1OverviewofHPStorageWorks XP

Disk/Cache Partition

The HP storage system can connect to multiple hosts and be shared by multip le users, such as d ifferent departments or even different compa nies. This can cause conﬂicts among the various users. For example, if a particular host issues a large number of I/O requests, the I/O performance of other hosts may decrease. If the various ad m inistrators have different storage policies and procedures, or issue conﬂicting commands, that can cause difﬁculties. Disk/Cache Partition has t wo main functions: storage management logical partition (SLPR), and cache logical partition (CLPR).

Storage Management Logical Partition allows you to divide the available storage among various users. A storage system can be shared among several groups that may have different storage administrators. This can

cause problems if those administrators have differing or conﬂicting storage procedures, or if two or more administrators attempt to perform operations on the same logical volume, such as HP StorageWorks XP

LUN Expansion (LUSE) or HP StorageWorks XP Virtual LVI/LUN (VLL). The storage management logical partition function can allocate the storage system resources into two or more virtual storage systems, each of which can b e accessed only by the storage administrator, the storage partition administrator for that storage management logical partition, and the users for that partition.

Cache Logical Partition allows you to divide the cache into multiple virtual cache memories. If one storage system is shared with multiple hosts, and one host reads or writes a large amount of data, read and write data can require enough of the cache memory to affect other users. The cache logical partition function creates two or more virtual cache memories, with each allocated to a different host. This prevents contention for cache memory.

2 About Disk/Cac he Partition Operations

The storage systems can connect multiple hosts and can be shared by multiple de partments in an enterprise, and also shared by multiple companies. Under this circumstances, if a host issues a lot of I/O requests, the I/O performance of other hosts may decrease. If a subsystem's administrator of a department or an enterprise performs an inappropriate operation, there is a possibility that data of other departments or companies are leaked or broken. Disk/Cache Partition enables you to prevent these risks. “Overview of HP XP Disk/Cache Partition” on page 11 describes the overview of Disk/Cache Par tition and its features.

Overview of

Disk/Cach Par tition function

Cache Logical Partition enables you to partition the built-in cache memory in the storage system into multiple virtual cache memories. Furthermore, by allocating the partitioned virtual cache to a host, the I/O performance of other hosts can be protected from decreasing even if one host issues many I/O requests.

Storage Management Logical Partition enables you to partition a subsystem into multiple virtual subsystems. Because the administrator of the virtual subsystem cannot access the other virtual subsystem that

torage Management Logical Partition.

Storage Management Logical Partition (SLPR)

Storage system can be shared with the plural organizations, for example, enterprises, and depa rtments within the enterprise. Therefore, the plural administrators who a re belonged in the different organizations may manage one subsystem. Under this circumstances, an administrator who is belonged in an organization is potentially destroying the volumes of other organizations. Furthermore, there is a risk of deriving a complicated a nd difﬁcult management of storage system because of an incorrect operation by an administrator and its inﬂuence to the other organizations. The storage management logical partition function of Disk/Cache Partition can allocate all resources of one subsystem, that is, ports and CLPRs, to the plural virtual subsystem. Each virtual subsystem can be accessed by each administrator only. Therefore, the risks of which an administrator destroys the volumes of other organization, and the data of an organization leaks can be prevented. Figure 1 on page 1 4 shows an example of which one subsystem is partitioned to two virtual subsystems. Each virtual subsystem is allocated to two enterprises respectively. In this case, the subsystem administrator of enterprise A can manage the virtual subsystem of enterprise A, but cannot manage one of enterprise B. By the same token, the subsystem administrator of enterprise B can manag e the virtual subsystem of enterprise B, but cannot manage one of enterprise A.

The virtual subsystem that is created by the storage system's partitioned referred to as the SLPR (s management l created in one subsystem. See “Launching Disk/Cache Partition” on page 33 for creating SLPR.

Cache Logical Partition (CLPR)

If one storage system is shared with multiple hosts, and one host in these hosts reads or writes a large amount of data, the read and write data of the host may occupies the large area in the cache memory of the

storage system. Under this circumstances, other hosts slow down the read/write speed since other hosts must wait for a chance to write into the cache mem ory. The cache logical partition function of

Disk/Cache Partition can partition the cache memory of the storage system. The par titioned cache memories a re used as the virtual cache memories, and each of them is allocated to each host. As a result, the situation that the speciﬁed host exclusively uses most area of cache memory can be prevented.

