VessRAID 1000i Series Product Manual RAID 0 – Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple physical 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. Figure 1.
Chapter 8: Technology Background RAID 1 – Mirror When a logical drive is mirrored, identical data is written to a pair of physical 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.
VessRAID 1000i Series Product 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 physical drives. It also offers overall increased read/ write performance plus the flexibility of using an odd number of physical drives. With RAID 1E, each data stripe is mirrored onto two physical drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance. Figure 3.
Chapter 8: Technology Background 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. It works well for file, database, application and web servers. Figure 4.
VessRAID 1000i Series Product 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 logical drive can continue to accept I/O requests when any two physical drives fail. Figure 5. RAID 6 stripes all drives with data and dual parity Double Distributed (Wide-space Q+Q) Parity Data Blocks Physical Drives Hence, a RAID 6 logical drive with (7) 100 GB physical drives will have a capacity of 500 GB.
Chapter 8: Technology Background RAID 10 – Mirror / Stripe Mirror + Stripe combines both of the RAID 1 and RAID 0 logical drive types. RAID 10 can increase performance by reading and writing data in parallel— striping—while protecting data by duplicating it—mirroring. Promise implements RAID 10 by creating a data stripe over one pair of disk drives, then mirroring the stripe over a second pair of disk drives. Some applications refer to this method as RAID 0+1. Figure 6.
VessRAID 1000i Series Product Manual RAID 50 – Striping of Distributed Parity RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across physical drives 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. Figure 7.
Chapter 8: Technology Background RAID 50 Axles When you create a RAID 50, you must specify the number of axles. An axle refers to a single RAID 5 logical drive that is striped with other RAID 5 logical drives to make RAID 50. An axle can have from 3 to 16 physical drives, depending on the number of physical drives in the logical drive. The chart below shows RAID 50 logical drives with 6 to 16 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle.
VessRAID 1000i Series Product 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. Figure 8. RAID 60 is a combination of RAID 6 and RAID 0 Double Distributed Parity Axle 1 Data Stripes Axle 2 Disk Drives Figure 9.
Chapter 8: Technology Background RAID 60 Axles When you create a RAID 60, you must specify the number of axles. An axle refers to a single RAID 6 logical drive that is striped with other RAID 6 logical drives to make RAID 60. An axle can have from 4 to 16 physical drives, depending on the number of physical drives in the logical drive. The chart below shows RAID 60 logical drives with 8 to 20 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle.
VessRAID 1000i Series Product Manual Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your VessRAID disk array. The following discussion summarizes some advantages, disadvantages, and applications for each choice.
Chapter 8: Technology Background RAID 1E Advantages Disadvantages 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 file server RAID 5 Advantages Disadvantages High Read data transaction rate Medium Write data transaction rate Good a

Chapter 8: Technology Background 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 choose Stripe Size directly when you use the Advanced function to create a disk array.
VessRAID 1000i Series Product Manual • Linux operating systems with the 2.6 kernel support 64-bit LBA. For these OSes, always choose the default 512 B sector size. 2 TB Limitation If your Host PC runs Windows 2000 or Windows XP (32-bit), and you want to create logical drives larger than 2TB, you must choose a sector size larger than 512 B when you create the logical drive. The table below correlates sector size with logical drive capacity.
Chapter 8: Technology Background Read Cache Policy • Read Cache – The read cache is enabled. • Read Ahead – The read cache and the read-ahead feature are enabled. Read-ahead anticipates the next read and performs it before the request is made. Can increase read performance. • No Cache – The read cache is disabled. Write Cache Policy • Write Back – Data is written first to the cache, then to the logical drive. Better performance.
VessRAID 1000i Series Product Manual The write policy automatically changes to Write Thru. When the battery comes back online, the write policy automatically changes back to Write Back. To enable the Adaptive Writeback Cache option, see “Making Controller Settings” on page 96 (WebPAM PROe) or page 147 (CLU). Also see “Replacing the Cache Battery” on page 240. Capacity Coercion This feature is designed for fault-tolerant logical drives (RAID 1, 1E, 5, 10, 50, and 60).
Chapter 8: Technology Background drives. See “Initializing a Logical Drive” on page 129 (WebPAM PROe) or page 173 (CLU). Caution When you initialize a logical drive, all the data on the logical drive will be lost. Backup any important data before you initialize a logical drive. 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.
VessRAID 1000i Series Product Manual 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) On VessRAID, RAID level migration is performed on the disk array but it applies to the logical drives. 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.
