1. Overview Function Specification List Overview Function High-speed backup "Backup" (page 99) • Continuous business • Data can be duplicated at any point without affecting other operations. Performance tuning "Assigned CMs" (page 120) Functions that can perform tuning in order to improve "Striping Size Expansion"...
Basic Functions This chapter describes the functions that control the storage system. If Multitenancy is being used, the function that the tenant user can operate is restricted. For details, refer "Multitenancy" (page 132). RAID Functions This section explains the points to note before configuring a system using the ETERNUS DX. Supported RAID The ETERNUS DX supports the following RAID levels.
2. Basic Functions RAID Functions • RAID5 (Striping with Distributed Parity) Data is divided into blocks and allocated across multiple drives together with parity information created from the data in order to ensure the redundancy of the data. • RAID5+0 (Double Striping with Distributed Parity) Multiple RAID5 volumes are RAID0 striped.
2. Basic Functions RAID Functions User Capacity (Logical Capacity) User Capacity for Each RAID Level The user capacity depends on the capacity of drives that configure a RAID group and the RAID level. Table 6 shows the formula for calculating the user capacity for each RAID level. Table 6 Formula for Calculating User Capacity for Each RAID Level RAID level...
*2: This value is for a 30.72TB SAS SSD RAID1+0 (4D+4M) configuration. *3: This value is for a 30.72TB SAS SSD RAID1+0 (4D+4M) configuration in the ETERNUS DX600 S6. Up to two REC Disk Buffers can be installed for each ETERNUS DX.
2. Basic Functions RAID Functions The same size drives (2.5" or 3.5"), the same kind of drives (NVMe SSDs, SAS SSDs, SAS disks, Nearline SAS disks, or SEDs), and the same capacity drives must be used to configure a RAID group. Figure 2 Example of a RAID Group NVMe...
Page 29
2. Basic Functions RAID Functions • Sequential access performance hardly varies with the number of drives for the RAID group. • Random access performance tends to be proportional to the number of drives for the RAID group. • Use of higher capacity drives will increase the time required for the drive rebuild process to complete.
Number of Volumes That Can Be Created Maximum number of volumes (per RAID Maximum number of volumes (per Model group) storage system) ETERNUS DX600 S6 16,384 16,384 ETERNUS DX900 S6 65,535 65,535 A volume can be expanded or moved if required. Multiple volumes can be concatenated and treated as a single volume.
Page 31
2. Basic Functions RAID Functions Type Usage Maximum capacity Flexible Tier Volume (FTV) This volume is a target volume for layering. Data is 128TB automatically redistributed in small block units according to the access frequency. FTVs are used as the copy destination for SnapOPC+.
2. Basic Functions RAID Functions the ETERNUS DX decreases by the number of volumes for the VVOL management information that are created. Hot Spare Hot spares are used as spare drives for when drives in a RAID group fail, or when drives are in error status.
2. Basic Functions RAID Functions ■ Number of Installable Hot Spares The number of required hot spares is determined by the total number of drives. The following table shows the recommended number of hot spares for each drive type. Table 12 Number of Installable Hot Spares (1/3) Total number of drives Model...

2. Basic Functions Data Protection Data Protection Data Block Guard When a write request is issued by a server, the data block guard function adds check codes to all of the data that is to be stored. The data is verified at multiple checkpoints on the transmission paths to ensure data integrity.
2. Basic Functions Data Protection The T10-DIF function can be enabled or disabled for each volume when the volumes are created. This function cannot be enabled or disabled after a volume has been created. • The T10-DIF function can be enabled only in the Standard volume. •...
2. Basic Functions Data Protection The Maintenance Operation privilege is required to set detailed parameters. Redundant Copy Redundant Copy is a function that copies the data of a drive that shows a possible sign of failure to a hot spare. When the Disk Patrol function determines that a drive requires preventative maintenance, the data of the maintenance target drive is recreated by the remaining drives and written to the hot spare.
2. Basic Functions Data Protection Rebuild Rebuild processes recover data in failed drives by using other drives. If a free hot spare is available when one of the RAID group drives has a problem, data of this drive is automatically replicated in the hot spare.
