How do you manage HA DDP?

Flowingweb — Thu, 22 Oct 2020 11:38:08 +0000

HA DDP comes with HA A/V FS on board. HA AVFS is managed by admin using the web interface. Although possible, there is no need for users to be confronted with the web interface.

HA A/V FS is an in house development of Ardis Technologies. This has the advantage that issues can be solved without having to consult another party. A short reaction time is guaranteed this way. HA A/V FS is the property of Ardis Technologies, manufacturer of the Dynamic Drive Pool, in short DDP series of storage servers

Archiware P5 comes standard as part of A/V FS. In a smaller setup P5 can be used to control a tape streamer or other SAS equipped library device. Or it can be used as client. When HA AVFS is used it is best to use a separate P5 server and mount HA A/V FS ddp volume via iSCSI/A/V FS.

AD, OD user names can be imported and be kept synchronized. Authentication is via AD or OD. Access rights and other attributes for these users are created and managed in A/V FS.

Does HA A/V FS supports other protocols then iSCSI / A/V FS?

Flowingweb — Thu, 22 Oct 2020 11:37:13 +0000

HA A/V FS runs on Linux and also supports SMBI, FC and NVME-oF/RDMA. It includes the standard up to date Linux SMB server, which internally in the Dual DDP Head is connected via iSCSI. When SMB is used both data and metadata is routed via the Dual DDP Head while iSCSI / A/V FS , FC, NVME-oF/RDMA access the data in parallel. When using SMB scale out and transparent data failover is not supported.

How about a Cluster?

A/VF S in combination with a Dual DDP Head can be used to cluster iSCSI, FC and Infiniband storage systems although the preferred protocol is iSCSI. The systems then function as data containers managed by A/V FS.

How about HA A/V FS and Security?

Flowingweb — Thu, 22 Oct 2020 11:36:43 +0000

HTTPS and two-factor authentication can be used for logon. A/V FS file system remains in the DDP separate from the data and is never exposed to desktops. Operators only get to see a representation required for the Folder Volume mounted. A/V FS and iSCSI can be physically separated using different network ports and subnets. Also hardware based hard disk encryption can be used when proper hard disks are used. A/V FS is ISO 27001 and MPAA compliant. Auditing information is assembled during operation and does not need to be generated afterwards.

How about HA DDP for Play out?

Flowingweb — Thu, 22 Oct 2020 11:36:21 +0000

The play out should always go on. Therefore it is best to play out from SSD cache and cache material needed for play out using pinned so that it is available in time in the cache.

How about HA DDP for Ingest?

Flowingweb — Thu, 22 Oct 2020 11:36:11 +0000

Ingest should continue uninterrupted no matter what with the media securely stored. Possible interruption can come from hard and software and hard disks issues. HA DDP assures that when there is hard or software failure ingest during a fail over continuous without hick up. In addition a Data Location can be optionally kept aside which can be used when one of the disks within a Data Location becomes too slow.
