Well if it is up to VMware founder Mendel Rosenblum the answer is DRAM.
The Project "RamClouds- Scalable High Performance storage Entirely in DRAM" sounds very interesting.
Find out more about the project here: http://www.stanford.edu/~ouster/cgi-bin/projects.php
The paper "The Case for RAMClouds: Scalable High-Performance Storage Entirely in DRAM" can be downloaded from this location.
Original posting and Discussion: http://www.ntpro.nl/blog/archives/1663-Hey-Drummonds-forget-SSD-RAM-is-the-future.html
The solution: one possible solution is to shift the home of online data from disk to DRAM. A RAMCloud is a new class of storage intended for datacenters, where all information lives at all times in fast DRAM. Large-scale systems are created by aggregating the main memories of thousands of commodity servers. RAMClouds are interesting because they combine large scale (100-1000 TBytes) with 100-1000x faster latency than current systems (5-10 microseconds to access small amounts of RAMCloud data from application servers in the same datacenter). In addition to simplifying the creation of large-scale Web applications, we believe that RAMClouds may enable a new breed of data-intensive applications.
A product available now RAMSAN: http://www.ramsan.com/products/4
The RamSan-440 is a new solid state disk with record high performance, record high capacity for a RAM-based system, and a combination of features that help ensure the highest availability of data to its users. The RamSan-440 is the world's first non-volatile RAM-based SSD to sustain 600,000 IOPS (input/outputs per second) and deliver 512GB of storage capacity in a 4U rack-mount chassis. It's also the first SSD to use RAIDed NAND Flash storage modules for data backup, and the first system to incorporate Texas Memory Systems' patented IO2 (Instant-On Input-Output) technology

Nice article to setup a VEEAM product LAB in one virtual machine:
"Veeam products can be installed on the same virtual machine allowing administrators to easily create a cost effective and valuable solution for documenting, managing, and maintaining ESX datacenters. With the recent announcement of free Veeam NFRs for VCPs, VCDXs, vExperts, and VCIs, many will be looking to build VMs to explore Veeam products. This post serves as a high level guide for combining the free versions of Veeam Reporter,Veeam Monitor, and Veeam Business View to create a single "Veeam ONE" Monitor PlusVM."
I know the Per VM licensing changes for say SRM helps those wanting to protect Risk 1 and 2 virtual machines in an affordable way. But if I was a big VMware customer that had really wanted to use SRM to protect everthing…this seems to KILL that Idea COST wise.

· Cloud Architect (EMCCA) certification is targeted toward architects who deliver virtualization and cloud designs based on business strategies encompassing all key technical domains (compute, storage, networking, applications, etc).
· Data Center Architect (EMCDCA) certification is for architects and designers who provide detailed designs for information storage specific technical domains to complement, expand, and complete their overall virtualization and cloud design.
Both tracks are based on 'open' curriculum where the focus is on technology/principles rather than specific products (similar to ISM design).For more info see these links where you can learn more:
