Overview 1 Server Administrator Storage Management provides enhanced features for configuring the locally attached RAID and non-RAID disk storage on a system. Storage Management enables you to perform controller and enclosure functions for all supported RAID and non-RAID controllers and enclosures from a single graphical user interface (GUI) or command-line interface (CLI). The GUI is wizard-driven and includes features for novice and advanced users. The CLI is fully featured and scriptable.
drivers are also supported. For the most recent driver and firmware requirements, contact your service provider. NOTE: To download the latest storport driver, see the Microsoft Knowledge Base article KB943545 at support.microsoft.com. If you install Storage Management without the minimum required firmware and drivers, Storage Management may not be able to display the controllers or perform other functions.
• Broadcom SAS 9300-8e • Broadcom SAS 9206-16e • SAS 12 Gbps HBA • HBA 330 NOTE: Storage Management only enumerates and provides the PCI slot information for Broadcom SAS 9207-8e and SAS 9300-8e controllers. As Storage Management does not monitor these nonRAID controllers, devices connected to these controllers are not enumerated, alerts are not logged, and SNMP traps are not sent for these controllers.
Getting Started 2 Server Administrator Storage Management is designed for system administrators who implement hardware RAID solutions and understand corporate and small business storage environments. Storage Management enables you to configure the storage components attached to your system. These components include RAID and non-RAID controllers and the channels, ports, enclosures, and disks attached to them.
On A System Running Linux And Any Remote System To start a Server Administrator session on a Linux or any remote system, click the Server Administrator icon on your desktop and log in using an account with Administrator privileges. Or, open a web browser and type one of the following in the address field and press : https://:1311 where is the assigned name for the managed system and 1311 is the default port.
Health On the Properties page, click Health to view the status information for the storage components. Related links Storage Health Information/Configuration On the Properties page, click Information/Configuration to view the property information for a storage object. The Information/Configuration subtabs also have options for executing storage tasks or launching wizards. Using The Storage Management Command-Line Interface Storage Management has a fully featured command-line interface (CLI).
– Protecting Your Virtual Disk With A Hot Spare — This topic provides information on hot spares and controller-specific information. • Perform a Check Consistency — The Maintaining The Integrity Of Redundant Virtual Disks task verifies the accuracy of the redundant data on a virtual disk. • Reconfigure a Virtual Disk — To expand the capacity of a virtual disk you can add physical disks to the virtual disk. You can also change the RAID levels.
Understanding RAID concepts 3 Storage Management uses the Redundant Array of Independent Disks (RAID) technology to provide Storage Management capability. Understanding Storage Management requires an understanding of RAID concepts, as well as some familiarity with how the RAID controllers and operating system view disk space on your system.
RAID concepts RAID uses particular techniques for writing data to disks. These techniques enable RAID to provide data redundancy or better performance. These techniques include: • • • • • • • Mirroring — Duplicating data from one physical disk to another physical disk. Mirroring provides data redundancy by maintaining two copies of the same data on different physical disks. If one of the disks in the mirror fails, the system can continue to operate using the unaffected disk.
• • • • volumes, availability or fault-tolerance is achieved by maintaining redundant data. Redundant data includes mirrors (duplicate data) and parity information (reconstructing data using an algorithm). Performance — Read and write performance can be increased or decreased depending on the RAID level you choose. Some RAID levels may be more appropriate for particular applications.
When a physical disk in a concatenated or spanned volume fails, the entire volume becomes unavailable. Because the data is not redundant, it cannot be restored by rebuilding from a mirrored disk or parity information. Restoring from a backup is the only option. Because concatenated volumes do not use disk space to maintain redundant data, they are more costefficient than volumes that use mirrors or parity information.
RAID 0 characteristics: • Groups n disks as one large virtual disk with a capacity of (smallest disk size) *n disks. • Data is stored to the disks alternately. • No redundant data is stored. When a disk fails, the large virtual disk fails with no means of rebuilding the data. • Better read and write performance. RAID level 1 (mirroring) RAID 1 is the simplest form of maintaining redundant data. In RAID 1, data is mirrored or duplicated on one or more physical disks.
