The following table shows the specifications of the host affinity function:
Table 5.2 Host affinity function specifications
*1: The maximum number of host information (HBAs) that can be registered. A WWN is registered as the host informa-
tion when the HBA of the connected server is FC/FCoE. A SAS address is registered for a SAS HBA and the iSCSI name
and IP address are registered as a set for an iSCSI HBA.
When there are two host interface ports for each ETERNUS DX Disk storage system, the maximum number of con-
nectable hosts is 512. Since the maximum number of connectable hosts for each port is 256, the maximum number
of connectable hosts for each ETERNUS DX Disk storage system is 256 × the number of ports when the number of
host interface ports is 4 ports or less.
*2: The maximum number of LUNs that can be set varies depending on the connection operation mode of the host
response settings. For details on the mode, refer to "5.5.5 Connection Operation Mode" (page 73)
.
*3: This value is for AIX mode, NR1000V mode, HP-UX mode, or BS2000 mode.
*4: This value is for AIX mode or NR1000V mode.
*5: This value is for HP-UX mode.
*6: This value is for BS2000 mode.
5.2.4 Data Encryption
Encrypting data as it is being written to the drive prevents information leakage caused by fraudulent
decoding.
Even if a drive is removed and stolen by malicious third parties, data cannot be decoded.
The encryption function only encrypts the data stored on the drives, so server access results in the
transmission of plain text. Therefore, this function prevents data leakage from drives that are physically
removed, but does not prevent data leakage from server access.
The following two types of data encryption are supported:
• Self Encrypting Drive
Data encryption with the encryption function of a Self Encrypting Drive (SED) that performs self encryption
• Volume conversion encryption
Data encryption with the encryption function of the firmware for the ETERNUS DX Disk storage system on a
volume basis
Encryption using SEDs is recommended because SEDs do not affect system performance.
