Looking to build a high performance NAS storage? The gateway to success would be using a high-speed network at the core of the system. Let’s round up the key elements we need to consider when designing the optimal network infrastructure.

In a recent article, Jim O'Reilly defined eight key milestones in the data storage industry. Jim’s list included SCSI-based Interfaces, Drive Capacity, RAID and SAN, NAS, SSD, NVMe, Software-defined Storage and the Cloud. While all these factors are, indeed, relevant as ever, they all belong in the present. In an attempt of technology fortune-telling, I’d be interested to muse on The Next Big Thing that the future of data storage holds for us.

Network Attached Storage (NAS) allows enterprises of any size to consolidate distributed file servers into a smaller number of specialized storage systems. These systems provide access to files through several standard access protocols, such as NFS, SMB, FTP, etc. and have a centralized management console.

Performance measurement Processing high-definition video implies uninterrupted multi-thread access to big volumes of media data. The video editing performance and time-to-market depend heavily on data storage characteristics. It’s not easy to assess data storage system characteristics outside the working environment, workstations and actual applications. However, synthetic tests help to compare different connection types and see […]

The original article was provided by the Entry Team. Media & Entertainment is an epitome of a market that actively embraces software-defined storage. Classic data storage systems are no longer the optimal choice when it comes to high-performance processing of big volumes of sequential data. Software-defined storage changes the industry landscape and approaches, catering to […]

RAID storage can be configured in multiple ways. These configurations, defining how data is dispersed among multiple disks are called RAID levels. Different RAID levels exhibit different performance and reliability. The most common schemes are reviewed below.

Silent Data Corruption is the worst type of disk error. These errors are caused by bugs in drivers and disk firmware, memory errors, drive-head crashes, as well as similar software and hardware problems. Silent errors that occur during the write to disk process are the most dangerous, as there is no indication that the data is incorrect.

Reading large data blocks from RAID storage appliances, normally requires that disk array reads from each drive, combines fragments and passes on to the external interface such as FC, iSCSI, IB or SAS. Each drive in the array has a difference speed, and even same model disks have slightly difference response times. Plus, seek time might differ depending on where the heads were on each disk in the array before the read request came in. Therefore, drives will complete the read request at different points in time.
