Page 23: Figure 2 Raid6-Fr Concept
2. Basic Functions RAID Functions ● RAID6-FR (Striping with Double Distributed Parity which Provides High-Speed Rebuild Capabilities) Distributing multiple data groups and reserved space equivalent to hot spares to the configuration drives makes it possible to recover from up to two drive failures. RAID6-FR requires less build time than RAID6. Figure 2 RAID6-FR Concept Data writing request...
Page 24: User Capacity (Logical Capacity)
2. Basic Functions RAID Functions ■ Recommended RAID Level Recommended RAID levels are RAID5 and RAID6. For SSDs, a RAID5 configuration or a fault tolerant enhanced RAID6 configuration is recommended because SSDs operate much faster than other types of drive. For large capacity SSDs, using a RAID6-FR configuration, which provides excellent performance for the rebuild process, is recommended.
Page 25: Raid Group
2. Basic Functions RAID Functions RAID Group This section explains RAID groups. A RAID group is a group of drives. It is a unit that configures RAID. Multiple RAID groups with the same RAID level or multiple RAID groups with different RAID levels can be set together in the ETERNUS AF. After a RAID group is created, RAID levels can be changed and drives can be added.
Page 26: Table 9 Recommended Number Of Drives Per Raid Group
2. Basic Functions RAID Functions Note Use drives that have the same capacity to configure RAID groups. If a RAID group is configured with drives that have different capacities, all the drives in the RAID group are recognized as having the same capacity as the drive with the smallest capacity in the RAID group and the rest of the capacity in the drives that have a larger capacity cannot be used.
Page 27: Volume
2. Basic Functions RAID Functions Volume This section explains volumes. Logical drive areas in RAID groups are called volumes. A volume is the basic RAID unit that can be recognized by the server. Figure 4 Volume Concept Volume 1 Volume 3 Volume 2 RAID group 1 RAID group 2...
Page 28 2. Basic Functions RAID Functions Type Usage Maximum capacity Virtual Volume (VVOL) A VVOL is a VMware vSphere dedicated capacity virtualization 128TB volume. Operations can be simplified by associating VVOLs with virtual disks. Its volume type is FTV. Deduplication/Compression This volume is a virtual volume that is recognized by the server 128TB Volume when the Deduplication/Compression function is used.
Page 29: Hot Spare
2. Basic Functions RAID Functions Hot Spare Hot spares are used as spare drives for when drives in a RAID group fail, or when drives are in error status. Figure 5 Hot Spare Hot spare Failure RAID group Note For RAID6-FR, because a RAID6-FR group reserves an area equivalent to one drive, data can be restored to the reserved space even if a drive fails.
Page 30: Figure 6 Hot Spare Selection Criteria (For The Eternus Af650 S3)
2. Basic Functions RAID Functions ■ Selection Criteria When multiple Global Hot Spares are installed, among the drives that match the selection criteria in the order of priority for Condition 1, drives that match the selection criteria in the order of priority for Condition 2 are automatically selected as a hot spare to replace the failed drive.
Page 31 2. Basic Functions RAID Functions Search order (order of priority described in Table (Priority order 1) (Priority order 2) Design Guide...
Page 32: Data Protection
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. When data is written from the server, the Data Block Guard function adds eight bytes check codes to each block (every 512 bytes) of the data and verifies the data at multiple checkpoints to ensure data consistency.
Page 33: Disk Drive Patrol
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. Caution • The T10-DIF function can be enabled only in the Standard volume. •...
Page 34: Redundant Copy
2. Basic Functions Data Protection Caution 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.
Page 35: Rebuild
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. This ensures data redundancy.
Page 36: Fast Recovery
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.
Page 37: Copyback/Copybackless
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 12 Copyback After rebuilding has been completed, replaces the failed drive with the new drive. Failed drive RAID5 (Redundant) Copyback...
Page 38: Figure 13 Copybackless
2. Basic Functions Data Protection • Capacity 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. The Copybackless function can be enabled or disabled. This function is enabled by default. Figure 13 Copybackless After rebuilding is complete, the RAID group...
Page 39: Protection (Shield)
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 40 2. Basic Functions Data Protection Caution • 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.
Page 41: Reverse Cabling
2. Basic Functions Data Protection Reverse Cabling Because the ETERNUS AF uses reverse cabling connections for data transfer paths between controllers and drives, continued access is ensured even if a failure occurs in a drive enclosure. 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.
Page 42: Operations Optimization (Deduplication/Compression And Storage Virtualization)
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Operations Optimization (Deduplication/Compression and Storage Virtualization) Deduplication/Compression The Deduplication/Compression function analyzes duplicated data in every 8KB of the write data from the server, and writes the duplicated data only once. After the first write, the data is referenced instead of writing the same data again.

Page 45: Table 15 Method For Enabling The Deduplication/Compression Function
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Note • The performance may decline when the Deduplication/Compression function is enabled. The Deduplication/Compression function is not recommended for volumes used to store performance- sensitive data. • Batch process (or sequential access) performance significantly degrades because data is written to drives intermittently or a large amount of references and updates occur.
Page 46: Table 16 Volumes That Are To Be Created Depending On The Selection Of "Deduplication" And "Compression
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Volumes that are to be created and the Deduplication/Compression setting for TPPs where the target volumes can be created vary depending on the selection of "Deduplication" and "Compression". Volumes that are to be created •...
Page 47: Figure 19 Details Of The Deduplication/Compression Function
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) ● Deduplication/Compression Volumes The physical capacity may temporarily be larger than the logical capacity that is written because data is appended in Deduplication/Compression Volumes. If the I/O load is high, the physical capacity may run out. Monitoring the physical capacity on a regular basis and enabling SNMP notifications are recommended.