RAID 1 characteristics: • Groups n + n disks as one virtual disk with the capacity of n disks. The controllers currently supported by Storage Management allow the selection of two disks when creating a RAID 1. Because these disks are mirrored, the total storage capacity is equal to one disk. • Data is replicated on both the disks. • When a disk fails, the virtual disk still works. The data is read from the mirror of the failed disk. • Better read performance, but slightly slower write performance.
RAID 5 characteristics: • Groups n disks as one large virtual disk with a capacity of (n-1) disks. • Redundant information (parity) is alternately stored on all disks. • When a disk fails, the virtual disk still works, but it is operating in a degraded state. The data is reconstructed from the surviving disks. • Better read performance, but slower write performance. • Redundancy for protection of data.
RAID 6 characteristics: • Groups n disks as one large virtual disk with a capacity of (n-2) disks. • Redundant information (parity) is alternately stored on all disks. • The virtual disk remains functional with up to two disk failures. The data is reconstructed from the surviving disks. • Better read performance, but slower write performance. • Increased redundancy for protection of data. • Two disks per span are required for parity. RAID 6 is more expensive in terms of disk space.
RAID 50 characteristics: • Groups n*s disks as one large virtual disk with a capacity of s*(n-1) disks, where s is the number of spans and n is the number of disks within each span. • Redundant information (parity) is alternately stored on all disks of each RAID 5 span. • Better read performance, but slower write performance. • Requires as much parity information as standard RAID 5. • Data is striped across all spans. RAID 50 is more expensive in terms of disk space.
RAID 60 characteristics: • Groups n*s disks as one large virtual disk with a capacity of s*(n-2) disks, where s is the number of spans and n is the number of disks within each span. • Redundant information (parity) is alternately stored on all disks of each RAID 6 span. • Better read performance, but slower write performance. • Increased redundancy provides greater data protection than a RAID 50. • Requires proportionally as much parity information as RAID 6.
RAID 10 characteristics: • Groups n disks as one large virtual disk with a capacity of (n/2) disks, where n is an even integer. • Mirror images of the data are striped across sets of physical disks. This level provides redundancy through mirroring. • When a disk fails, the virtual disk still works. The data is read from the surviving mirrored disk. • Improved read performance and write performance. • Redundancy for protection of data.
Comparing RAID Level And Concatenation Performance The following table compares the performance characteristics associated with the more common RAID levels. This table provides general guidelines for choosing a RAID level. Evaluate your specific environment requirements before choosing a RAID level. NOTE: The following table does not show all supported RAID levels in Storage Management. For information on all supported RAID levels in Storage Management, see Choosing RAID Levels And Concatenation. Table 1.
RAID Level Data Availability Read Performanc e Write Performanc e Rebuild Performanc e Minimum Disks Required Suggested Uses critical information. RAID 5 Good Sequential reads: good. Transactiona l reads: Very good Fair, unless using writeback cache Fair N + 1 (N = at least two disks) Databases and other read intensive transactional uses. RAID 10 Excellent Very Good Fair Good 2N x X Data intensive environment s (large records).
No-RAID In Storage Management, a virtual disk of unknown metadata is considered a No-RAID volume. Storage Management does not support this type of virtual disks. These must either be deleted or the physical disk must be removed. Storage Management allows Delete and Rename operation on No-RAID volumes.
4 Quick Access To Storage Status And Tasks This section describes various methods to determine the status or health of the storage components on your system and how to quickly launch the available controller tasks.
Hot Spare Protection Policy The Set Hot Spare Protection Policy task allows you to set or modify the number of hot spares to be assigned to the virtual disks. After you set the number of assigned hot spares, any deviation from the protection policy threshold triggers an alert based on the severity level you set. Related links Setting Hot Spare Protection Policy Dedicated Hot Spare Protection Policy Global Hot Spare Protection Policy Storage Component Severity Component status is indicated by the severity.
The State and Progress properties display the current activity of a component. For example, an offline physical disk displays the Offline status while the Progress property displays how close to completion an operation (such as a rebuild) is.
Using Enclosure Temperature Probes Physical disk enclosures have temperature probes that warn you when the enclosure has exceeded an acceptable temperature range. Related links Setting The Temperature Probe Values Time Delay In Displaying Configuration Changes When you change the storage configuration, Storage Management quickly generates SNMP traps in response to the configuration changes. The Storage Management, Management Information Base (MIB) is also updated to reflect storage configuration changes.