2. Basic Functions Data Protection Fast Recovery This function recovers data quickly by relocating data in the failed drive to the other remaining drives when a drive error is detected. For a RAID group that is configured with RAID6-FR, Fast Recovery is performed for the reserved area that is equivalent to hot spares in the RAID group when a drive error occurs.
2. Basic Functions Data Protection Copyback/Copybackless A Copyback process copies data in a hot spare to the new drive that is used to replace the failed drive. Figure 13 Copyback drive Replace After rebuilding has been completed, replaces the failed drive with the new drive. Failed drive RAID5 (Redundant) Copyback...
2. Basic Functions Data Protection • Capacity • Rotational speed (10,000rpm and 7,200rpm) (*1) *1: For SAS disks or Nearline SAS disks (including SEDs) only. If different types of drives have been selected as the hot spare, copyback is performed after replacing the drives even when the Copybackless function is enabled.
2. Basic Functions Data Protection Protection (Shield) The Protection (Shield) function diagnoses temporary drive errors. A drive can continue to be used if it is determined to be normal. The target drive temporarily changes to diagnosis status when drive errors are detected by the Disk Drive Patrol function or error notifications.
Page 45
2. Basic Functions Data Protection • The target drives are disconnected and then reconnected during temporary drive protection. Even though a system status error may be displayed during this period, this phenomenon is only temporary. The status returns to normal after the diagnosis is complete. The following phenomenon may occur during temporary drive protection.
If a drive enclosure fails for any reason, access to drives installed in the drive enclosures subsequent to the failed drive enclosure is maintained because normal access paths are secured by using reverse cabling. Figure 16 Reverse Cabling (for ETERNUS DX600 S6) DE#06 DE#06 IOM#0...
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) Operations Optimization (Virtualization/Automated Storage Tiering Control) Thin Provisioning Thin Provisioning has the following features: Storage Capacity Virtualization • The physical storage capacity can be reduced by allocating the virtual drives to a server, which allows efficient use of the storage capacity.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) If the Thin Provisioning function is used, the drives must be installed as follows for the maximum pool capacity. The drive type and capacity are not restricted. Table 19 Maximum Pool Capacity and Required Number of Drives Are the Required Required drive installation slot...
The following table shows the maximum number and the maximum capacity of TPPs that can be registered in the ETERNUS DX. Table 20 TPP Maximum Number and Capacity Item ETERNUS DX600 S6 ETERNUS DX900 S6 Maximum number of pools (*1) Maximum pool capacity (*2) 98,304TB...
*1 : Chunk size is for delimiting data. The chunk size is automatically set according to the maximum pool capacity. *2: If the maximum pool capacity is set to 512PB (or 96PB for the ETERNUS DX600 S6), the chunk size can be manually set when pools are created.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) Thick When creating a volume, the physical area is allocated to the entire volume area. This can be used for volumes in the system area to prevent a system stoppage due to a pool capacity shortage during operations.
Page 52
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) • Use of Thin Provisioning is also not recommended when the OS writes meta information to the whole LUN during file system creation. • TPVs should be backed up by file. While backing up a whole TPV is not difficult, unallocated areas will also be backed up as dummy data.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) TPV Balancing A drive is allocated when a write is issued to a virtual volume (TPV). Depending on the order and the frequency of writes, more drives in a specific RAID group may be allocated disproportionately. Also, the physical capacity is unevenly allocated among the newly added RAID group and the existing RAID groups when physical drives are added to expand the capacity.
Page 54
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) ■ Balancing Level The TPV balance status is displayed by three levels; "High", "Middle", and "Low". "High" indicates that the physical capacity of TPV is allocated evenly in the RAID groups registered in the TPP. "Low" indicates that the physical capacity is allocated unequally to a specific RAID group in the TPP.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) TPV/FTV Capacity Optimization TPV/FTV capacity optimization can increase the unallocated areas in a pool (TPP/FTRP) by changing the physical areas where 0 is allocated for all of the data to unallocated areas. This improves functional efficiency.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) Flexible Tier Flexible Tier provides the following functions: • Automated Storage Tiering This function automatically reallocates data according to the data access frequency and optimizes performance and cost. • FTRP Balancing I/O access to a virtual volume can be distributed among the RAID groups in a pool by relocating and balancing the physical areas allocated to the virtual volume.

