Lightning 9900 V Series Product Off e r i n g s
The Lightning 9900 V Series offers two models – the Lightning 9980V
™
and the
Lightning 9970V
™
. The Lightning 9980V system is recommended for users requiring large
storage capacities of 149TB+ of raw storage capacity. With the same advanced architecture
as the Lightning 9980V system, the Lightning 9970V system bridges the gap between
standard midrange and premium-priced advanced-function storage, with capacities up to
18TB+ of storage. The Lightning 9970V system is recommended for users who require
advanced function capabilities of premium storage, yet do not need the actual storage
capacity of the Lightning 9980V system. Table 1 compares key features of the two new
Lightning 9900 V Series product offerings.
Selecting the Lightning 9970V system or Lightning 9980V system depends on capacity
requirements, performance requirements, and expected growth of data. The Lightning 9900
V Series therefore offers product alternatives that cover a very broad range of scalability, as
illustrated in Figure 1.
