With no spinning platters or sweeping actuator arms in flash-based arrays, there's almost no heat generated and very little noise from devices that use flash storage. More important is the raw speed, reliability and now, durability of all-flash storage.
Oracle, SQL and many other databases benefit from the massive improvement in performance as SSDs are well known in the IT industry as the single best upgrade to boost performance, to reduce noise, to reduce power consumption, and to reduce heat generation. Our selection of storage vendors exemplify these benefits and attributes in abundance.
Hybrid flash arrays, use a mix of flash storage (SSD and NAND Flash) and spinning disk for primary storage, with the "hottest" or most-likely-to-be-accessed data stored on flash media and data less likely to be needed immediately on spinning disk. With hybrid arrays, vendors typically include software that automatically migrates data between the flash and the spinning disk tiers based on anticipated or recent access.
Hybrid arrays are not the same as more traditional disk-based arrays with flash-based cache. In hybrid arrays, the total capacity is considered primary storage, whereas on disk arrays with flash-based cache the flash is used for temporary fast reads or writes with the actual storage of the data held on the hard drives.
Traditional storage is generally broken up into Primary and Secondary storage. Primary storage includes storage area networks (SAN), direct-attached disks (DAS) and network-attached storage (NAS).
Primary storage is generally accessed on a random basis, and it acts as support for active applications. Secondary storage is your backup storage, designed to protect your data. There is still a place for traditional storage solutions especially in the areas backup and disaster recovery and even where cost is the main driver.
Put simply, software defined storage solutions aim to manage and automate storage requirements by intelligent software as opposed to the storage hardware and associated software. In this way, the pooled storage infrastructure resources in a software-defined storage (SDS) environment can be automatically and efficiently allocated to match the application needs of an enterprise. By separating the storage hardware from the software that manages the storage infrastructure, software-defined storage enables enterprises to purchase heterogeneous storage hardware without having to worry as much about issues such as interoperability, under- or over-utilization of specific storage resources, and manual oversight of storage resources.
The software that enables a software-defined storage environment can provide functionality such as deduplication, replication, thin provisioning, snapshots and other backup and restore capabilities across a wide range of server hardware components. The key benefits of software-defined storage over traditional storage can be increased flexibility, automated management and cost efficiency.
Backup is simply having a reliable copy of important files held somewhere safe. Backups can be performed locally, remotely or both. However with the enormous leaps forward in technologies, Epaton work with innovative solutions to make these functions far simpler to manage and faster to perform. Disaster Recovery is more than just data backup, it ensures that you have the resources available to get your systems back up and running within certain timeframes given predefined scenarios.
If required, Disaster Recovery techniques facilitate rebuilding essential systems such as servers in the minimum of time, with users, files and installed software just as they were before the failure. Disaster Recovery is a vital component of Business Continuity Planning, which is taking the proper measures to plan for a critical event, so that you can continue to operate with the minimum of disruption.
What is a "converged infrastructure"?
Sometimes known as integrated systems or unified computing, converged infrastructure operates by grouping multiple information technology (IT) components into a single, optimized computing package. Components of a converged infrastructure may include servers, data storage devices, networking equipment and software for IT infrastructure management, automation and orchestration.
What does this really mean?
A converged infrastructure essentially turns disparate datacentre components into a single appliance that can be centrally managed. The goal of a converged infrastructure is to minimize compatibility issues and simplify the management of servers, storage systems and network devices while reducing costs for cabling, cooling, power and floor space.
What’s the difference between a converged and hyper-converged infrastructure?
As the converged infrastructure market continues to develop and grow, some vendors are differentiating their products by bundling virtualization software with their converged infrastructure offerings (usually with VMware and Hyper-V). Such an approach is sometimes marketed as being a "hyper-converged infrastructure" solution. (The prefix "hyper" refers to the hypervisor in the virtualization layer.) Vendors may also provide additional functionality for cloud bursting or disaster recovery, providing administrators with the ability to completely manage both physical and virtual infrastructures in a federated manner.
