The 3PAR StoreServ 7200 is limited to two controllers, and the 7400 series can have 2 to 4 controllers and the 10,000 series can have up to 8 Node controllers. But in 3PAR storage, you start with two controllers and you can have up to 8 Node controllers depending on the line and the number of controllers you need. When you set up an EVA storage, you will have two controllers from the beginning and it is not possible to add another controller to these two controllers. The second difference in these architectures is related to modularity.

All this activity is sent in a Passive Full Mesh Backplane that connects the controller nodes to each other and to the storage devices.Įach of the nodes is connected to each other with high-speed links, and also the RS-232 low-speed serial link is intended for reconnection, so that when the main links are disconnected, control information is transferred between the nodes. In 3PAR, all controller nodes have access to the LUN and can serve all sent requests. Any request received through other controllers is easily managed by the controller. In EVA storage, only one controller can access and control the LUN at a time.

Note that, t o activate various port functions on the HPE servers, specific HPE License types would be required. We’ve seen standard servers used to create arrays in storage controllers in cluster systems, and we’ve seen upgrades to architectures like 3PAR StoreServ arrays that have an Active-Active Mesh with up to 8 controllers to improve performance.
When we use this concept in storage, it means that we need to have more arrays to deal with the problems.īut over time, newer arrays with much different architectures have come to market, and they directly and automatically address the Bottleneck problems that we traditionally see in modular arrays. An experienced system administrator should identify these issues and fix the problem. Bottlenecks and errors that occur in the system causing interruptions are the issues that system administrators have the most problems with. 3PAR and EVA Storages DifferencesģPAR and EVA are storage devices with many similarities but with important differences. With the introduction of the 7,000 series of HP products at the end of 2012, it became increasingly clear that these products could be our future storage platform. These technologies are very similar to each other.
Important advantages of 3PAR storage are: HPE 3PAR storage devices have great capabilities, some of which we will mention in the following.
In August 2010, DELL Company made an offer to buy the company, which 7 days later HP made another offer, which resulted in HP buying the company for $ 2.35 billion, and now 3PAR products called HPE 3PAR are introduced to the market. In 2010, the company was selected by Forbes Magazine as one of the top four IT companies in the field of development. This device meets all the needs of an organization in the field of information storage and its design is based on virtualization.ģPAR was founded in 1999 in California by three hardware experts, and the name PAR is derived from their names. That’s why HPE offers 3PAR storage devices to its customers. You need to go for storage devices that are reasonably priced. Today, organizations need storage devices to be able to introduce new capabilities to their users while saving on hardware resources and additional costs. The cost of storage for your servers will certainly add to the cost of setting up a network, but there are many benefits to using them.
