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:

VMware ESX/ESXi 4.1 host with Broadcom bnx2x (in-box driver version 1.54.1.v41.1-1vmw) experiences a loss of network connectivity and a purple diagnostic screen:
We have not experienced this and we are using the 1.54 driver (it replaced the 1.48 driver when we did the vSphere 4.1 upgrade).
I called VMware tech support today, and they will have a 1.6x driver out 2nd week of November which should address this and other issues.
Vmware tech I spoke to said use the 1.6 driver and not the older 1.48 driver.
We still have a open ticket because we are not getting any networking performance info in vCenter using the 1.54 driver.

SOIC watches I/O latency across the datastores shared in a VMware Cluster and enables each VM it's fair share of disk resources in times of contention when a certain latency value is exceeded (30ms by default). This ensures one disk intensive VM doesn't impact other VMs disk performance. You can also "tweak" and say some VM need priority access in times of contention as well (at the expense of the other vms on that datastore though).
· Storage I/O Control is supported on Fibre Channel-connected and iSCSI-connected storage. NFS datastores and Raw Device Mapping (RDM) are not supported.

The highlight for all at VMworld 2010 this year had to be the most excellent LAB environment we have every experienced! At first I was concerned because they had done away with most of the large Instructor led labs this year. The hands-on labs were a much better way to go for sure. With a very professional layout, awesome menu, hardware, and cool room, you got to sit down and really go through learning about the products at your own pace (with nice instruction guides that explained stuff, not just told you to click and type this and that).
The labs were open 8am-10pm first two days, 8am-6pm Wednesday, and 8am-4pm on Thursday...so you had plenty of time to really take advantage of this wonderful resource. There were 30 lab topics, 480 lab seats, and 44 hours of lab time. Total lab clouds delivered were 15,344 with a total of 145,097 VMs created! WOW! Every hour the lab cloud created and destroyed about 4000 virtual machines! (All of these stats and information are from this link).
The labs utilized PC-over-IP protocol and Wyse P20 stateless zero clients using VMware View 4.5. More details on this configuration can be found here.
The top 10 labs taken were:
- VMware View 4.5 Install and Config (1515)
- VMware vSphere Perf & Tuning (1229)
- VMware ESX 4.1 new features (1112)
- VMware vCloud Director Install & Config (1019)
- Basic VMware vSphere Install & Config (829)
- VMware View 4.5 Advanced (811)
- VMware vSphere Troubleshooting (791)
- VMware vCenter SRM Install & Config (789)
- VMware vDS & Cisco Nexus 1KV (761)
- VMware vShield (734)

I received a special invite to see a new awesome storage solution specifically tied to "The future of VMware Storage" at VMworld 2010. President and CEO, Paul Maritz, of VMware will be speaking at the event and probably mentioning the new EVOSTOR EVOLUTION 1200 storage solution. Evolution 1200 is specifically tied to vSphere and the new vStorage API enhancements.
- purpose-built for VMware environments
- EvoStor removes the complexity managing LUNs or file systems
- first and only VM-level storage system
- VMware admins can create a VM and simply assign the capacity they need
- no worry about sizing, performance, optimization or reclaiming storage capacity
- EvoStor GUI is built right into vSphere
- single pane of glass to create VMs and provision storage
- Multi-tiered storage supporting SSD, SAS and SATA disk drives

|Well here is my proposed schedule, of course this could be all subject to change since nothing can be reserved this year. |
My advice though, is spend time in the Hands-on-Labs with the different products, Intructor led labs, Vendor area (every vendor you can imagine in one place), and networking with others! After all, breakout sessions you can always watch later when they are made available.

""We have the chance, the opportunity, but also the responsibility to show leadership in how licensing should be done in a cloud world," he said during a recent interview. "We need to get better alignment between value received and what customers are paying for."
How it might work:
You estimate your needs for the next year and buy licenses to meet those needs. Over the course of those 12 months, vCenter Server calculates the average number of concurrently powered-on VMs running the software. And if you end up needing more licenses to cover what you used, you just reconcile with VMware at the end of the year. (If you end up needing fewer licenses, VMware won't reimburse you, but as Balkansky pointed out, there's really no need to overestimate in the first place.)
Another factor that may be good about this change as it may allow more companies to adopt an easier pay-for-vm policy.

If you missed this wonderful event held in Charlotte each year, this is a video Dave Davis (AKA vmwarevideos.com training) made of are very good expert panel discussion. The experts were Chad Sakac of EMC, Vaugh Stewart of NetApp, Scott Lowe of EMC, Mike Laverick of RTFM-Ed.co.uk.
The first question to get things started is presented by myself and it really got some interesting conversation going.
This is a nice video showing off the new STORAGE I/O Control feature expected to be in the VSPHERE 4.1 release. This is the first in several storage improvements I think we are going to see from VMware…and shows why VMware is leader!

EMC VPLEX-VM TELEPORTAT
More info is coming out about this major "virtual revolution" as big if not bigger than vmotion and storage vmotion.
"VPLEX enables a storage device is simultaneously presented at both the local and remote side in a read/writeable state in an active/active model – any IO can be served by any VPLEX node, by any port – at anytime."
"VPLEX is the first application of this core technology and is a shipping, generally available product, and can be used with ANY array."
- Use Case #1: vMotion between different vSphere ESX clusters being managed by a single vCenter.
- Use Case #2: stretching an vSphere ESX cluster across geographic distance.