Chapter 8: Technology Background RAID 0 A RAID 0 source logical drive can migrate to the following target logical drives: Target Requirements RAID 0 Add physical drives. RAID 1 2 physical drives only. Only a single-drive RAID 0 can migrate to RAID 1 by adding 1 physical drive. RAID 1E 3 or more physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 5 3 physical drives minimum, 16 maximum. RAID 0 must have less than 16 physical drives.
VessRAID 1000i Series Product Manual RAID 1 A RAID 1 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E 3 or more physical drives. Add 1 or more physical drives. RAID 5 3 physical drives minimum, 16 maximum. RAID 1 must have less than 16 physical drives. Add 1 or more physical drives. RAID 10 4 physical drives minimum. Even number of physical drives. Add 2 or more physical drives.
Chapter 8: Technology Background RAID 5 A RAID 5 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 Add physical drives. 16 maximum. RAID 6 4 physical drives minimum, 16 maximum. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 4 physical drives minimum. Even number of physical drives. If existing physical drives have no unused space, add 1 or more physical drives.
VessRAID 1000i Series Product Manual RAID 10 A RAID 10 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 3 physical drives minimum, 16 maximum. RAID 10 must have less than 16 physical drives. RAID 6 4 physical drives minimum, 16 maximum. RAID 10 must have less than 16 physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 Add physical drives.
Chapter 8: Technology Background RAID 50 A RAID 50 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 16 physical drives maximum. RAID 50 must have less than 16 physical drives. RAID 6 16 physical drives maximum. RAID 50 must have less than 16 physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 Even number of physical drives. RAID 50 Add physical drives.
VessRAID 1000i Series Product Manual Important • The Target disk array may require more physical drives than the Source disk array • If the Target disk array requires an EVEN number of physical drives but the Source disk array has an ODD number, ADD a physical drive as part of the migration process • You cannot reduce the number of physical drives in your disk array, even if the Target disk array requires fewer physical drives than the Source disk array • RAID 1 (mirroring) works with two drives onl
Chapter 8: Technology Background Current LD Size Maximum LD Expansion 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 up to 2 TB 2 TB 512 bytes Sector Size At this point, you have the choice of: • Format the unpartitioned/unformatted capacity as a second logical drive • Delete the existing disk array and create a new one in the desired size Delete and Recreate If you require a logical drive larger than the maximum expansion size: 1.
VessRAID 1000i Series Product Manual 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” on page 58 (WebPAM PROe) or page 166 (CLU).
Chapter 8: Technology Background Transition The Transition feature enables you to specify “permanent” spare drives for your VessRAID 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. Transition happens automatically when the following sequence of events takes place: • You create a revertible spare drive.
VessRAID 1000i Series Product Manual Example Following is an example to explain the Transition function. In the example above, there is a four-drive RAID 5 disk array and a global spare drive. Physical drives 1, 2, 3, and 4 belong to the disk array. Physical drive 5 remains unconfigured. Physical drive 6 is a revertible spare drive. If a physical drive fails in a disk array and there is a spare drive of adequate capacity available, the controller automatically rebuilds the array using the spare drive.
Chapter 8: Technology Background 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 3 with a new one of the same or greater capacity.

VessRAID 1000i Series Product Manual Critical & Offline Disk Arrays A fault-tolerant disk array—RAID 1, 1E, 5, 10, and 50—goes critical when a disk drive is removed or fails. A RAID 6 or 60 disk array—goes degraded when a disk drive is removed or fails and critical when two disk drives are removed of fail. Due to the fault tolerance of the disk array, the data is still available and online.
Chapter 9: Troubleshooting • The Disk Status LED changes from green to red. Figure 14.VessRAID disk drive carrier LEDs Disk Status Power/Activity • The audible alarm repeatedly sounds two short beeps. See page 277. • WebPAM PROe reports the condition. See page 284. Also see “Physical Drive Problems” on page 306.
VessRAID 1000i Series Product Manual To enable Automatic Rebuild, see “Making Background Activity Settings” on page 56 (WebPAM PROe) or page 184 (CLU). To set Hot Spare Policy, see “Making Spare Drive Settings” on page 135 (WebPAM PROe) or page 170 (CLU). Important If your replacement disk drive was formerly part of a different disk array or logical drive, you must clear the configuration data on the replacement drive before you use it. See page 108 (WebPAM PROe) or page 156 (CLU).
Chapter 9: Troubleshooting Incomplete Array An incomplete array can result from any of the following conditions: • The NVRAM watermark for the RAID level migration currently in progress is missing or cannot be found • A physical drive goes missing during transport See “Physical Drive Failed” on page 306 for more information.