2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) Thick When creating a volume, the physical area is allocated to the entire volume area. This can be used for volumes in the system area to prevent a system stoppage due to a pool capacity shortage during operations.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) FTRP Balancing When drives are added to a pool, the physical capacity may be allocated unevenly among the RAID groups in the pool. By using the Flexible Tier Pool balancing function, the allocated physical capacity as well as the usage rate of the physical disks in the pool can be balanced.
2. Basic Functions Operations Optimization (Virtualization/Automated Storage Tiering Control) • If the free capacity in the FTSP becomes insufficient while FTRP balancing is being performed, an error occurs and the balancing session ends abnormally. Note that insufficient physical capacity cannot be replaced by other FTSPs. •...

This is used to expand the existing RAID group capacity instead of adding a new RAID group to add the volumes. ■...
2. Basic Functions Optimization of Volume Configurations RAID Migration RAID Migration is a function that moves a volume to a different RAID group with the data integrity being guaranteed. This allows easy redistribution of volumes among RAID groups in response to customer needs.
2. Basic Functions Optimization of Volume Configurations • Changing the number of concatenations and the Wide Stripe Size (for WSV) • Enabling the Deduplication/Compression function for existing volumes The following processes can also be specified. • Capacity expansion When migration between RAID groups is performed, capacity expansion can also be performed at the same time.
2. Basic Functions Optimization of Volume Configurations Logical Device Expansion Logical Device Expansion (LDE) allows the capacity of an existing RAID group to be dynamically expanded by changing of the RAID level or the drive configuration of the RAID group. When this function is performed, drives can be also added at the same time.
Page 67
2. Basic Functions Optimization of Volume Configurations For details on the functions that can be executed simultaneously and the number of simultaneous executions, refer to "Combinations of Functions That Are Available for Simultaneous Executions" (page 240). Since the data cannot be recovered after the failure of LDE, back up all the data of the volumes in •...
2. Basic Functions Optimization of Volume Configurations LUN Concatenation LUN Concatenation is a function that is used to add new area to a volume and so expand the volume capacity available to the server. This function enables the reuse of leftover free area in a RAID group and can be used to solve capacity shortages.
2. Basic Functions Optimization of Volume Configurations Figure 31 LUN Concatenation (Volume Concatenation) 10GB Concatenation Unused area 20GB 30GB 60GB Only Standard type volumes can be used for LUN Concatenation. The encryption status of a concatenated volume is the same status as a volume that is to be concatenated. LUN Concatenation may not be available when other functions are being used in the ETERNUS DX or the target volume.
2. Basic Functions Optimization of Volume Configurations Wide Striping Wide Striping is a function that concatenates multiple RAID groups by striping and uses many drives simultaneously to improve performance. This function is effective when high random write performance is required. I/O accesses from the server are distributed to multiple drives by increasing the number of drives that configure a LUN, which improves the processing performance.
AES (*1) or Fujitsu Original Encryption can be selected as the encryption method. The Fujitsu Original Encryption method uses a Fujitsu original algorithm that has been specifically created for ETERNUS DX storage systems.
2. Basic Functions Data Encryption Encryption with Self Encrypting Drive (SED) An SED has a built-in encryption function and data can be encrypted by controlling the encryption function of an SED from the controller. An SED uses encryption keys when encrypting and storing data. Encryption keys cannot be taken out of the drive.
The encryption method can be selected from the world standard AES-128, the world standard AES-256, and the Fujitsu Original Encryption method. The Fujitsu Original Encryption method that is based on AES technology uses a Fujitsu original algorithm that has been specifically created for ETERNUS DX storage systems.
Page 74
2. Basic Functions Data Encryption • It is recommended that the copy source volume and the copy destination volume use the same encryption method for Remote Advanced Copy between encrypted volumes. • When copying encrypted volumes (using Advanced Copy or copy operations via server OS), transfer performance may not be as good as when copying unencrypted volumes.
