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.
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. Storage Management generates alerts 2131 and 2132 when it detects unsupported firmware or drivers on a controller. For information on alert messages, see the Server Administrator Messages Reference Guide.

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.

Blinking And Unblinking A PCIe SSD The Blink task allows you to find a device within a system by blinking one of the LEDs on the device. You can use this task to locate a failed device. Select Unblink to cancel the Blink task or to stop the LED on a physical device that is blinking indefinitely. Enabling Full Initialization On A Micron PCIe SSD Does my controller support this feature? See Supported Features. CAUTION: Full Initialization permanently erases all data present on the disk.
NOTE: Orderly hot swap is only supported when PCIe SSDs are installed in a supported system running a supported operating system. To ensure that you have the correct configuration for your PCIe SSD, see the system-specific Owner's Manual. NOTE: The Prepare to Remove task is not supported for PCIe SSDs on VMware vSphere (ESXi) systems. Select the Prepare to Remove task to safely remove a PCIe SSD from the system. This task causes the status LEDs on the device to blink.
Adding PCIe SSDs To Fluid Cache Pool You can configure or increase the capacity of the Fluid Cache pool by adding PCIe SSDs. NOTE: This task is only supported on Micron PCIe SSDs. To add a PCIe SSD to a cache pool: 1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects. 2. Expand the PCIe SSD Subsystem object. 3. Expand the Enclosure (Backplane) object. 4. Expand the Physical Devices object.
When the last but one PCIe SSD is removed from the Fluid Cache pool, the cache pool high availability changes from True to False indicating that the cache pool is Write Through capable only and the operational cache mode for any Fluid Cache disk configured for Write Back changes to Write Through. When the last PCIe SSD is removed from the Fluid Cache pool, the operational cache mode for all Fluid Cache disk changes to Pass Through.
Fluid Cache For DAS 6 Fluid Cache is a server-side caching accelerator that makes high-speed Express Flash (PCIeSSD) a shared, distributed resource. Fluid Cache enables the caching of active data working sets from storage closer to the compute tier to enable accelerated response times for latency sensitive customer workloads using Direct Attached Storage (DAS) external storage architectures. The Storage Management application facilitates addition of PCIe SSDs to the Fluid Cache pool.

Controller — Supported RAID Levels RAID controllers may support different RAID levels. For information on supported RAID levels for a controller, see Supported Features. Controller — Supported Stripe Sizes When creating a virtual disk, you must specify the stripe size for the virtual disk. Different controllers have different limitations on the stripe sizes they can support.
performance since subsequent read requests can retrieve data quickly from the cache then from the disk. However, data loss may occur in the event of a system failure which prevents that data from being written on a disk. Other applications may also experience problems when actions assume that the data is available on the disk. • • • 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.
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. The cache policies are: • Enabled — Disk Cache Policy is enabled. • Disabled — Disk Cache Policy is disabled.
Non-RAID SAS Controllers The following non-RAID controllers use Serial Attached SCSI (SAS) technology: • SAS 5/i Integrated • SAS 5/E • SAS 6 Gbps Adapter • LSI SAS 9207-8e • LSI SAS 9300-8e • LSI SAS 9206-16e • SAS 12 Gbps Adapter Firmware Or Driver Versions Use the firmware or driver versions window to view information about the controller firmware and drivers.

This task is supported on H310 and H330 controllers.
Virtual Disks 15 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 5/E and PERC 5/I • 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,
• • 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. Disk group concept consideration for S110 — Disk grouping is a logical grouping of disks attached to a RAID controller on which one or more virtual disks are created, such that all virtual disks in the disk group use all of the physical disks in the disk group.
spans is limited, the number of physical disks that can be used is also limited. The limitations on stripes and spans affect the possibilities for concatenation and RAID levels as follows: • • • Maximum number of spans affects RAID 10, RAID 50, and RAID 60. Maximum number of stripes affects RAID 0, RAID 5, RAID 50, RAID 6, and RAID 60. Number of physical disks in a mirror is always 2. This property affects RAID 1 and RAID 10.
NOTE: Channel redundancy only applies to controllers that have more than one channel and that attach to an external disk enclosure.

Managing Virtual Disk Bad Block Management Virtual disk bad blocks are bad blocks on one or more member physical disks. The read operation on the virtual disks having bad blocks may fail. Storage Management generates a critical alert (2387) to notify you of the bad blocks on the virtual disk. Virtual disk bad blocks are discovered when the controller performs any operation that requires scanning the disk.
RAID Level Virtual Disk State Scenario Result RAID 5 Ready One bad block on two physical disks at the same location. The controller cannot regenerate data from the peer disks. This results in a virtual disk bad block. RAID 6 Partially degraded (one failed/missing physical disk) One bad block on a physical disk. The controller regenerates data from the peer disks and sends a Write to the bad block. The disk then remaps the LBA to another physical location. The problem is resolved.

