Wavestore HyperRAID technology offers N+5 hard drive redundancy

The resilience offered by the proprietary HyperRAID technology suite recently introduced by Wavestore, means that the risk of data loss due to hard drive failure when using their VMS can be significantly reduced.

HyperRAID provides a higher level of redundancy and employs Host Bus Adaptors cards to provide peace of mind in applications where the safe storage of data and video evidence is crucial; whether fully integrated large scale solutions or equally critical in smaller projects.

N+2 redundancy as standard

HyperRAID is capable of providing RAID5 (N+1) or RAID6 (N+2) redundancy and designed to store data across multiple drives in an array. This means that if one or even two of the drives should fail, data will continue to be recorded and safely stored. Importantly, the data that is already stored on the array even if one or two drives fail, can still be read; ensuring that vital video evidence can be retrieved.

HyperRAID Plus offers up to N+5 redundancy 

For larger arrays, HyperRAID Plus writes data across the drives in such a way that up to five of them can fail and yet recording will continue and all the recorded video footage remains available for playback. This delivers a storage solution where the danger of data being lost because of drive failure is for all intents and purposes, non-existent. 

Simplicity of setting up

Not all RAID solutions are able to offer the same level of redundancy and in this respect, HyperRAID stands out, because it does not require any specialist knowledge to set up and manage HyperRAID arrays do not need to be controlled by a RAID card. Instead a Host Bus Adaptor (HBA) is used within the recording server/NVR, which is a far more cost-effective component and enables HyperRAID to perform much faster than traditional RAID methods.

Hot-swappable drives 

Users can be alerted by email if there is a problem with one of the drives, whilst to further enhance the level of redundancy, the HyperRAID technology suite also provides the ability to include hot-swappable drives in the server. These can be installed ready to automatically take over from any drive that has failed, in order to keep the full array intact. The new drive, which is automatically brought into the array by the drive monitoring software without disruption to the ongoing storage of data, is automatically designated as a replacement for the failed drive in the array. 

Wavestore LASS

Wavestore’s unique Large Allocation Storage System (LASS) file system can control exactly where data is written to and does not need to rely on RAID card technology to perform this function. In addition, another key benefit of LASS is that it arranges for data to be stored sequentially on each of the individual drives in the array, which reduces the wear and tear on the drives compared to conventional file systems when they are required to write and read data. 

EcoStore

HyperRAID is supported by Wavestore’s EcoStore hard drive spin-down technology which delivers substantial real-world savings on the total cost of ownership of a video surveillance solution. EcoStore can automatically spin down hard drives and HyperRAID arrays which are not in a read or write state. Over 80% energy can be saved using EcoStore by spinning down drives. Associated cost savings are also achievable, such as reductions in air conditioning requirements and by limiting the wear and tear on disks that are always being powered on and spinning.