2. Basic Functions User Access Management User Access Management Account Management The ETERNUS DX uses roles to allocate access authority when a user account is created, and sets which functions can be used depending on the user privileges. Since the authorized functions of the storage administrator are classified according to the usage and only minimum privileges are given to the administrator, security is improved and operational mistakes and management hours can be reduced.
2. Basic Functions User Access Management • Roles and available functions Seven default roles are provided in the ETERNUS DX. The following table shows the roles and the available functions (privileges). Table 33 Available Functions for Default Roles Roles Privilege Software Storage Account...
2. Basic Functions User Access Management User Authentication Internal Authentication and External Authentication are available as login authentication methods. RADIUS authentication can be used for External Authentication. ■ Internal Authentication Internal Authentication is performed using the authentication function of the ETERNUS DX. The following authentication functions are available when the ETERNUS DX is connected via a LAN using operation management software.

2. Basic Functions User Access Management Audit Log The ETERNUS DX can send information such as access records by the administrator and setting changes as audit logs to the Syslog servers. Audit logs are audit trail information that record operations that are executed for the ETERNUS DX and the response from the system.
2. Basic Functions Improving Host Connectivity Improving Host Connectivity Host Affinity The host affinity function prevents data from being damaged due to inadvertent storage access. By defining a server that can access the volume, security can be ensured when multiple servers are connected.

2. Basic Functions Improving Host Connectivity iSCSI Security For an iSCSI interface, the iSCSI authentication function can be used when the initiator accesses the target. The iSCSI authentication function is available for host connections and remote copying. The Challenge Handshake Authentication Protocol (CHAP) is supported for iSCSI authentication. For CHAP Authentication, unidirectional CHAP or bidirectional CHAP can be selected.
2. Basic Functions Environmental Burden Reduction Environmental Burden Reduction Eco-mode Eco-mode is a function that reduces power consumption for limited access disks by stopping the disks rotation during specified periods or by powering off the disks. Disk spin-up and spin-down schedules can be set for each RAID group or TPP. These schedules can also be set to allow backup operations.
2. Basic Functions Environmental Burden Reduction • FTSP For RAID groups with the following conditions, the Eco-mode schedule can be set but the disks motor cannot be stopped or the power supply cannot be turned off: SDPVs are registered • ODX Buffer volumes are registered •...
Page 85
2. Basic Functions Environmental Burden Reduction • To set Eco-mode schedules, use ETERNUS Web GUI, ETERNUS CLI, ETERNUS SF Storage Cruiser, or ETERNUS SF AdvancedCopy Manager. Note that schedules that are created by ETERNUS Web GUI or ETERNUS CLI and schedules that are created by ETERNUS SF Storage Cruiser or ETERNUS SF AdvancedCopy Manager cannot be shared.
Page 86
2. Basic Functions Environmental Burden Reduction The operation time of disks varies depending on the Eco-mode schedule and the disk access. • Access to a stopped disk outside of the scheduled operation time period causes the motor of the stopped disk to be spun up, allowing normal access in about one to five minutes. When a set time elapses since the last access to a disk, the motor of the disk is stopped.
2. Basic Functions Environmental Burden Reduction Power Consumption Visualization The power consumption and the temperature can be visualized with a graph by using the ETERNUS SF Storage Cruiser integrated management software in a storage system environment. The ETERNUS DX collects information on power consumption and the ambient temperature. Collected information is notified using SNMP and graphically displayed on the screens by ETERNUS SF Storage Cruiser.
■ ETERNUS SF ETERNUS SF can manage storage environments that center on Fujitsu storage products. An easy-to-use interface enables complicated storage environment design and setting operations, which allows easy installation of a storage system without needing to have high level skills.

A. Specifications Function Specifications Update Information Management of REC A separate copy control bitmap is required for REC in both (source and destination) ETERNUS DX storage systems to manage and control update information. The update information during the suspended state is managed only within each ETERNUS DX and during the resumed state, the update information in both ETERNUS DX storage systems is merged and only the areas where the data in the copy source and copy destination differs are copied.
