The Challenges Of VMworld

8/31/2010
VMworld kicked off yesterday, and despite the crowd, everything seems to be under control. The media/analyst area is no exception. It is under strict control (i.e. too much), making it very difficult for industry people like myself to get information to you about what is going on at the event. VMworld organizers will let the analysts and press in the area, but not the vendors we need to speak to. Anyone see a problem with that?

Primary Storage Deduplication: GreenBytes

8/31/2010
I concluded in a recent blog entry "Do We Need Primary Storage Deduplication?" about how primary storage deduplication can bring significant value to the data center, and it is becoming a must for suppliers to provide. In our own testing on two different deduplication platforms, we are seeing an almost 70 percent reduction of capacity requirements on real world data sets.

3PAR And HP Vs. Dell: Its On!

8/26/2010
As last year's duel between NetApp and EMC showed, there is nothing more fun than a bidding war, especially if you are the company being sought after. It also makes it so much easier to come up with blog content. As expected, Dell has countered HP's bid for 3PAR and made it clear to everyone that the quest for enterprise class storage virtualization is on, or to at least make HP spend more money.

Will HP-3PAR End EVA?

8/24/2010
Why is 3PAR so important and why are they getting billion dollar offers? Fellow Network Computing contributor Howard Marks outlines the specifics in his most recent entry. In short, 3PAR has been an innovator in the space. My concern with Dell-3PAR or HP-3PAR is wondering whether innovation will continue? Also, s HP prepared to make the hard choice to end its EVA storage solution?

Solid "Slate" Storage

8/23/2010
In my last entry, I discussed how solid state storage could make its way into the enterprise. What is sometimes forgotten in that discussion is that the other markets solid state storage participates in potentially dwarf the enterprise market. One of the subjects made clear at the Flash Memory Summit was how big the market for smartphones and slates or tablets like the Apple iPad is going to become. Solid "slate" storage may end up dwarfing every other market that solid state storage participate

When Will Solid State Dominate? It's Not That Complicated

8/19/2010
Sitting at the very well attended Flash Memory Summit, by far the number one question being asked is "When will solid state storage dominate the market?" Is it really that complicated? SSD domination or at least acceptance, like all things in storage comes down to performance, reliability and price. While performance should be a clear winner for solid state storage there are issues to be addressed. The first is dealing with write performance.

The Inhibitors To I/O Virtualization

8/12/2010
In my entry "I/O Virtualization: When, Not If," I discussed some of the merits of I/O Virtualization (IOV) and the value in offloading I/O responsibilities from the hypervisor with SR-IOV (single route IOV). While SR-IOV and IOV may seem like great strategies, there are some inhibitors that need to be overcome. The first is OS or hypervisor support, and the second is dealing with the disruptions to the network and storage infrastructure when first implemented.

Breaking Down Vendor Strategy In New Markets

8/10/2010
As manufacturers get larger, they sometimes begin to look at other adjacent markets that they can get into to leverage their current market position. One example might be a SAN array manufacturer deciding to sell a disk-to-disk backup solution or developing a new feature for their existing solution, such as adding deduplication. How they decide to accomplish this task and how committed they are may directly impact the customer.

I/O Virtualization: When, Not If

8/5/2010
I/O Virtualization (IOV) is an I/O card-sharing technology that lets multiple servers share multiple cards across a single, high-speed cable segment. The general purpose of IOV is to make it easier to share bandwidth among servers in a rack. The cards to be shared are placed in a gateway, and the servers connect to that gateway. Cards are typically shareable on a per-port basis. For example, a quad-port Ethernet card could be assigned to four different servers. The ports or cards can be quickly

What Comes After Dedupe?

8/4/2010
There has been a lot written about deduplication. It has become commonplace in backup and is quickly becoming a requirement in primary storage. Once every system has in some form and deduplication is broadly available, what do we do next to optimize storage? After all, storage growth isn't going to stop and while deduplication and compression will slow some of that growth we know that files will continue to get larger and the number of files that are created will increase.

2014 State of Unified Communications
If you thought consumerization killed UC, think again: 70% of our 488 respondents have or plan to put systems in place. Of those, 34% will roll UC out to 76% or more of their user base. And there’s some good news for UCaaS providers.
