Vbrick currently supports a variety of shelf and rack-mount models. See the latest DME
Release Notes for a detailed description of DME models and specifications. There are no
absolute rules for sizing a multipurpose device like the DME but there are some basic
guidelines that can help you select the right model.
The smaller Model 7530 does not offer redundant power supplies or redundant VOD storage
so if these attributes are important, you should consider the larger models. The Model 7530 is
shelf-mount only while the larger models are rack mount 1U and 2U servers. Users seeking
significant VOD content playback should consider one of the two larger models.
The RAID arrays built into the Models 7550 and 7570 (seen below) are much more powerful
and better suited for frequent requests than for concurrent VOD playback. The single drive
on the Model 7530 is well suited for small to medium offices that have occasional VOD
demands.
