All hardware models use highest quality enterprise and datacenter grade hardware, including ECC RAM, Intel server network adapters, and 24/7 enterprise/datacenter harddisks. All disks are hot-swappable.

The performance numbers are realistic figures based on experience with real customer scenarios. These performance numbers have also been verified in our internal performance test lab.

Recommendations

MARA Systems currently offers five hardware models that differ by the form factor, performance and storage capacity. Customers can combine several of these hardware appliances (even different models with different performance) to create a scalable cache cluster/grid. The special CacheMARA approach allows the disks to be shared among all nodes in the cluster. This means that a CacheMARA can access every object on any disk of the cluster, independend if the disk is locally in the same CacheMARA or in some other CacheMARA of the cluster. Also CacheMARA avoids duplicated ojects in the cluster and makes sure that the total cluster cache space is approximately the sum of the individual total cache spaces.

Example: 5 x model XXL-6000/72 deliver a total cluster caching capacity of 360 TB. As a result there is a shared total caching space of 360 TB and every CacheMARA can access and deliver objects from any disk in the cluster.