VessRAID 1000i Series Product Manual Physical Drive Problems Physical Drive Offline Check the drive for: • PFA Condition – Caused by a bad block or sector. See “Clearing Stale and PFA Conditions” on page 108 (WebPAM PROe) or page 156 (CLU). • Stale Configuration – Caused by obsolete array information on the physical drive. Identify the disk array to which the physical drive belongs. Then delete the disk array. See “Deleting a Disk Array” on page 119 (WebPAM PROe) or page 162 (CLU).
Chapter 9: Troubleshooting You can set the VessRAID to migrate disk arrays under Non-Volatile Random Access Memory (NVRAM), a much faster process because it writes data to the memory in the controller. However, if a physical drive or the controller fails during migration, the logical drives will go offline and you will lose data. See “Incomplete Array” on page 305. Because the setting for migration under NVRAM requires special access, most users will not encounter this condition.
VessRAID 1000i Series Product Manual Enclosure Problems WebPAM PROe displays yellow !s components that need attention. red Xs in Tree View to identify When a yellow ! appears over a Subsystem in Tree View, click the Enclosure icon. The Enclosure screen will display (below). Figure 16.Enclosure information in Management View In this example, one of the RAID Controller fans has failed. The Enclosure Diagram displays color and motion changes to identify the failed fan.
Chapter 9: Troubleshooting Enclosure Overheat Overheating is a potentially serious condition because the excessively high temperatures can lead to disk drive failure and controller malfunction. Overheating usually results from: • Fan failure • Poor air circulation around the enclosure Fan Failure On VessRAID, there are two kinds of fans: • Power supply fan • RAID Controller fan If a power supply fan fails, you must replace the power supply. If a RAID Controller fan fails, you can replace it onsite.
VessRAID 1000i Series Product Manual Power Supply VessRAID 1800i Series VessRAID 1800i Series has two power supplies. The advantage of two power supplies is that, should one fail, the other will continue powering the subsystem. The power supplies are hotswappable. VessRAID 1700i Series VessRAID 1700i Series has only one power supply and it is not replaceable onsite. If you need to replace the power supply, contact Technical Support and make arrangements to return the subsystem to Promise for service.
Chapter 9: Troubleshooting Connection Problems When you install your Promise product following the instructions in the Quick Start Guide and this Product Manual, you should have little trouble getting your equipment to work the first time. But connection problems can arise that are not the User's or Installer's fault. Every conceivable problem cannot be covered in the documentation but some guidelines could be helpful. Connection problems cause a majority of failures in almost any electrical system.
VessRAID 1000i Series Product Manual Network Connections Each controller has one Ethernet RJ45 connector on the back of the enclosure for the Management port and four RJ45 connectors for the iSCSI ports. The VessRAID becomes a node on your network like any other PC or server. VessRAID supports DHCP. If there is a DHCP server on your network, do not assign an IP address manually without consulting your network administrator.

VessRAID 1000i Series Product Manual Unsaved Data in the Controller Cache The Dirty Cache LED informs you that there is data in the cache that has not been saved to non-volatile memory. Such data is sometimes called “dirty,” not to suggest it is corrupted in some way but because it has not been saved to a disk drive. Figure 20.Dirty Cache LED Dirty Cache LED If there is unsaved data in the controller’s cache, the Dirty Cache LED shines amber. During this time, do NOT power down the VessRAID.
Chapter 10: Support • Frequently Asked Questions (below) • Contacting Technical Support (page 319) • Limited Warranty (page 323) • Returning the Product For Repair (page 325) Frequently Asked Questions What kind of disk drives can I use with VessRAID? VessRAID supports 3.0 GB/s Serial ATA disk drives and 3.0 Gb/s SAS drives. VessRAID does not support Parallel ATA (PATA) disk drives.
VessRAID 1000i Series Product Manual WebPAM PROe connection was working OK. But later on, it timed out. What do I do now? The network condition can time-out for several reasons. When an open connection has no action for a specific amount of time (the Administrator can change it), the connection times-out automatically for security reasons. When you attempt to use WebPAM, it returns to the login screen. Enter your user name and password and click Login, and WebPAM will establish a new connection.
Chapter 10: Support How can I be sure everything is working OK on the VessRAID? Locally: The VessRAID enclosure has LEDs on the front to monitor the status of power, field replaceable units (FRUs) and logical drives. When these are green, VessRAID is functioning normally. Remotely: Check the Tree Icons in WebPAM. If there are no yellow or red warning icons displayed, VessRAID is functioning normally.
