Figure 10 - Using Cascading to create a RAID 10 configuration
Note: For the first release, you can only use the SteelVine Manager GUI to monitor and configure the
storage policy for the top-level node in a cascaded configuration. All subordinate nodes must be
configured using the rotary switch or by hard-strapping of the Configuration Pins.
Drive Locking (not implemented yet)
The Drive Locking feature allows you to protect the contents of the hard disk drives that are
connected to your SteelVine Storage Reference Design, so that the contents cannot be accessed
by any other user. For the SiI5744, SiI5734 and SiI5723 SteelVine Storage Processors, you can
specify your own private password (up to 32 characters) to enable security and lock all of the
hard drives on your system (or each drive separately if your SteelVine Storage Reference Design
is set to JBOD mode). Once security is enabled and the hard drives are locked, any attempt to
access that data will be rejected until you have un-locked the drives by specifying the same
password that was entered to lock the drives. If you have a cascaded configuration consisting of
multiple SteelVine Storage Processor-based products, you apply the Drive Locking password to
the top-level node, and it will be propagated to all subordinate nodes. Similarly, to unlock all of
the drives in a cascaded configuration, you must re-enter the password through the top-level
node. After the drives are unlocked, they will remain unlocked for the duration of your current
session, and you can access the data stored on those hard drives. However, if you turn the power
off or disconnect one or more drives, the drives will revert to a locked state. If you are no longer
concerned about data security, you can disable the Security feature entirely, and the password
will no longer be needed to access your data.
Note that you must remember the password that you specified to initially lock the drives, since
you must re-enter that same password to un-lock those drives. If you forget your password, there
is no way to recover the data from the locked drives, and the drives will be unusable. If that
happens, the only way to continue using those drives is to securely erase and unlock those drives,
but any protected data will be permanently lost.
To use this feature, all of your hard disk drives must be capable of supporting the ATA Security
Commands. Refer to the list of qualified hard disk drives at
http://www.steelvine.com. This
feature is only supported with the SiI5744, SiI5734 and SiI5723 SteelVine Storage Processors.
The SiI5733 Storage Processor is programmed with an internal unique password that is used to
automatically lock and unlock the hard drives, so no user interaction is required.