Different controllers have different limitations on the stripe sizes they can support.
• • • NOTE: Storage Management does not allow you to select the Write Back policy for controllers that do not have a battery. The only exceptions are PERC S100 and PERC S300. This restriction protects a controller without a battery from the loss of data that may occur in the event of a power failure. On some controllers, the Write Back policy may be available in the controller BIOS even though it is not available in Storage Management.
controller. This feature is not dependent on the controller mode and can function as usual when the controller is running in RAID or HBA mode. Set the physical disk caching policy of all members of a virtual disk by enabling the Disk Cache Policy. When this feature is enabled, the physical disk writes data to the physical disk cache before writing it to the physical disk. Because it is faster to write data to the cache than to a disk, enabling this feature improves system performance.
operations are possible while the background initialization is running. However, other processes such as creating a virtual disk, cannot be run concurrently with background initialization. These processes cause the background initialization to cancel.

8 Support For PERC 9 Hardware Controllers The PowerEdge RAID Controller (PERC) family of enterprise-class controllers is designed for enhanced performance, increased reliability and fault tolerance, and simplified management — providing a powerful, easy-to-manage way to create a robust infrastructure and help maximize server uptime. The introduction of the PERC 9 family of hardware controllers also brings about improvements in storage solutions.
RAID Level 10 Virtual Disk Creation With Uneven Span RAID Level 10 virtual disk creation with uneven span feature is available on Storage Management User Interface (UI) and Command Line Interface (CLI). For information on Storage Management CLI, see Server Administrator Command Line Interface Guide. • Based on the minimum (and even) number of physical disks selection the firmware on the PERC 9 hardware controller recommends the preferred span layout.
Storage Management supports virtual disk creation on 4KB sector hard-disk drives connected to PERC 9 hardware controllers. NOTE: 4KB sector hard-disk drives are not supported on controllers prior to PERC 9 family of hardware controllers. If the 4KB sector hard-disk drive is connected to any hardware controller prior to PERC 9, the 4KB sector hard-disk drive is displayed as Unsupported.

RAID Controller Batteries 12 Some RAID controllers have batteries. If the controller has a battery, Storage Management displays the battery under the controller object in the tree view. If there is a power outage, the controller battery preserves data that is in the volatile cache memory (SRAM) but not yet written to disk. The battery is designed to provide a minimum backup of 24 hours. When a RAID controller is first installed in a server, the battery may need charging.
Property Definition • • Auto — Storage Management performs an automatic learn cycle based on the set time. Warn — The learn cycle is past the default 90 days. When the battery is in Warn mode, the state of the controller is displayed as degraded. NOTE: Warn is available only on SAS controllers with firmware version 6.1 and later. Next Learn Time Displays the number of days and hours left before the controller firmware initiates the next learn cycle.
The learn cycle recalibrates the battery-integrated circuit so that the controller can determine whether the battery can maintain the controller cache for the prescribed period in the event of a power loss. While the learn cycle is in progress, the battery may not be able to maintain the cache during a power loss. If the controller is using Write-Back Cache policy, then the controller changes to Write-Through Cache policy until the learn cycle completes.

