Data loss is inevitable for any data storage device, yet while companies work to minimise this possibility as much as possible, it cannot be completely resolved
However, it is important to know that the security of the storage itself is not simply based on its system or hardware, but also on which network it is installed.
Because if the network is vulnerable, it will be the storages and servers that are on the network.
For this reason it is necessary to put a Pfsense Firewall or some other type of professional security system, to make malicious attacks more difficult.
It also validates the security of local machines, preventing access by hackers.
Storages are unique systems for data storage. It can serve as an extension of the storage capacity of servers, but can also be used independently.
HP has a Storage line, which is called EVA (Enterprise Virtual Array).
EVA Line
The EVA Line is a high performance line that features the “virtual” RAID storage system.
The EVA Line can store high amounts of data, and has an option for the user to transfer data quickly and securely.
The challenge for any company producing Storages is to minimise the chances of data loss. Even if those chances are never completely cancelled out.
Data loss is a real risk for any business.
The EVA range has several configurations available, each set up to optimise its use.
