User Manual BC4000 Series RAID Controllers 02/13/06 Sect io n 1: I ntro duc tio n This manual describes the installation and operation of Broadcom’s RAIDCore™ BC4000 Series RAID controllers, which includes HT-1000 controllers, as well as the use of RAIDCore XelCore™ RAID management software.
Page 16: Section 2: Overview Of Raid Concepts
BC4000 Series RAID Controllers User Manual 02/13/06 S ect ion 2: Over v iew of R A ID Co ncep ts NDERSTANDING RRAYS Disk arrays are several disks that are grouped together in various organizations to improve either the performance or the reliability of a computer’s storage system. Because some array types enhance performance while others improve reliability, and because some array types enhance both, it is important to consider your needs when planning an array configuration.
Page 17: Expanding Disk Capacity Online
User Manual BC4000 Series RAID Controllers 02/13/06 • RAID5: RAID5, also known as a stripe with parity, stripes data as well as parity across all drives in the array. Parity information is interspersed across the drive array. In the event of a failure, the controller can restore the lost data of the failed drive from the other surviving drives.
Page 18: Performance Considerations
BC4000 Series RAID Controllers User Manual 02/13/06 ERFORMANCE ONSIDERATIONS One of the main advantages of using RAID is increased performance. With RAID, performance is based on four elements: the number and organization of disks in an array, the caching attributes being used for the array, the application workload, and the PCI bus speed.
Page 19: Flexibility And Expansion Considerations
User Manual BC4000 Series RAID Controllers 02/13/06 LEXIBILITY AND XPANSION ONSIDERATIONS Before configuring an array, consider the following points to enhance the flexibility of your RAID system. ULTIPLE YPES Most RAID controllers do not allow you to change a chosen array type, create more than one type of array for each controller, or to create more than one array per physical disk.

Follow the instructions provided below, depending on your operating system. To transfer the drivers to a floppy disk (Windows): You can use any computer that is running Windows and has both a CD-ROM drive and a floppy disk drive.
Page 37: New Installation Of Windows 2000, Xp, Or 2003
User Manual BC4000 Series RAID Controllers 02/13/06 New Installation of Windows 2000, XP, or 2003 You can install a new operating system at the same time you install the drivers for the controller(s). The Windows 2003 procedure for installing more than one controller is similar to installing only one, except that the Found New Hardware Wizard runs two additional times for each additional controller.
Page 38: Existing Installation Of Windows 2000, Xp, Or 2003
BC4000 Series RAID Controllers User Manual 02/13/06 Existing Installation of Windows 2000, XP, or 2003 Installing the RAIDCore BC4000 Series controller involves the installation of device drivers for the controller and the RAIDCore Configuration Device. To install the BC4000 Series RAID controller device driver: Install the controller and hard disk drives.
Page 39 User Manual BC4000 Series RAID Controllers 02/13/06 11. Click Finish. 12. If you are installing more than one controller, the operating system discovers the next controller and repeats this process. When all the controller drivers are installed, the system then discovers the RAIDCore configuration device. To install the configuration device driver: In Found New Hardware Wizard, click Install from a List or Specific Location, and then click Next.

To copy an array from bcadm, see “Copying Arrays: bcadm --create-copy” on page 136. NDERSTANDING RRAY AND TATES The controller uses states to report the status of arrays and disks. To ensure the health of your data, it is important to understand what each array and disk state mean as well as what causes them to change.
Page 59: Disk States
User Manual BC4000 Series RAID Controllers 02/13/06 More than one array can be created using the same set of disks. If you disconnect a disk that belongs to more than one array, only the arrays that try to access the disk and receive I/O errors report the failure. For example: you have two arrays, both RAID5 sets, and both use disk 4.

Page 61: Working With Spares
User Manual BC4000 Series RAID Controllers 02/13/06 ORKING WITH PARES BOUT PARING PTIONS The BC4000 Series RAID controller supports three sparing options. Distributed A patent-pending sparing option that consists of reserved space on each disk in an array Dedicated A spare disk assigned to a specific, redundant array Global A spare disk that is shared by multiple arrays Spares are restored in the following order:...
Page 62 BC4000 Series RAID Controllers User Manual 02/13/06 Notes: • If there is insufficient unused space on the disks in an array, you cannot add a distributed spare without adding an additional disk and transforming to an array with distributed sparing enabled. The distributed spare option uses the equivalent storage of one of the disks in the array.
Page 63: Using Dedicated Sparing
User Manual BC4000 Series RAID Controllers 02/13/06 SING EDICATED PARING A dedicated spare is a disk that you assign as an alternate disk for a specific array. Should a disk fail in that array, the alternate disk is used to replace the failed disk and the array is rebuilt. A dedicated spare can be assigned to any redundant array type, and up to four spares can be assigned to an array.

User Manual BC4000 Series RAID Controllers 02/13/06 BIOS NITIALIZING ISKS FROM THE Before using new disks, they must be initialized, and at least the boot array must be created using RAIDCore BIOS Array Configuration utility. Initialization writes the RAIDCore configuration information to disk. This process is the same whether you have one controller or multiple controllers.
Page 66: Creating Arrays From The Bios
BC4000 Series RAID Controllers User Manual 02/13/06 Press Enter to initialize the selected disks. Press the C key to continue with initialization. Initialization takes 10–15 seconds per disk. A status indicator shows which disk is being initialized. When the initialization is complete, the status indicator goes away and a complete rescan of all channels is done automatically.
Page 67 User Manual BC4000 Series RAID Controllers 02/13/06 To select an array size, do one of the following. Note: Use the Page Up and Page Down keys to increase or decrease the array size in large increments, and use the Up Arrow and Down Arrow keys to increase or decrease the array size in small increments.
Page 68: Deleting Arrays From The Bios
BC4000 Series RAID Controllers User Manual 02/13/06 BIOS ELETING RRAYS FROM THE This option allows you to delete arrays. Caution! Deleting an array permanently destroys all data that was on the array. This action cannot be undone, and all data will be lost. To Delete an Array: Highlight Delete Array(s) from the Main menu and press Enter.
Page 69: Swapping Arrays From The Bios
User Manual BC4000 Series RAID Controllers 02/13/06 BIOS WAPPING RRAYS FROM THE Using the Swap Two Arrays option, you can reorder arrays. Notes: • If you create more than one array, you can install the operating system to any of them. However, a small amount of boot information is always written to a disk in the first array on your array list regardless of which array you install the operating system on.
Page 70: Hiding Or Unhiding Arrays From The Bios
BC4000 Series RAID Controllers User Manual 02/13/06 BIOS IDING OR NHIDING RRAYS FROM THE The Hide/Un-Hide array option allows you to hide or unhide an array or arrays from the operating system. If an array is hidden, it will not be visible through INT13 or to the operating system when booted. This is a useful feature for hiding hot backups of the system.