Virtual Disks 14 A virtual disk refers to a storage created by a RAID controller from one or more physical disks. Although a virtual disk may be created from several physical disks, it is viewed by the operating system as a single disk. Depending on the RAID level used, the virtual disk may retain redundant data if there is a disk failure or have particular performance attributes. NOTE: Virtual disks can only be created on a RAID controller.
Virtual Disk Considerations For Controllers In addition to the considerations described in this section, you should also be aware of the controller limitations described in Number of Physical Disks per Virtual Disk for the following controllers: • PERC 6/E and PERC 6/I • PERC H310 Adapter, PERC H310 Mini Monolithic, and PERC H310 Mini Blades • PERC H700, PERC H710 Adapter, PERC H710 Mini Blades, PERC H710 Mini Monolithic • PERC H800, PERC H810 Adapter • PERC H330 Adapter, PERC H330 Mini Monolithic,
NOTE: For more information about channel redundancy, see Channel Redundancy And Thermal Shutdown. • Rebuilding data — An failed physical disk that is used by both redundant and nonredundant virtual disks cannot be rebuilt. Rebuilding a failed physical disk in this situation requires deleting the nonredundant virtual disk.
Virtual Disk Considerations On Systems Running Linux On some versions of the Linux operating system, the virtual disk size is limited to 1TB. Before creating a virtual disk that is larger than 1TB, you should make sure that your operating system supports this virtual disk size. The support provided by your operating system depends on the version of the operating system and any updates or modifications that you have implemented.

RAID Level Virtual Disk State Scenario Result a Write to the bad block. The disk then remaps the Logical Block Addressing (LBA) to another physical location. The problem is resolved. RAID 5 Degraded One bad block on a physical disk. The controller cannot regenerate data from the peer disks because one drive is missing. This results in a virtual disk bad block. RAID 5 Ready One bad block on two physical disks at the same location. The controller cannot regenerate data from the peer disks.
One of the following scenarios may occur: • Backup operation fails on one or more files. In this case, restore the file from a previous backup. After restoring the file, proceed to step 2. • Backup operation completes without error. This indicates that there are no bad blocks on the written portion of your virtual disk. If you still receive bad block warnings, the bad blocks are in a non-data area. Proceed to step 2. 2.

NOTE: After the virtual disk reconfiguration process starts, the read and write policies temporarily revert to the default settings until the process is completed. Related links Reconfiguring A Virtual Disk Slow And Fast Initialize Considerations For Fast Initialize The Fast Initialize task initializes all physical disks included in the virtual disk. The Fast Initialize task updates the metadata on the physical disks so that all disk space is available for future write operations.
Formatting Or Initializing A Disk To format or initialize a disk: 1. Review the virtual disk that is destroyed by the Format or Initialize and make sure that vital data is not lost. Click Blink at the bottom of the page to blink the physical disks included in the virtual disk. 2.
• There are particular considerations for deleting a virtual disk from a cluster-enabled controller. • It is recommended that you reboot the system after deleting the virtual disk. Rebooting the system ensures that the operating system recognizes the disk configuration correctly. • If you delete a virtual disk and immediately create a new virtual disk with all the same characteristics as the one that was deleted, the controller recognizes the data as if the first virtual disk were never deleted.
Changing The Policy Of A Virtual Disk Does my controller support this feature? See Supported Features. Use the Change Policy task to change the read, write, or cache policy of a virtual disk.

