SAN storage
NEC D8 Storage
The D8 SAN Storage array brings
an innovative architecture to
the mid-range that provides
tremendous flexibility, resiliency,
and scalability. The family of
D-Series arrays including D3,
D3i, D4, and D8 models is used for iSCSI and Fibre Channel SANs
for primary storage, high capacity secondary storage, or both in a
tiered storage hierarchy.
Hot-swappable disk ports, cache, and host ports modules
The D8 has a “nodal” architecture that is built around controller
nodes. Up to four nodes join to create one or more virtual arrays
and provide resiliency that delivers non-stop performance despite
the failure of a node (or even multiple nodes). As you add nodes the
potential bandwidth, performance, and capacity also increase.
Benefits
Dependable
Nodal and modular redundancy superior to
traditional ‘active-active’ controller architecture
Scalable
Non-disruptive growth from 3 to 1,536 drives, from
4 GB cache to 128 GB, and from 8 FC ports to 64.
Data-in-place conversion from the NEC D3 to a D8
Efficient
Adjust cache, storage, and port scalability to meet
changing needs
The D8 splits up the functionality of a “traditional” array controller
into separate modules that are hot-swappable and fully redundant
within each node. While the Fibre Channel host connections and
the connections to the disk enclosures are fully redundant, the
data cache and power can survive even multiple failures!
Besides having resiliency higher than traditional architectures,
each node can expand online to include additional modules. As
time goes by and application needs change, the array performance,
bandwidth, and capacity can be adjusted for new purposes and
new applications: Over 65,000 D8 system module configurations
are supported, so the array can transform to meet changing needs
instead of requiring the purchase and migration to a new array with
different characteristics.
