Complete setup fast thanks to simple navigation windows
With M500 Disk Array, NEC has simplified the setup procedure, reducing the number of steps and items to be entered during initial setup. Just select the desired capacity and RAID level, and let M300 Disk Array perform its own settings to enable the best performance. And thanks to the preinstalled management software, you can have your new storage device up and running in a matter of minutes.
Storage management and data handling easy to use
The highly visual Web browser screens let you quickly grasp the status of each system component, including the storage capacity, disk load, and status of the connected servers. Easy-to-understand navigation windows allow you to make changes to the replication settings or capacity, as well as guide you through fault handling in the event of a failure. The M500 Disk Array GUI can be navigated with confidence, even by first-time users.
An advanced power-saving design that slashes power consumption
With M500 Disk Array, NEC has used its state-of-the-art low power technologies to produce a storage device that slashes previous power consumption levels to achieve one of the best power ratings in the industry. M500 Disk Array uses a power-efficient processor with a TDP (thermal design power) of 30 W and autonomously controls the operating mode to reduce the power consumption of the entire system. Low-power components such as a highly efficient power supply have been used to the greatest extent possible, and unnecessary components have been eliminated to reduce power consumption still further. M500 Disk Array also operates in environments with temperatures of up to 40°C(104°F), reducing air-conditioning energy use.
Ramp up capacity and performance just by adding hard disk drives
In today’s environment of rapid changes, you need a storage solution that responds quickly and flexibly to sudden fluctuations in data volumes. M500 Disk Array offers a newly developed Advanced Dynamic Pool technology that revolutionizes the conventional virtual pool concept. If capacity runs short, you can increase pool capacity simply by adding hard disk drives—M500 Disk Array will automatically organize the data into the optimal configuration to raise the performance of the entire data pool.
A data backup system that does not affect online operations
Having to stop your business volume every day to back up data is highly inefficient. M500 Disk Array provides a snapshot function to save only the data sections that have changed (update differences) and a function to completely replicate (copy) an entire data volume without disrupting operations. The replicated volume can then be used for tape backup or batch processing, or to evaluate applications using the actual data.
Thin provisioning for an easy distribution in a virtual environment
M500 Disk Array lets you allocate the capacity of physical volumes to virtual drives and add hard disk drives to increase capacity if shortages occur. In this way, differences between the capacity being used and the capacity of the physical volumes can be minimized, improving utilization, reducing initial investment layout, and lowering power consumption. Hard disk drives can also be added without disrupting operations, eliminating the need for inefficient stoppages and schedule adjustments.