15 Moving Physical And Virtual Disks From One System To Another This section describes how to move physical and virtual disks from one system to another. Related links Migrating SAS Virtual Disks To Another System Required Conditions SAS Controllers Virtual disks can only be migrated to a controller that is using the same technology. For example, virtual disks on a SAS controller must be migrated to a SAS controller.
The migration is complete. The virtual disk is now manageable through Storage Management.
16 Protecting Your Virtual Disk With A Hot Spare When you create a virtual disk using a RAID controller, it enables the system to continue functioning even during a disk failure. This feature can be enabled by assigning a hot spare to the virtual disk. When a disk fails, the redundant data is rebuilt onto the hot spare without interrupting system operations.
Related links Assigning And Unassigning Dedicated Hot Spare Assigning And Unassigning Global Hot Spare Dedicated Hot Spare Protection Policy Table 31. Hot Spare Properties Property Definition RAID Level Indicates the RAID level(s) for which you want to configure the hot spare protection policy. Minimum Number of Disks Indicates the minimum number of physical disks to be assigned as dedicated hot spares for the selected RAID level(s).
Considerations For Hot Spare Protection Policy • The dedicated hot spare protection policy is not applicable to SAS/iR, PERC, and H200 controllers. • RAID 0 does not support hot spares or protection policy. • For SAS/iR and PERC H200 family of controllers, you can assign only two global hot spares.
A dedicated hot spare can only be assigned to the set of virtual disks that share the same physical disks. A global hot spare is assigned to all redundant virtual disks on the controller. A global hot spare must be the same size (or greater) as the smallest physical disk included in any virtual disk on the controller.
Global Hot Spare Considerations On A SAS 6/iR The SAS 6/iR controller enables you to assign two global hot spares. The controller firmware remembers the hot spare assignment even after the physical disks that you assigned as hot spares have been removed. In other words, in the case of a disk removal, the firmware may assume that a hot spare is present when it is not.
CacheCade Using Solid-State Drives 17 CacheCade is used to improve random read performance of the solid-state drive (SSD) based virtual disks. A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. SSDs significantly increase the I/O performance (IOPS) and/or write speed in Mbps from a storage device. With storage controllers, you can create a CacheCade using SSDs. The CacheCade is then used for better performance of the storage I/O operations.

Related links Drivers And Firmware Drivers And Firmware Storage Management is tested with the supported controller firmware and drivers. In order to function properly, the controller must have the minimum required version of the firmware and drivers installed. The most current versions can be obtained from the support site. NOTE: You can verify which firmware and drivers are installed by selecting the Storage object in the tree view and clicking Information/Configuration.
Replacing The Disk To replace the failed disk that is part of a redundant virtual disk: 1. Remove the failed disk. 2. Insert a new disk. Make sure that the new disk has equal or greater memory space than the one you are replacing. On some controllers, you may not be able to use the additional space by inserting a disk that has a higher memory space. A rebuild is automatically initiated because the virtual disk is redundant.
After retrieving any viable data from the disk, replace the failed disk as described previously in Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk or Replacing A Failed Physical Disk That Is Part Of A Non-Redundant Virtual Disk.
• There is no hot spare assigned to the virtual disk — As long as the virtual disk is redundant, to rebuild it: – Remove the failed physical disk and replace it. A rebuild automatically starts on the new disk. – Assign a hot spare to the virtual disk and then perform a rebuild. • You are attempting to rebuild onto a hot spare that is too small — Different controllers have different size requirements for hot spares.
• The controller may be performing other tasks, such rebuilding a physical disk, that must run to completion before the controller can create the new virtual disk.

Alerts 2146 Through 2150 Received During A Rebuild Or While A Virtual Disk Is Degraded Perform the following steps: 1. Replace the damaged physical disk. 2. Create a new virtual disk and allow the virtual disk to completely resynchronize. 3. Restore data to the virtual disk from the backup. While the resynchronization is in progress, the status of the virtual disk is Resynching.
Erroneous Status And Error Messages After A Windows Hibernation Activating the Windows hibernation feature may cause Storage Management to display erroneous status information and error messages. This problem resolves when the Windows operating system recovers from hibernation.
Physical Disks Are Displayed Under The Connector Object Instead Of The Enclosure Object Storage Management surveys the status of physical disks at frequent intervals. When the physical disk is located in an enclosure, the data reported by the SCSI Enclosure Processor (SEP) is used to determine the status of the physical disk. When the SEP is not functioning, Storage Management can survey the status of the physical disk, but cannot identify the physical disk as being located in the enclosure.
