Opslag D2-4QI-24 iSCSI RAID system is designed for high availability (HA) applications.
The D2-4QI-24 is equipped with redundant components for each major function, including
redundant RAID controllers, three power supplies, redundant fan modules, redundant
battery backup modules, and etc. It is for non-stop service requirements. The optimized
IOPS and throughput are capable for run-time critical online services, such as SQL,
Exchange, and high-end surveillance storages. With the iSCSI interface, D2-4QI-24
is ideal for virtualization environments - VMware, Hyper-V, and Citrix. User can
also install up to 32 OSes in the iSCSI RAID system through Boot-from-SAN. With
this feature, the multiple OSes/Servers can be managed easily and highly protected
by Opslag writeable snapshot, and no system downtime from single point of failure.
The other applications not mentioned here are not limited. Pease contact us for
more information.
