Page 71: Terminology Used In This Chapter
Note: Although you can use both SAS and SATA disk drives in the same SAS domain (see page 77), Adaptec recommends that you not combine SAS and SATA disk drives within the same array or logical drive. The difference in performance between the two types of disk drives may adversely affect the performance of the array. -
Page 72: How Do Sas Devices Communicate
Appendix A: Introduction to Serial Attached SCSI (SAS) How Do SAS Devices Communicate? SAS devices communicate with each other through links. A link is a physical connection between two phys. As shown below, SAS devices contain ports (see page 73), ports contain phys (see below), and each phy contains one transmitter and one receiver—one transceiver. -
Page 73: What's A Sas Port
Appendix A: Introduction to Serial Attached SCSI (SAS) What’s a SAS Port? Note: Because the physical link between SAS devices is from phy to phy, rather than port to port, a “port” is more of a virtual concept, different from what is normally considered a port on other types of RAID controllers and storage devices. -
Page 74: What's A Sas Connector
Appendix A: Introduction to Serial Attached SCSI (SAS) What’s a SAS Connector? A SAS connector is the physical plug or receptacle that you see on a SAS device. It supports the power and signal line cable. It’s what you plug a SAS cable into, or the end of the SAS cable that’s being plugged in. -
Page 75: What Do Sas Cables Look Like
Appendix A: Introduction to Serial Attached SCSI (SAS) What do SAS Cables Look Like? Internal SAS cables are narrower than internal parallel SCSI cables. The connectors vary in size depending on the number of links they support, from single link connectors to 4-wide (or larger) connectors. Internal fan-out cables (shown below) let you attach four disk drives to a single 4-wide connector. -
Page 76: What Are The Sas Connection Options
12 SAS or SATA disk drives. Some backplanes support daisy-chain expansion to other backplanes. For example, you can daisy-chain (connect one to the next) up to nine Adaptec S50 enclosures to a single SAS card in a host system. -
Page 77: Sas Expander Connections
Appendix A: Introduction to Serial Attached SCSI (SAS) SAS Expander Connections A SAS expander device literally expands the number of end devices that you can connect together. Expander devices, typically embedded into a system backplane (see page 76), support large configurations of SAS end devices, including SAS cards and SAS and SATA disk drives. -
Page 78: How Is Sas Different From Parallel Scsi
Appendix A: Introduction to Serial Attached SCSI (SAS) How is SAS Different from Parallel SCSI? In summary, although SAS and parallel SCSI both use the SCSI command set, how they move data from one place to another is very different. To support point-to-point serial data transport, SAS introduces new types of connectors, cables, connection options, and terminology. - Page 79 RAID levels also vary by the number of disk drives they support. This appendix describes the RAID levels supported by your Adaptec RAID controller, and provides a basic overview of each to help you select the best level of protection for your data storage.
-
Page 80: Understanding Drive Segments
Appendix B: Understanding RAID Understanding Drive Segments A drive segment is a disk drive or portion of a disk drive that is used to create an array. A disk drive can include both RAID segments (segments that are part of an array) and available segments. Each segment can be part of only one logical device at a time. -
Page 81: Raid 1 Arrays
Appendix B: Understanding RAID RAID 1 Arrays A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the other (the same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays provide improved performance, with twice the read rate and an equal write rate of single disks. -
Page 82: Raid 1 Enhanced Arrays
Appendix B: Understanding RAID RAID 1 Enhanced Arrays Note: RAID 1E is an upgrade feature; if the RAID 1E feature is locked, Adding Enhanced Features on page 20 for information on purchasing a feature key. A RAID 1 Enhanced (RAID 1E) array is similar to a RAID 1 array except that data is both mirrored and striped, and more disk drives can be included. -
Page 83: Raid 10 Arrays
RAID 10 Arrays A RAID 10 array is built from two or more equal-sized RAID 1 arrays. Adaptec RAID controllers support a maximum number of 48 disk drives in a RAID 10 array. Data in a RAID 10 array is both striped and mirrored. Mirroring provides data protection, and striping improves performance. -
Page 84: Raid 5 Arrays
Appendix B: Understanding RAID RAID 5 Arrays A RAID 5 array is built from a minimum of three and a maximum of sixteen disk drives, and uses data striping and parity (see below) data to provide redundancy. Parity data provides data protection, and striping improves performance. -
Page 85: Raid 5Ee Arrays
Appendix B: Understanding RAID RAID 5EE Arrays Note: RAID 5EE is an upgrade feature; if the RAID 5EE feature is locked, see Adding Enhanced Features on page 20 for information on purchasing a feature key. A RAID 5EE array is similar to a RAID 5 array except that it includes a distributed spare drive (see below) and must be built from a minimum of four disk drives. -
Page 86: Raid 50 Arrays
RAID 5 arrays. (For more information, see RAID 5 Arrays on page 84.) Note: Because the Adaptec 2420SA RAID controller can’t support more than four disk drives, it can’t support RAID 50 arrays. The parity data provides data protection, and striping improves performance. -
Page 87: Raid 6 Arrays
Appendix B: Understanding RAID RAID 6 Arrays Note: RAID 6 is an upgrade feature; if the RAID 6 feature is locked, see Adding Enhanced Features on page 20 for information on purchasing a feature key. A RAID 6 array is similar to a RAID 5 array because it uses data striping and parity data to provide redundancy. -
Page 88: Raid 60 Arrays
RAID 6 arrays. Note: Because the Adaptec 2420SA RAID controller can’t support more than four disk drives, it can’t support RAID 60 arrays. Two sets of parity data provide enhanced data protection, and striping improves performance. -
Page 89: Selecting The Best Raid Level
RAID 60 Because it supports a maximum of four disk drives, the Adaptec 2420SA RAID controller can’t support RAID 50 or RAID 60. Disk drive usage, read performance, and write performance depend on the number of drives in the logical drive.

