Holographic Grid Cloud, a Futurable High Storage Technology for the Next Generation Astronomical Facilities

In the immediate future holographic technology will be available to store a very large amount of data in HVD (Holographic Versatile Disk) devices. This technology make extensive use of the WORM (Write-Once-Read-Many) paradigm: this means that such devices allow for a simultaneous and parallel reading of millions of volumetric pixels (i.e. voxels). This characteristic will make accessible wherever the acquired data from a telescope (or satellite) in a quite-simultaneous way. With the support of this new technology the aim of this paper is to identify the guidelines for the implementation of a distributed RAID system, a sort of "Storage block" to distribute astronomical data over different geographical sites acting as a single remote device.
