How does the Channel Gateway eject tapes?
A: For disk based storage, an eject (rewind/unload) is
simply the process of making the virtual tape data no longer available. For
true tape-based storage, an eject command is issued to the dri...
- What is the storage capacity overhead introduced by the Channel Gateway?
A: The overhead is very small – usually in the range of .05%
to .10% of the total storage capacity.
The overhead is 8 bytes per tape block.
Thus if you write a 10 Gbyte tape using a bl...
- How is end-of-tape handling performed?
A: A virtual tape can reach end-of-tape under the following conditions:
The storage capacity has reached a minimum configured value;
the maximum configured amount of data has been written to ...
- How many virtual tapes can be supported?
A: Channel Gateway imposes no limits on the number of tapes for disk-based
storage applications. The limit is defined by the file system or storage device.
- Can multiple Channel Gateways access the same data?
A: Yes. If the storage allows access, such as NFS and clustered file system environments, all Channel
Gateway servers can read and write the shared data. If the storage is SCSI or
Fibre-Channel, add...
- How much data is pre-allocated for each virtual tape?
A: No storage is reserved for a virtual tape.
Unlike true tape, there is no wasted space on the storage device.
- Can other applications access the Channel Gateway data?
...ta, the virtual tape data will be available to other
applications that have physical access to the storage device. The Channel Gateway provides unique
capabilities to share data simultaneously betw...
- Can multiple Scratch pools be defined and managed?
...are used by many of our
customers. This allows them to better
manage and utilize their available storage capacity.
- How does the Channel Gateway determine which storage pool to use when a scratch tape is mounted?
A: The Channel Gateway can easily be configured regarding which
storage pool / filesystems to use. The selection mechanism is script based and
easily modified by Luminex engineers. The two defa...
- Are there any tape label restrictions?
... There are no tape label restrictions. The Channel Gateway supports many different
mainframe tape storage products and their associated tape labeling conventions.
- How does Channel Gateway work with open-system backup software such as Tivoli and Netbackup?
A: The integration to these products is transparent to the
Channel Gateway.
- Does the system need to be on the customer network?
A: No, unless the storage system is to be accessed via NFS and resides on the customer network storage or
if the Luminex browser interface is to be used over the network.
- What storage interfaces are supported?
A: Any device that can be seen by the native Sun Solaris
system. Storage devices can be SCSI, iSCSI, Fibre-Channel, and NFS.
- Will the Channel Gateway support multiple filesystems?
A: Yes, not only will the Channel Gateway support multiple
filesystems (i.e. storage pools), but it can also support different filesystems
on the same server.
- Does Channel Gateway/CGX support Data Domain OS 5.2.1.0?
...rs around the world are using Channel Gateway and Channel Gateway X (CGX) with attached Data Domain storage systems running DD OS 5.2.1.0. Channel Gateway was designed from the ground up for maximum c...
- How is the server and storage status monitored from the mainframe?
A: Using Luminex's mainframe software Admin+, information such as filesystem capacity,
server health, scratch tape monitoring, and many other actions and status can
be initiated from the mainfr...
- Does Channel Gateway work in OAM environments?

solu...
- What changes are required to my current application setup?
...
A:
The upgrade and conversion process is to reconfigure the OAM application to use
tape-based storage and then to migrate the existing 3995 data to the Channel
Gateway virtual tape storage. Th...
- Is virtual tape a good fit for OAM applications?
...
A:
Yes! With the Channel Gateway a vast
array of modern, cost effective and massively scalable storage solutions are
available to replace the EOL’d 3995 devices
- How does Channel Gateway support disaster recovery?
