Tape based archive solution
To most effective Active archive BIG DATA storage solution

For the past 2 decades, block and file have been the two mayor external shared storage system protocols. These two protocols have been successful due to the ubiquity of the networking interfaces that drive them. In the case of block devices, that has been and Ethernet (iSCSI )Fibre Channel; and for file storage, it has been Ethernet (CIFS/SMB and NFS).

Mainly due to issues with data protection and indexing and addressing, block and file are not first choice for building large-scale data repositories,. RAID doesn’t scale adequately and file-based protocols start to run into issues with metadata management at large-sized volumes(petabytes) of data and millions to billions of files.

Ameliorated data management

Within all storage systems, there is always the risk of data loss or  data corruption. The most disk and solid-state storage media are reliable nowadays , but not really error-free. This will be causing problems with very large-scale data repositories. Storage media does fail and may be subject to silent corruption or unrecoverable read errors  that put your data at risk.

Object Storage

is a storage architecture that manages data as objects, as opposed to other storage architectures like file systems which manage data as a file hierarchy and block storage which manages data as blocks within sectors and tracks. Object storage stores mitigate these problems using data scrubbing techniques that validate and rebuild (self-healing retention) potentially corrupt or missing data. Object storage also allows the addressing and identification of individual objects by more than just file name and file path. Object storage adds a unique identifier within a container , or across the entire system, to support much larger namespaces and eliminate name collisions. The use of erasure coding and the typical write-once nature of object store data allows failed data to be recreated as a background task with little or no impact to production operations.

Simplified data access . How does it work?

In the centre of the technology, object stores use vastly simplified access methods to store and retrieve data. REST APIs based on Web-based protocols like HTTP allow objects to be accessed through a unique URL. The URL is built from API commands like GET and PUT plus a unique reference code assigned to each object. this is  the object ID.

Cost-effective cloud storage is now the status quo, but the inherent liability associated with running network operations from an off-site server means that companies will likely prefer a mixed storage strategy over limiting their investments to a single technology.

 

Facts

HTTP has demonstrated its value in storage as a transport protocol

S3 has emerged as the de-facto market standard, Amazon has acted as the enabler for object storage.

Tape storage offers Lower cost per GB

How can tape and disc or flash cooperate?

Tapes are as reliable if not more reliable than disk, and they last longer. We know  that tapes spend most time offline and so don’t consume power in such a state. An effective TCO is covered by the use of a tape archive. Many petabytes will find a safe archive storage location at tape.

Disc and Flash:

Now you know your archive data is safe and stored we have to talk about  data discovery, predictive analytics, text meta data and  data mining. With the use of analytics solutions comes a much better  decisioning in order to  deliver more  successful business results. Within your big archive data are your family jewels faulted so be careful . Complex metadata and analyse platforms, and exponential data growth is asking for a different approach. Use the think capacity of disc or flash solutions on top of your tape faults you will use the best of both worlds.

So tape is the only viable place for object storage. This opens the door to massively scalable object stores comprising billions of graphical images and other big data. (LTFS) presents a tape library as a NAS share, enabling users to leverage familiar file system tools, and even drag and drop files directly to and from a tape cartridge, just like a USB or disk-based NAS share.
