Apple’s New MacBook Pro with Intel’s Thunderbolt is Overkill for Storage Unless You’ve Got the Bucks
Last week, Apple introduced a new MacBook Pro sporting a new interface port employing Intel’s Thunderbolt (aka Light Peak) technology. Though originally designed as an optical interface, cost pressure from its OEMs caused Intel to provide its first commercial chip using this technology with a copper-only interface.
Nonetheless, Thunderbolt is an impressive chip that provides two bi-directional channels operating at 10-Gbits/sec. That’s a total of 40-Gbits/sec and is up to 20 times faster than USB 2.0 and more than 12 times faster than with FireWire 800! Moreover, these chips will transparently carry both PCI Express (x4) and DisplayPort protocols and up to six devices can be daisy chained together. What’s more, Thunderbolt offers a low latency with 8-nanoseconds accuracy time synchronization across 7 devices.
Founded in 1967, Dataram is a worldwide leader in the design and manufacture of reliable, high capacity and innovative memory solutions. Dataram provides customized memory solutions for OEMs and memory upgrades for leading brands including HP, IBM, Sun Microsystems, Dell, Intel and AMD Opteron.
In 1976, Dataram invented the first SSD called BULK CORE which attached to minicomputers from ModComp and emulated hard disks made by DEC and Data General. Each chassis held 8x 256k x 18 RAM modules and had a capacity of 2 megabytes.
I was given the opportunity to speak at the Storage Decisions Conferences in June 2009, June 1-2 in Chicago and June 16 in Toronto. I was delighted to speak on two topics, Integrating Solid State Storage, and Unified Data Center Network Infrastructure (also known as Converged Networking). I was able to have some great conversations with a number of end-users around these and other technical topics. More on that a bit later.
For weeks the brain trust at Wikibon and I have been dissecting EMC’s V-Max announcement and we still have a ways to go. Our technical guys want to go even deeper and we need to put together a good roadmap to help clients go from where they are today to this new vision of the virtual data center– if that’s where they really want to go.
Why Wouldn’t Customers Want to Migrate?
EMC announced their latest 3rd generation Symmetrix architecture today the labeled the Virtual Matrix Architecture. The announcement was kicked off by Tucci who positioned the event as both the introduction of a new architecture as well and the introduction of the first V-Max product. Donatelli then proceeded to give a bit more detail. The following are the highlights I captured during his presentation.
- Symmetrix was introduced 18 years ago, this is the 3rd generation architecture.
- The intelligence and the compute resources are contained in a module called the Symmetrix V-Max Engine. Multiple engines can be matrix together with capacity resources in a scale-out architecture.
It was another successful and busy week at Storage Networking World (SNW) Spring 2009 in Orlando. Although the number of vendors, by my count, was 48% of what it was in Spring 2008, it was apparent that the vendors who did participate sent fewer people. However, the SNW officials said that the end-user attendance was 92% of what it was in Spring 2008. Obviously travel budgets have been cut, and this was reflected in the end-user attendance, which had shifted to many local IT professionals from the central Florida region.
The Spring 2009 Storage Networking World ends today. It was a busy week for the Wikibon team as we were briefed by more than 25 technology companies and tweeted the live action to the Wikibon community. Bill Mottram, Dennis Martin and I gave presentations during the week, Dennis on SSD for Microsoft Apps, Bill on optimizing energy and efficiency and me with Rich Avila on how Virtualization Energizes Cal State U East Bay.
When you read the Fusion-I/O Specs, they have an access time of 50 microseconds, and 95,000 IOPS for the 160GB SLC ioDrive; that’s over 100 times faster than a traditional disk drive. Look at EMC’s assessment of the potential of flash and you see a more sober assessment of 10-30 times faster. So is Fusion-I/O a much better product and set to dominate the market?
When you look in detail at the spec of the Zeus IOPS 3.5 inch SSD from STEC which is used in the EMC storage arrays the difference between the two technology’s are minimal. Clearly the difference in performance comes from the overhead of running the SSD in a storage array. Is using a disk-drive form factor for storage a wrong decision?