Page 48: Table 18 Target Deduplication/Compression Volumes Of Each Function
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Caution Note the following when using the Advanced Copy functions for Deduplication/Compression Volumes. • The CPU usage rate may increase depending on the EC/OPC priority setting. Be cautious of an I/O performance reduction.
Page 49: Thin Provisioning
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Thin Provisioning The Thin Provisioning function 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.
Page 50: Figure 20 Storage Capacity Virtualization
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Storage Capacity Virtualization Thin Provisioning improves the usability of the drives by managing the physical drives in a pool, and sharing the unused capacity among the virtual volumes in the pool. The volume capacity that is seen from the server is virtualized to allow the server to recognize a larger capacity than the physical volume capacity.
Page 51: Table 21 Chunk Size According To The Configured Tpp Capacity
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) The following table shows the TPP chunk size that is applied when TPPs are created.

Page 52: Table 23 Tpp Thresholds
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) ● Threshold Monitoring of Used Capacity When the used capacity of a TPP reaches the threshold, a notification is sent to the notification destination, (SNMP Trap, e-mail, or Syslog) specified using the [Setup Event Notification] function. There are two types of thresholds: "Attention"...
Page 53: Figure 21 Tpv Balancing (When Allocating Disproportionate Tpv Physical Capacity Evenly)
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) 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 (Deduplication/Compression and Storage Virtualization) ● 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.
Page 55: Figure 23 Tpv/Ftv Capacity Optimization
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) 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. Once an area is physically allocated to a TPV/FTV, the area is never automatically released.
Page 56: Flexible Tier
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) 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.
Page 57: Figure 24 Ftv Configuration
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Figure 24 FTV Configuration Chunk Chunk RAID6 RAID1+0 FTSP (High tier) FTSP (Middle tier) FTRP (Parent pool) : RAID group • Flexible Tier Pool (FTRP) An FTRP is a management unit for FTSP to be layered. Up to three FTSPs can be registered in one FTRP. This means that the maximum number of layers is three.
Page 58: Table 27 Levels And Configurations For A Raid Group That Can Be Registered In An Ftsp
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) *2: The maximum pool capacity is the capacity that combines the FTSP capacity and the Thin Provisioning Pool capacity in the ETERNUS AF. The maximum pool capacity of an FTRP is the same as the maximum pool capacity of a Flexible Tier Sub Pool. *3: Same as the maximum capacity of the Flexible Tier Sub Pools.
Page 59: Table 28 Ftrp Thresholds
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) ● Threshold Monitoring of Used Capacity When the used capacity of an FTRP or an FTV reaches the threshold, an alarm notification can be sent from ETERNUS SF Storage Cruiser. There are two types of thresholds: "Attention" and "Warning". A different value can be specified for each threshold type.
Page 60: Figure 25 Ftrp Balancing
2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) 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.
Page 61 2. Basic Functions Operations Optimization (Deduplication/Compression and Storage Virtualization) Caution • 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.
Page 62: Optimization Of Volume Configurations
2. Basic Functions Optimization of Volume Configurations Optimization of Volume Configurations The ETERNUS AF allows for the expansion of volumes and RAID group capacities, migration among RAID groups, and changing of RAID levels according to changes in the operation load and performance requirements while the system is running.
Page 63: Raid Migration
2. Basic Functions Optimization of Volume Configurations ● Striping for Multiple RAID Groups Wide Striping • Distributing a single volume to multiple RAID groups makes I/O access from the server more efficient and improves the performance. RAID Migration RAID Migration is a function that moves a volume to a different RAID group with the data integrity being guaranteed.
Page 64: Figure 28 Raid Migration
2. Basic Functions Optimization of Volume Configurations The volume number (LUN) does not change before and after the migration. The host can access the volume before, during, or after a migration without being affected by the volume number. The following changes can be performed by RAID Migration. Changing the volume type •...
Page 65: Logical Device Expansion
2. Basic Functions Optimization of Volume Configurations Refer to "Combinations of Functions That Are Available for Simultaneous Executions" (page 201) for details on the functions that can be executed simultaneously, the number of simultaneous executions, and the capacity that can be processed concurrently. Caution During RAID Migration, the access performance for the RAID groups that are specified as the RAID Migration source and RAID Migration destination may be reduced.
Page 66: Lun Concatenation
2. Basic Functions Optimization of Volume Configurations LDE works in terms of RAID group units. If a target RAID group contains multiple volumes, all of the data in the volumes is automatically redistributed when LDE is performed. Note that LDE cannot be performed if it causes the number of data drives to be reduced in the RAID group.
Page 67: Figure 32 Lun Concatenation (Volume Concatenation)
2. Basic Functions Optimization of Volume Configurations Up to 16 volumes with a minimum capacity of 1GB can be concatenated. Volumes can be concatenated up to 128TB (up to 1TB for ODX Buffer volumes). Concatenation can be performed regardless of the RAID levels of the concatenation source volume and the concatenation destination volume.
Page 68: Wide Striping
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.
Page 69: Data Encryption
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 AF storage systems.
Page 70: Encryption With Self Encrypting Drive (Sed)
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.
Page 71: Firmware Data Encryption
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 AF storage systems. The Fujitsu Original Encryption method has practically the same security level as AES-128 and the conversion speed for the Fujitsu Original Encryption method is faster than AES.
Page 72: Key Management Server Linkage
2. Basic Functions Data Encryption • 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. • SDPVs cannot be encrypted after they are created. To create an encrypted SDPV, set encryption when creating a volume.
