Storage Solutions




The DS Media Servers core networking architecture is designed to scale from a single server with local media storage to multiple ingest and playout servers with central NAS/SAN storage, while supporting remote high-resolution and low-resolution editor and browser clients.

This design provides the ability for any DS Media Servers playout server or other NewsFlow client to become completely autonomous in the advent of a critical failure of the central database or central media storage. In case of a network failure, all assets scheduled for broadcast are cached on the local playout machines and will still be available for playout.

Shared Area Networks

The delaStream Solutions SAN Fibre-Channel architecture supports up to 90 concurrent high-resolution SD streams and 22 HD streams, which can be shared between any combination of ingest/playout server channels or NLEs.

Network Attached Storage

DS's scalable next-generation NAS architecture provides a price and functional range to suit every budget and project size. Available systems support bandwidth throughput up to 1 Gigabyte/second, providing cost-effective solutions for HD media infrastructures. Individual chassis can hold up to 36TB of storage.


DAS STORAGE

Direct Attached Storage (DAS) is storage that is directly attached to an DS Media Servers using a dedicated data connection such as SCSI or Fiber Channel.

DAS provides additional local storage capacity and fast disk access because of the dedicated data connection. This type of storage is typically used with standalone DS Media Servers installations. DS Media Servers are certified with DAS providers such as Rorke-Data, Ciprico, Data Direct Networks, and other leading vendors.


NAS STORAGE

DS Storage Networks: The DS Media Servers core networking architecture is designed to scale from a single server with local media storage to multiple ingest and playout servers with central NAS/SAN storage while supporting remote high resolution and low resolution editor and browser clients. This design provides the ability for any DS Media Servers playout server or other NewsFlow client to become completely autonomous in the advent of a critical failure of the central database or central media storage. In case of a network failure, all assets scheduled for broadcast are cached on the local playout machines and therefore will still be available for playout.

Network Attached Storage: Networked Attached Storage (NAS) is shared storage on a local area network. A NAS server is a storage appliance that consists of a high performance file server that plugs into a Local Area Network (LAN). This solution is specialized for optimized file storing, retrieving, and serving files. Users running different types of machines and running different types of operating systems can share files, and DS tracks media assets across unlimited Media Locations.

DS NAS 3000/6000 series: The DS NAS 3000/6000 series enterprise-class unified network storage systems can scale up to 36TB, or 2700 hours of 25 Mb/s video per chassis. The DS NAS 6000 series provides bandwidth throughput up to 1 Gigabyte/second, providing cost-effective solutions for HD media infrastructures. Multiple Ethernet ports, RAID-5ES protection, live file system replication, and feature-packed software management tools on a Linux-based operating system create a truly best-of-class storage solution.

DS NAS 2000 series: The ultra-affordable DS NAS 2000 series for smaller applications supports 800 Mb/s throughput, or 25 concurrent 25Mb/s streams, and scales from 3.2 to 24TB in chassis sizes from 2U to 4U. It runs on an end-to-end 64-bit Linux-based storage computing platform driven by dual or dual-core CPUs with RAID-5 or -6 protection. System status warnings and disk failure predictions are delivered via email and/or page notification.


SAN STORAGE

This design provides the ability for any DS Media Servers playout server or other NewsFlow client to become completely autonomous in the advent of a critical failure of the central database or central media storage. In case of a network failure, all assets scheduled for broadcast are cached on the local playout machines and therefore will still be available for playout.

Network Attached Storage: Storage Area Networks (SAN) is a dedicated network that connects storage devices with servers. SANs are typically back end storage networks that are separate from LANs. SANs can be geographically distributed up to 6 miles and operate at gigabit speeds. SANs provide a block level interface while NAS servers provide a file-level interface. SANs are good for large infrastructures with many high-bandwidth video servers and nonlinear editors. SANs are appropriate for data transfer intensive applications and for storing large amounts of data.

DS SAN-3000: The delaStream Solutions SAN Fibre-Channel architecture supports up to 200 concurrent high-resolution SD streams and 22 HD streams, which can be shared between any combination of ingest/playout server channels or NLEs. However, additional SAN appliances can be added making the DS Media Servers almost infinitely scalable.


ARCHIVE SOLUTION

Archiving to Fit Your Needs: DS Media Servers offer asset protection with user profiles, user group settings, and storage quotas which set recording parameters and manage disk space. DS Media Servers come standard with an Export to Folder function and seamless support for the Atempo Time Navigator middleware product for small or large nearline and archive solutions utilizing LTO technology.

End-to-End Solution: The DS Media Archive Library (VT-MAL) features Qualstar's BQ20/44, which combines a high performance server with proven RLS-Series robotic tape libraries. The VT-MAL archives 3,283 hours of 25 Mb/sec MPEG-2 content for automated retrieval in just 7U of rack space in your control room.

Hardware Overview: Content is stored on a combination of hard disk and digital data tapes, and shelved tapes can still be managed through the DS Media Archive Library. All tapes are controlled by barcode, making retrieval from the shelf fast and easy.

The VT-MAL is fully engineered for continuous operation, incorporating 3TB of raw hard disk with RAID (0,1,5) configurations and the latest dual-core CPU technology running Windows 2008 Server Edition.

This highly scalable archive solution starts out with 20 cartridge slots and id upgradable to 44 slots, storing 1,440 hours of DV25 near-line in addition to 210 hours on hard disk.

All tapes are stored in removable magazines. Each magazine holds four LTO-4 tape cartridges storing 288 hours of video at 25Mb/sec. The barcodes for each tape can be viewed through a clear plastic cover to enable rapid selection of a video clip that is to be restored from the shelf.

Start out with a single high performance IBM LTO tape drive and add a second as throughput demands increase. A second LTO drive allows simultaneous reads and writes which greatly improves performance. This system is so simple to install and operate that you can expand it yourself as your needs grow, lessening your initial outlay and reducing operating costs.

INTERNAL STORAGE

Internal Storage Drives: DS Media Servers standard-definition media servers include at least 750GB of internal storage, or 60 hours of media storage at 25 Mb/s. DS Media Servers high-definition media servers come standard with 8TB of internal storage, or 560 hours at 50 Mb/s. All DS Media Servers systems are upgradeable to 16TB of internal storage utilizing 8x 2TB drives. systems utilize an eight-slot, front loading, SATA drive bay. In a shared networked environment, the internal storage caches the media files and database locally increasing overall system reliability.

Local Database Caching: The DS networking architecture is designed so that every DS Media Servers caches the Database information locally. On startup, the DS Media Servers connects to the DSDB and caches all the database information including media locations and metadata. Upon addition, deletion or modification of media to the DSDB, each DS Media Servers receives a notification and immediately updates the local server's cache. Other client applications like DS Proxy Editor, DS Director and enVue work in the same fashion. DS Media Servers playback is achieved by reading the database from the local cache. In the event that the DS Media Servers loses its connection with the DS Database, playback continues from the local cache.
