This is possible because, by default, HCI solutions take care of moving data within our SDS based on algorithms that detect what data virtual machines most frequently access. This gives us the possibility to increase I/O for applications with high traffic volume. This translates into an increase in the overall performance of our infrastructure by preventing data from having to travel over a network to be manipulated.Īnother characteristic element of HCI solutions is the presence of one or more solid-state disks (SSDs), combined with conventional high capacity hard disks (hybrid HCIs) or only SSDs (All-flash HCIs). It is also important to note that this data store is made up of the storage provided by the disks, which are directly connected to each of the nodes and, therefore, there is no need for a centralized storage solution such as a SAN or NAS. This is where our hyperconvergent solution will begin to display its features, taking all the disks present in each node to create a centralized data store. These nodes are the ones that will provide our cluster with processing, network, storage and memory capabilities.Īmong the highlights of HCI solutions is Software Defined Storage (SDS). In other words, both are infrastructure solutions (HCI), which integrate processing, memory, network and storage in the same container or cluster.Ī common feature among HCI solutions is the presence of multiple nodes in the same container. Let’s keep in mind that the objective of both solutions is to face the deficiencies of the traditional architecture, increasing the efficiency of the available resources, simplifying the management processes by means of pre-configured solutions, which do not require a network storage infrastructure. This invites us to evaluate the best hyperconvergent solutions and to discuss between Nutanix VS VMware. However, while such solutions offer the possibility of containing more than ten servers where there would usually be four, they still rely on external centralized storage solutions for their operation, which translates into additional devices, cabling and labour.Īs we mentioned earlier regarding the evolutionary process of IT solutions, it was expected that, eventually, a single device or appliance would have the capacity to contain all the key elements of a CPD infrastructure. If we look back at past technologies, it will be evident how this process of convergence has been raised and a good reference of this is HP BladeSystem, one of the most innovative proposals of 2004 in terms of IT infrastructure. Of course, this is not going to be the exception. The fact that new hardware or software is becoming a global trend is not something that happens overnight. You must have noticed that hyper convergence is a worldwide trend including large hardware vendors such as DELL, HP, and IBM, to name a few, as well as the software solutions that make it possible. It also delivers management, backup, migration, deduplication, compression, restoration, and single pane of glass solutions for monitoring our hyper convergent solution (HCI). Tier 3, an appliance that not only integrates network, processing and storage elements.Tier 2, integrates all these elements into a single appliance.Tier 1, for solutions where, by opening our rack door, we can visually differentiate network, processing and storage elements.We can divide the concept of convergence into three levels:
