The term “noisy neighbor” in the storage context refers to a rogue virtual machine (VM) that periodically monopolizes storage I/O resources to the performance detriment of all the other VM “tenants” in the environment. This phenomenon can become more pervasive…
An All-Flash Array is a performance sledgehammer. It shatters the performance problems that most data centers face and will likely continue to do so for years. Unlike traditional hard disk systems, most data centers that purchase an All-Flash Array won’t…
Leveraging Software Defined Networking For Better Scale-out Storage
Intelligently placing data within a storage system is not necessarily a new concept, but leveraging software defined networking to make decisions about data while it’s still in transit is. When software defined networking and software defined storage are combined they can overcome some of the challenges that high performance scale-out storage systems encounter. As a result these new, software defined, scale-out systems provide highly flexible, highly reliable and highly cost effective storage systems that can support a wide variety of workloads.
Learn:
– The challenges when Scale-out architectures
– How flash exposes even more challenges
– How Software Defined Networking can lead to better scale-out storage
The removal of latency is a critical part to delivering more fully on the flash performance promise. No matter how fast the flash technology becomes, the latency of its connection to the CPU is a key stumbling block in achieving…
In a recent webinar focused on reducing latency of the flash interconnect, we asked a polling question “Where do you primarily use flash today?”. As you can see from the results users are still trying to figure out how and…
The typical performance metrics used to categorize flash performance are throughput and IOPS. The most important metric may actually be latency. The elimination of latency has become a top concern for customers and flash vendors. That has led to solutions that…
In theory, scale up storage appeals because the data center can start small and add capacity and performance as needed. Do these theoretical advantages apply to the use cases in which All-Flash storage is most commonly deployed; databases and virtualization?…
Next up at Storage Switzerland’s EMC Briefing Day was the Midrange part of EMC’s Enterprise & Midrange Storage Division, also known as the VNX family; and of course we are going to talk about the VNX2. The EMC VNX2 is…
It’s no surprise that traditional storage performance falls off a cliff in heavily virtualized server environments. Originally designed to interface with a limited number of hosts, legacy dual controller storage architectures simply cannot meet the I/O workload demands of multiple…
How to be intelligent about flash storage deployments Storage performance has become a “hot button” issue in the server virtualization era. While there is a need for high performance storage, such as flash and hybrid storage solutions, there is a…