16 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 PERC 5/E, PERC 5/i, and SAS 5/iR Controllers You can migrate physical and virtual disks from one controller, enclosure, or server to another.
5. Use the Foreign Configuration Operations task to import the migrated virtual disks on the receiving controller. NOTE: The Foreign Configuration Operations are not supported on PERC S100, S110, S130, and S300 controllers. The migration is complete. The virtual disk is now manageable through Storage Management.
17 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.
Dedicated Hot Spare Protection Policy Table 35. 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). Severity Level Displays the severity level you want to assign to the generated alert, if this policy is violated.
• For SAS/iR and PERC H200 family of controllers, you can assign only two global hot spares. • If the status of the virtual disk is displayed as Degraded or Failed because of the hot spare protection policy violation, then assign the required number of hot spares (as defined in the protection policies) for the status to be displayed as normal. • Hot Spare Protection Policy is not applicable to PERC S100, S110, S130, and S300 controllers.
In this case, you can unassign the global hot spare after creating a new virtual disk and then assign a new and larger hot spare to cover all redundant virtual disks on the controller. To determine whether the controller is using SCSI or SAS technology, see RAID Controller Technology: SCSI, SATA, ATA, and SAS.
circumstance, a disk not previously assigned as a global hot spare becomes a hot spare through failure or removal. To ensure that the controller firmware always has a healthy physical disk as a global hot spare: • Unassign the hot spare that is assigned as a global hot spare before removing and reassigning a physical disk that is assigned as a global hot spare, unassign the hot spare before removal and reassign another physical disk as the global hot spare.
CacheCade Using Solid-State Drives 18 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.
The CacheCade(s) page is displayed. 1. In the Server Administrator window, under the System tree, expand Storage. 2. Click a storage controller. For example: PERC H710P Adapter. 3. Click a storage controller component. 4. Under Available Tasks, select Manage CacheCade. 5. Click Execute. The CacheCade(s) page is displayed. Related Links CacheCade Using Solid-State Drives CacheCade Properties The CacheCade(s) page displays a table of properties for each CacheCade.
CacheCade size = capacity of the smallest SSD * the number of SSDs 4. From the available free disks that are displayed, select the SSDs that you would like to include in the CacheCade. The selected disks are displayed in the Physical Disks Selected section. 5. Click Finish. NOTE: The procedure of selecting physical disks while creating a CacheCade is similar to the selection of disks while creating a virtual disk.
Troubleshooting 19 This section contains troubleshooting procedures for common situations as well as for specific problems. Related Links Common Troubleshooting Procedures Virtual Disk Troubleshooting Specific Problem Situations And Solutions PCIe SSD Troubleshooting Fluid Cache For DAS Common Troubleshooting Procedures This section describes commands and procedures that can be used in troubleshooting.
System Requirements Make sure that the system meets all system requirements. In particular, verify that the correct levels of firmware and drivers are installed on the system. 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.
Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk If the failed disk is part of a redundant virtual disk, then the disk failure will not result in data loss. You must replace the failed disk immediately, however, as additional disk failures can cause data loss. If the redundant virtual disk has a hot spare assigned to it, then the data from the failed disk is rebuilt onto the hot spare.
Using The Physical Disk Online Command On Select Controllers Does my controller support this feature? See Supported Features. If you do not have a suitable backup available, and if the failed disk is part of a virtual disk on a controller that supports the Online physical disk task, then you can attempt to retrieve data by selecting Online from the drop-down task menu of the failed disk. The online command attempts to force the failed disk back into an online state.
Virtual Disk Troubleshooting The following sections describe troubleshooting procedures for virtual disks: • Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk • A Rebuild Does Not Work • A Rebuild Completes With Errors • Cannot Create A Virtual Disk • Virtual Disk Errors On Systems Running Linux • Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks A Rebuild Does Not Work A rebuild does not work in the following situations: •
The rebuild may also report sense key errors. In this situation, take the following actions to restore the maximum data possible: 1. Back up the degraded virtual disk onto a fresh (unused) tape drive. • If the backup is successful — If the backup completes successfully, then the user data on the virtual disk has not been damaged. In this case, you can continue with step 2. • 2.
Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant virtual disks. This applies to all controllers. Using the same physical disks for both redundant and nonredundant virtual disks can result in unexpected behavior including data loss.
Receive A Bad Block Alert With Replacement, Sense, Or Medium Error The following alerts or events are generated when a portion of a physical disk is damaged: • 2146 • 2147 • 2148 • 2149 • 2150 This damage is discovered when the controller performs an operation that requires scanning the disk.
Isolate Hardware Problems A Task Menu Option Is Not Displayed You may notice that the task menus do not always display the same task options. Some tasks are only valid for certain types of objects or at certain times. For example, a Check Consistency task can only be performed on a redundant virtual disk. Similarly, if a disk is already offline, the Offline task option is not displayed. There may be other reasons why a task cannot be run at a certain time.
