块、文件、对象：什么适合您的应用程序？

还记得那时生活很简单，只需选择NAS或SAN吗？现在，存储管理员有许多存储格式选项可供选择，如块、对象、文件和NAS，如果您前往我们在AWS的朋友那里，他们还会添加一些首字母缩写选项。在选择最能满足您的数据和工作流需求的格式时做出正确的选择可能会令人困惑，但正确选择格式对您的组织的整体成功至关重要。糟糕的选择可能导致数据和应用程序服务延迟、成本过高、缺乏可伸缩性、管理框架复杂以及一系列其他问题。因此，让我们深入研究其中的一些格式，以及它们最适合的工作流。

Block Storage

First stop is good ole块存储器. It is when a raw volume of data storage is presented to a server, usually from a storage attached network (SAN) accessed via FC, SAS, or iSCSI. Each volume block can function as an individual hard drive; think of a USB drive you plug into your laptop, it is simply a mounted storage volume to be used by a file system or a database. Block storage is ones and zeros; there is no file system or metadata for tracking and visualizing data; the operating system must handle all the read/write of the blocks. The benefits of this option are throughput performance, low latency, and high IOPS. Typically, block is best suited in support of virtual infrastructure (hypervisors) and databases, given its tendency to be high performing. Though block is very versatile, its lack of metadata describing your data and ability to manage storage allocations on a file level, makes it less suited for workflows that are file centric.

File Storage

That is a nice segue to file-based storage. Unlike block storage,基于文件的存储(NAS, File System, Object) hide much of the complexity associated with block storage. The NAS simply appears as a drive letter on the network, and as the name suggests, does well at storing and managing files, whereas block storage lacks that higher-level organization of data and makes it more challenging. File-based storage is common in home directories and mainstream IT file shares due to its ability to easily share files across the network, as well as the ability to scale. File-based storage is also gaining popularity within more data-intensive workflows, such as seen in M&E, Oil & Gas, and research applications. This is mostly due to the need to access data as files rather than blocks or ones and zeros. It also helps that file-based storage has moved away from costly Fibre Channel to high-performing, lower-cost 100Gbe network. It also helps that scalability, shareability, and the overall TCO structure of file-based storage makes it attractive in file-centric workflows.

不过，这家新成立的公司正在为文件存储提供资金支持，非常适合我们现在所处的数据密集型物联网新世界。由AWS S3和Glacier推广，亚搏电竞app下载is quickly becoming a de facto standard for storing massive amounts of unstructured data found in data science applications, web farms storing massive troves of music or photos, and AI/ML data repositories for workflows for genomic research to autonomous vehicles. So, what makes object so cool? First off, it is a simple concept where data is delivered as objects that have rich, searchable metadata and a unique ID number. Unlike file storage where you organize your files in directories and trees, objects are placed into massive scale, flat, highly durable, and available buckets or pools that can be on prem, in the cloud, or distributed across all of the above. That metadata in each object is a crucial key as it gives the applications and users the ability to quickly search and run analytics against very large unstructured data repositories. This is one reason its popular in machine learning and anything leveraging advanced analytics. Object storage also is inherently very secure – by using erasure coding, it provides very high levels of data durability, often exceeding 10-15 9’s. Meaning, once an object is created it is likely to be there forever. This makes object storage ideal for backup or archive where data preservation is a critical component. Finally, with object storage, your CFO will appreciate all this technical jargon given object storage is one of the lowest-cost storage solutions you can deploy aside from ever lovable magnetic media tape storage, of course.

Which Storage Format Meets Your Needs?

正如您在下面的图表和上面的段落中所看到的，部署存储有很多种方法，每种方法对于不同的用例都有独特的好处。需要数据库等结构化应用程序的性能吗？考虑阻塞。大量用户共享文件；NAS可能是合适的。为癌症研究或未来的飞行汽车建立数据仓库？对象存储很可能是我们要走的道路。并非所有的存储都是平等创建的，您的数据中心很可能需要多种解决方案来满足您公司的需要。在Quantum，我们的技术存储专家希望帮助您做出最适合您公司任务需要的明智决策。我们希望这个博客提供一些好的见解和信息，在接下来的文章中，我们将解决数据管理的困境。亚搏电竞app下载亚搏官网app登录入口
