Storage Directions for the Software-Defined Datacenter

The demand for services in datacenters is steadily growing as companies recognize the value of setting up or growing a service in seconds or minutes and of able to increase business agility.  Traditional datacenters have made use of a great deal of specialized hardware, requiring a large amount of manual configuration and management, as well as complex resource management.

A Preview of Distributed Storage

VMware shared a technology preview of Distributed Storage at VMworld 2012 as part of our broader storage strategy . Steve Herrod described this technology as “virtual SAN” in his Day 1 keynote at VMworld. Distributed Storage (DS), currently under development by VMware engineers, is a distributed layer of software running natively as part of the ESX hypervisor. It aggregates the hosts’ local storage devices (SSD and HDD) and makes them appear as a single pool of storage shared across all hosts. In other words, we are doing with local storage what we have done in the past with CPU and memory – virtualize the physical resources of ESX hosts and turn them into pools that can be carved up and assigned...

View Storage Accelerator – VMware’s next step towards more reliable, more cost-effective storage for VDI environments

May 17, 2012
By

VDI with VMware View has brought many benefits to customers over the years, including business agility, improved control and security and end-user flexibility. However, a vexing problem as our customers scale up the size of their deployments has been how to achieve cost-effective storage designs for VDI environments while maintaining an excellent quality of service for their end users. The “VDI storage problem” fundamentally stems from the different economics of traditional desktop storage (a local SATA drive), and datacenter-class storage. Datacenter storage is almost always more expensive on a $ per GB, or $ per I/O throughput basis. However, at the same time, datacenter storage offers significant opportunities for pooling resources, securing, consolidating and centralizing the data of the desktop. VMware has always been...

Is Cloud Storage going to disrupt Traditional Storage? – Part2: What is Blob storage?

Cloud-scale Blob is the new category of storage designed specifically to meet a very relaxed set of requirements uniquely selected to match the needs of the majority of bytes of data for new media types. Gone are the complex constraints of concise consistency, the ability to randomly update the object, or any sort of concurrency/locking semantics. In fact, the majority of Blob stores today support just create/append/delete, and most have no namespace.     Capability POSIX File System Cloud Blob Namespace Yes No Create Yes Yes Read Yes Yes Update Yes Most offerings NO Append Yes Yes Delete Yes Yes Locking Yes No Read-after-write guarantee Yes No Access control lists Yes Yes Authentication Yes Yes Meta-data per object * Yes Search/Query No Yes |...

Is Cloud Storage going to disrupt Traditional Storage? – Part1: The demise of expensive datacenter storage

Introduction   Recently, I’ve been looking at changes that are unfolding for the ways personal users store and manage data, and server applications use, store and manage data. I see some significant trends that radically change the way new types of storage systems are structured.   When we think of storage architectures, we typically separate our thoughts about personal data stored on our local systems, and the big enterprise storage systems used to store all that “mission critical” data. I’m going to walk through some trends that will substantially affect both of these now disparate areas, and the inevitable merger of the systems that store and interact with both types of this data.   In the first installment of this short series, I will...
