R&S SpycerNode uses what Rohde & Schwarz calls High Performance Computing (HPC) file system for its media server. HPC employs redundancy using software-based “RAID” technologies called erasure coding in combination with declustering to increase overall performance and reduce rebuild times.
R&S SpycerNode features Rohde & Schwarz‘s device manager web application which makes it much easier to set up and use Rohde & Schwarz solutions in an integrated fashion. Device manager helps to reduce setup times and simplifies maintenance and service due to its intuitive web-based UI operated through a single client. In developing R&S SpycerNode, Rohde & Schwarz has introduced data protection systems based on erasure coding and declustering. Erasure coding means that a data block is always written including parity.
Declustering is a part of the data protection approach of HPC setups (formerly known as RAID). It is software based and in comparison to a traditional RAID setup the spare disk is spread over all other disks and is not a dedicated disk. This will decrease rebuild times and reduce performance impact. Also, there are no limitations with the RAID controller, which results in much higher IOPS (input/output operations per second). Importantly, there is no impact on system performance over time due to declustering.
R&S SpycerNode comes in multiple 2U and 5U chassis designs, which are available with NL-SAS HDD and SAS SSDs in different capacities. An additional 2u24 chassis design is a pure flash system. There are main processor units and JBOD units. A main unit is always redundant, equipped with two appliance controllers (AP). Each AP features two 100 Gbit interfaces resulting in four 100 Gbit interfaces per main unit.
Here are all the details.
