12 / G3G16 - Installation and Hardware Reference Manual Battery Galaxy3G uses a battery as backup power for the cache. Should a power failure occur, the battery enables the cache to hold data up to 72 hours. The battery recharges during normal Galaxy3G operation. In most cases, installing a replacement battery will correct a marginal or failed condition. The battery is located in the cooling unit above the controller. Remove the cooling unit for access. The battery is hot-swappable.