Page 105: Creating The Script File Manually
Appendix D: Using the ACU for DOS Creating the Script File Manually Script files contain blocks: Array definition block keywords (see below) Optional—ACU error codes (see page 112) The syntax rules are: Each keyword must start its own line. Syntax is not case sensitive. Entering Comments in the Script File To enter a comment in the script file, start with a pound character ( You can start anywhere on a line. - Page 106 Appendix D: Using the ACU for DOS Keyword Required? Description Size Specifies the size of the array. Default is Maximum. See page 109. StripeSize Specifies the size of contiguous I/O, in bytes. Default is 256. See page 109. Type Indicates the type of array to create. No default See page 109.
- Page 107 Appendix D: Using the ACU for DOS End Keyword is a required keyword, indicating the end of the block. HotspareDrives Keyword is an optional keyword, specifying the hot spares to HotspareDrives assign to the array. The syntax for listing hot spares is the same as the Drives Keyword on page 106.

- Page 109 Appendix D: Using the ACU for DOS Size Keyword keyword specifies the size of the array. Specify (the Size Maximum default) to create an array using the maximum available space, based on the array type and drives selected. Otherwise, specify the size as an integer or a decimal number, followed by the unit keyword MB (megabytes), GB (gigabytes), or TB (terabytes).

Page 111: Channel Definition Block Keywords-Scsi Only
Normally, the SCSI controller is assigned SCSI ID 7 on each of its channels. You can specify any ID value between 0 and 7. Caution: Do not change the SCSI ID of the controller unless directed to do so by Adaptec Technical Support. For example: ControllerID=7 End Keyword is a required keyword, indicating the end of the block. -
Page 112: Acu Error Codes
Appendix D: Using the ACU for DOS ACU Error Codes When the ACU detects an error, it reports the error and exits immediately. If a log file is specified, the ACU writes the error code to the log file. Otherwise, it displays the error code on the screen. The possible error messages returned by the ACU are listed in this table. -