Figure 2 on page 15 shows an example of use for the network within a corporation. The cache memory

is partitioned to three virtual cache m em ories. Each virtual cache mem ory is allo cated to each host of three branch ofﬁces. The host of branch A is inputting and outputting a large amount of data to or from storage system. However, the read and write data of the host of branch A does not occupy the cache memory because the capa city of cache that the host of branch A can use is limited to 40 Gbytes. Even if thehostofbranchAaccessesalargeamountofdata, thehosts of otherbranchesdoesnot slow

down the read/write speed und er the inﬂuence of data access amount of branch A. The hosts of other branches always can use up to 40 Gbytes cache area.

The virtual cache memory that is partitioned by using the cache logical partition function is referred to as the CLPR. Up to 32 CLPRs including CLPR0 which is provided as a default can be created in one subsystem. See “Cache Logical Partition Operations”onpage35for creating CLPR.

Note:

Though you usually need the license key to use the Cache Logical Partition function of Disk/Cache

The administrators of storage systems are categorized into two types, the storage administrator and the storage partition administrator. The storage administrator may logical partition the storage system and the cache memor y by creating SLPRs and CLPRs. The storage administrator may manage the entire storage system and all resources in the storage system, for example, SLPRs, ports, CLPRs and parity groups. As shown in Figure 3 on page 18, the storage administrator may manage all resources of SLPR1 and SLPR2.

The storage partition administrators are not permitted to create an SLPR and a CLPR. The storage partition administrators are not permitted to manage the entire subsystem, but they can manage the speciﬁed SLPR. As

shown in Figure 3 on page 18, the storage partition administrator for SLPR1 may manage only the resources of SLPR1, but he/she cannot manage the resources of SLPR2 (port C a nd CLPR3). On the other hand, the storage par tition administrator of SLPR2 may manag e only the resources of SLPR2, but he/she cannot the XP24000 Remote Web Console User’s Guide.

Possible Interacting and Conﬂicting Functions

The storage partition administrators can display only SLPR(s) which they administrate. They cannot display and also operate the SLPR(s) which they do not administrate. In addition, the functions that the storage partition administrators can operate are limited. Table 3 on page 18 lists the functions and shows whether those functions are able to be operated by the storage partition administrators or not.

The other notes on the Disk/Cache Partition operations are as follows:

• The storage partition administrators cannot make settings on plural SLPRs.

Note:

HP recommends that you do not m ake settings on the plural SLPRs even if you are logged into theRemoteWeb Consoleasastorageadministrator. If a storage administrator makes settings on plural SLPRs, the administration of SLPR will become complex and difﬁcult.

• If the storage administrator performs forcibly the following functions for the plural SLPRs, and

consequently some contradictions occur, the use of SLPR by the storage partition administrator will be affected. Manual MigrationwithAutoLUN Business Copy Quick Restore The LU path settings and the settings of High Speed mode with LUN Manager

XP24000 Disk/Cache Partition User's Guide

Creation of a LUSE volume

• Adding or changing the deﬁnition of the CLPR requires several hours or more.

• The m ainframe volumes must be allocated to SLPR0. All operations of the mainframe volumes can

be performed by the storage administrators, not the storage partition administrators.

• The target ports must be allo cated to the SLPRs other than SLPR0.

• We do not recommend that the following operations with CLPRs are performed.

Creation of a LUSE volume that extends over multiple CLPRs

Note:

If this operation is forcibly performed, the volumes belonging to the CLPRs which LUSE is set

to cannot

be used as the Continuous Access or the TrueCopy for M a inframe pair volume. Business Copy Quick Restore operation that affects mu ltiple CLPRs Manual Migration of Auto LUN that affects multiple CLPRs

• If theoperationsofHPStorageWorksXPContinuousAccessAsynchronousorTrueCopy

Asynchronous for Mainframe are performed, and the volumes which are extended over multip le CLPRs are allocated to the same consistency group, a pair cannot be created.

