Network-attached storage

Network-attached storage
Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role.[nb 1] As of 2010[update] NAS devices are gaining popularity, as a convenient method of sharing files among multiple computers.[1] Potential benefits of network-attached storage, compared to file servers, include faster data access, easier administration, and simple configuration.[2] Note that hard drives with "NAS" in their name are functionally the same as other drives.

Tape Backup vs Hard Disk Backup: What Does the Future Hold? I was frequenting Spiceworks earlier today and came across a post asking if “tape was legacy”. I think what they were asking is whether backup to tape is the kind of legacy technology today that we see with VHS—there are still a few out there but the technology is on its way out. I realize that there are still advantages with tape when it comes to large volume backups and the ability to physically move the backup media to an offsite location. But even with these advantages it seems that backups to disk (and dare I say to the cloud?) have so many more advantages. Let’s do a quick comparison of tape and disk storage to consider the advantages of each: Capacity “As of 2011, the highest capacity tape cartridges (T10000C) can store 5 TB of uncompressed data” (source Wikipedia), while hard drives have followed Kryder’s law (much like Moore’s law) and doubled areal density every two to four years putting disk drive capacity currently somewhere around 4 TB. Speed Cost Ok, so there you have it.

NAS Advantages: A VARs View - Infostor NAS Advantages: A VAR`s View Potential benefits of network-attached storage (NAS) include faster data access, easier administration, and no-brainer configuration. Ron Levine Don Schrenk, a storage consultant with Direct Connect Systems, a value-added reseller in Marietta, GA, has specialized in providing network storage solutions to Fortune 1000 clients for more than four years. InfoStor recently talked with Schrenk to get his thoughts about the advantages of NAS and how it can be implemented in a range of environments. Why is NAS gaining popularity? Network administrators are always on the lookout for dependable, expandable, and easy-to-install options to alleviate server storage overload. On a network, data-access time determines how rapidly you can do your job. What are some of the factors to consider before implementing NAS? The first thing you look at is how many users you have on the system. When is NAS not a good idea? What makes NAS devices so easy to install? How do you get it going?

Tape backup VS disk backup. The best tape backup software - EaseUS Todo Backup Server New trends in storage now make it easier than ever for companies to expand their data capacity. However, many companies continue to rely on tape backup as the primary media for backing up their data. When talking about backup storage people always think in terms of scalability of performance, reliability, security, and usability issues. The basics of backup management haven't changed much over the past year, but new products and technologies have made it easier to address these issues, making extreme scalability in disk-based data backup much more feasible and desirable than the traditional tape backup. Comparing in speed - As a primary target for backup, disk has quickly become accepted as the optimal media. Comparing in costs - Disk-based backups don't suffer from the same incremental restore penalties experienced by tape drives. Disk versus tape technology Understanding the facts First, tape can be removed. Disk-based Backups Major advantages of disk technology Faster restores

What is NAS? How backup NAS storage data and how to backup data to NAS? NAS (Network-attached storage) is file-level computer data storage connected to a computer network providing data access to heterogeneous clients.

Storage Optimization Techniques: Review the Benefits of Thin Provisioning Introduction For several years Wikibon has been studying the benefits of virtualization and thin provisioning. Our research spans dozens of detailed customer interviews and studies of many hundreds of customers over several thousand storage volumes. As well, our information has been validated through Wikibon's Energy Lab, which produces studies designed to assist customers in understanding the degree to which a product contributes to energy efficiency. Our objectives in conducting efficiency analyses are to identify not only the hardware impacts on issues related to utilization and energy consumption but more importantly the hard-to-quantify green software aspects of technologies. Wikibon Energy Lab Validation Reports are submitted to utilities such as Pacific Gas & Electric Company as part of an energy incentive qualification process where often outside engineering firms have validated our findings.

Backup master class: Let’s get NASty Thus far, our backup series has been primarily concerned with software and online solutions. Now we’re turning our attention to personal backup solutions that attach to a home network. Dubbed NAS (network attached storage), these products offer a local storage pool to the other devices on a network, without being tied directly to any single PC. DAS vs. NAS: Parsing the difference Before we launch into a discussion of our various NAS devices, we need to touch on how the storage market has evolved in the past ten years. Ten years later, the balance of power has shifted dramatically. Do you need a RAID? All three of the products we’re reviewing today are two-bay solutions that can be configured as JBOD (just a bunch of disks), RAID 0, or RAID 1. One other potential advantage is drive accessibility. The contenders We’ve got three separate solutions up for testing today: Seagate’s BlackArmor NAS 220, Western Digital’s My Book Live Duo, and Synology’s DS213+.

RAID Levels Explained If you've ever looked into purchasing a NAS device or server, particularly for a small business, you've no doubt come across the term "RAID." RAID stands for Redundant Array of Inexpensive (or sometimes "Independent") Disks. In general, a RAID-enabled system uses two or more hard disks to improve the performance or provide some level of fault tolerance for a machine—typically a NAS or server. The way in which you configure that fault tolerance depends on the RAID level you set up. RAID Overview RAID is traditionally implemented in businesses and organizations where disk fault tolerance and optimized performance are must-haves, not luxuries. Software RAID means you can setup RAID without need for a dedicated hardware RAID controller. This type of RAID is available in other operating systems as well, including OS X Server, Linux, and Windows Servers. Which RAID Is Right for Me? Here's the rundown on popular RAID levels: •RAID 0 is used to boost a server's performance.

15 Reasons to use Backup NAS vs Generic NAS Pros and Cons of DAS, Generic NAS, and Specialty NAS for Backup Network Attached Storage vs. Direct Attached Storage PDF Version Introduction Network Attached Storage (NAS) boxes are very common to add shared storage to a small business network infrastructure. Off-site Backup. Reliable Connectors. Summary: Both network and direct attached removable hard drives (NAS and DAS) can be effective for local backup and offsite storage.

VM-aware storage provides better migration, performance and more VM-aware storage is a hot topic right now in the virtualization world, according to storage and virtualization expert Stephen Foskett. In the past year there was an increase in storage developed specifically for virtual machines. These storage systems enhance data migration, performance and integration with virtual server environments. However, some VM storage products will only work well if virtual machines are the only workloads running on it, which may not benefit organizations that haven't virtualized their entire environment. How are vendors making VM-aware storage different from traditional storage, and what are some of the common features that can be found with it? Stephen Foskett: That's really a major industry trend right now. You mentioned VM-aware storage having better data movement and performance. Foskett: The number one advantage is that … virtualization breaks storage. That's especially true with small businesses.
