Storage Modes
The RamSan-810 supports a variety of different Storage Modes. Each mode is tailored to a
common use case for a high capacity Solid State Disk.
Warning:
Switching between Storage Modes is a destructive action and will cause data loss. Please
backup all data and contact Texas Memory Systems, Inc. (Section 9.3) before switching
Storage Modes.
5.13.1
Max Capacity
This is the default Storage Mode used by the RamSan-810. This mode is the most flexible and is
useful in an environment where the entire capacity of the unit is needed. Max Capacity allows the
RamSan-810 administrator to create Logical Units and assign Access Policies as needed. This
mode is recommended for deployments where the RamSan-810 is mirrored or preferred read
mirrored to other storage.
Warning:
If maintenance is performed that requires the replacement of a flash card in the RamSan-
810, all of the data will need to be restored from a backup after the maintenance.
5.13.2
JBOF
This Storage Mode automatically creates one Logical Unit for each Flashcard present in the
RamSan-810. The administrator can then assign Access Policies as needed. JBOF (Just a Bunch
Of Flash) mode is useful in an environment where a host-based software RAID can be created to
increase redundancy across the Flashcards.
Notice:
This feature requires a license to be installed on the system.
5.13.3
Data Acquisition
This Storage Mode creates one Logical Unit and assigns Access Policies to all interface ports.
This mode is used to present the entire storage space to all connected devices.