• If the operations of Continuous Access Asynchronous or TrueCopy Asynchronous for Mainframe

are performed, only Continuous Access Asynchronous pairs or TrueCopy A synchronous for Mainframe pairs that belong to the same CLPR can be allocated to one c onsistency group. The parity groups allocated to the CLPR that these Continuous Access Asynchronous pairs or TrueCopy Asynchronous for Mainframe pairs belong to cannot migrate to another CLPR.

• The parity g roup that contains the LDEVs to which the Cache Residency ca che extents is deﬁned

cannot migrate to another CLPR.

• Continuous Access Journal data volumes and journal volumes do not need to belong to the

same CLPR.

• When the CU numbers are allocated to the SLPR:

Before a customized volume (CV) is created, the storage administrator must allocate the CU numbers to the SLPR. These allocated CU numbers are necessary only for deﬁning the CU number that will be allocated to the LDEV when the storage partition administrator will create a customized volume.

Figure 4 on page 21 shows an example of the Manual Migration of the volumes using the Auto

LUN function. This example indicates that the volume LDKC00:CU01:LDEV05 migrates from SLPR1 to SLPR2, and the volume LDKC00:CU02:LDEV10 migrates from SLPR2 to SLPR1. CU01 is

allocated to SLPR1. The volume LDKC00:CU01:LDEV05 belonged to CU01 before Manual Migration was performed. However, after Manual Migration is performed, the volume LDKC00:CU02:LDEV10 will be allocated to CU01 in SLPR1. Therefore, the CU number will not correspond with the volume number in SLPR1. By the same token, the CU number will not correspond with the volume num b er in SLPR2 after Manual Migration is performed. Even if the CU number does not correspond with the volume number in the SLPR, an error do es not occur. Since such a discrepancy, however, will make the

administration of s ubsystem difﬁcult, the special attentions are required when a storage administrator forcibly performs the Manual Migration function of Auto LUN between the different SLPRs. For further information on the customized volume, see the HP StorageWorks XP24000 Virtual LVI/LUN (VLL) and Volume Shredder User’s Guide. For fur ther information on M anual Migration of

Auto LUN, see the HP StorageWorks XP24000 Auto LUN Software User's Guide.

From the License Key Partition Deﬁnition window (see Figure 5 on page 24), storage administrators can partition the licensed capacity for SLPRs. On the License Key Partition Deﬁnition window, the program product options for which the licensed capacity can be partitioned are listed.

The program product options have to be installed from the License Key window before the licensed capacity for them are partitioned.

To open the License Key Partition Deﬁnition window, click Go, Environmental Settings, and then License Key Partition Deﬁnition on the menu bar of the Remote Web Console main window.

The Partition Status list and the Setting box have the following features:

• The Partition Status list displays the status of the pa rtitioned licensed capacity of the program

product that is selected in the program product list for each SLPR. The Partition Status list consists of the

following items:

• SLPR Name - displays the name of SLPR.

• Used Volume - displays the currently used licensed capacity for the program product that is

selected in the program product list.

• Status - displays the status that is ﬁgured out by comparing the allocated licensed capacity

(Permitted Volumes) and used licensed capacity (Used Volumes). The following status can be displayed: Installed: When the program product with the unlimited licensed capacity is selected in the list, this status indicates that the license is allocated to the SLPR. When the program product that is not with the unlimited licensed capacity is selected in the list, this status indicates that the

partitioned licensed capacity is allocated to the SLPR and the allocated licensed capacity

more than the capacity of Used Volumes. This status means that the storage partition administrator can use the program product in the allocated SLPR. Not Installed: No license and licensed capacity for the selected program product are allocated to the SLPR. Capacity Insufﬁcient: The licensed capacity that is allocated to the SLPR (Permitted Volumes) is

less than the currently used licensed capacity (Used Volumes). When the trial period still remains, the number of remaining days are displayed in parentheses. Not Enough: The licensed capacity is insufﬁcient thoug h a program product is installed.

• Permitted Volumes - displays nothing when the program product with the unlimited licensed capacity is selected in the list, or displays the allocated licensed capacity to the SLPR in GB when the p rogram product that is not with the unlimited licensed capacity is selected in the list.

• The displayed items in the Setting box depend on the program product selected in the list.

When the

program product with the unlimited licensed capacity or that does not depend on the licensed capacity is selected in the list, the Enable button and the Disable button are displayed (see

Figure 9 on page 26). To allocate the license of the selected program product to the SLPR,
