Intel said this morning that is has tweaked its Xeon firmware and sold it off to Oracle, in an
effort to streamline things a bit. The two companies announced late yesterday that they had partnered to work on a Xeon chip whose
cores can be turned on or off and where the clock speed can be easily changed and tailored by Oracle's
To be sure, Intel's new Xeon E7-8895 v2 SKU was carefully 'adjusted' by Intel to allow Oracle's
code to choose how many of the chip's fifteen cores to use at any given time, and at what clock speed,
said Intel spokesperson Pat Buddenbaum.
Although these three new features-– clock rate manipulation with Turbo Boost, selective power C-states,
and the ability to dial-up and dial-down cores have been available in prior Intel chips, this marks the
first time they've all been available in a single Xeon CPU, we're told.
This allows Oracle to run systems at full processing capacity when a heavy workload arrives,
and spin down the CPUs in quiet periods, all of which should save some energy.
Additionally, the fewer cores used, the higher the clock frequency can go in Turboboost mode,
which is useful for certain kinds of processor-intensive applications.
The 22nm-process E7-8895 v2 has fifteen cores running at a typical clock speed of 2.8 GHz, though
it can use "Max Turbo" to scale up to 3.6 Ghz.
It has 37.5 MB of data cache. Its maximum thermal design power (TDP) is 155 Watts, which in technical
terms is a very hot chip when compared to other similar designs.
The CPUs must be able to reliably work over a range of several clock frequencies, grouped into
grades called "bins". One bin represents a 100 MHz increment in clock frequency for the E7-8895 v2,
Intel told us.
"Let's just say that this is a fifteen core part at the outset, running under mostly favorable conditions
that allow for Turboboost. It can theoretically run at one bin or two bins to three bins above rated
frequency," said Intel.
"Depending on all the many conditions that enable that, you can hit any one of those points. Three
bins is the maximum at the 15-core mark, but as you go lower, say to a six-core mode, then the maximum
frequency within that particular situation is 3.4 GHz. If for some reason only one core is being used,
then in that particular scenario you can go up to 3.6 Ghz," said Intel.
The chip giant spent about a year working with Oracle to help the company tweak its software and
schedulers to automatically scale core usage up and down, and make better use of its power management "C-state"
technology that Intel made available through firmware tweaks, Intel said.
"It's more through the unlocking of features in the chip, but also through our manufacturing
process there will be a more stringent thermal profile required such that the chip supports all of
these different modes," Intel added.
This marks a continuation of one of Intel's major new strategies-- customizing its high-margin
server chips for specific customers, like eBay or Twitter.
Another aspect of this is its announcement of sitting FPGAs directly on top of Xeons for off-CPU
Previously, Intel's customizations have involved different power management methods and selecting
some chips for particularly high sustained clock frequencies, but Buddenbaum believes this is the
first time Intel has sold a chip with dynamic core-scaling targeted at servers.
Though Intel makes much of the customization itself, it hasn't done anything from a hardware
perspective besides select for the best Xeons coming off its production line.
The magic is all in the firmware unlocking some chip features. The new chips will sit inside Oracle's
just-announced Exadata Database Machines X4-8, which have been built for Oracle's "in-memory" database
This new server design is "specifically optimized for a new generation of workloads: database as a
service (DBaaS) and database in-memory. With up to 12 terabytes of DRAM memory, the Exadata Database
Machine X4-8 can consolidate hundreds of databases and can run massive databases entirely in-memory,"
The new server can feature 12 TB of memory per 42U rack, 672 TB of disk storage
and up to 44 TB of PCIe-linked flash as well.
"This new customized version of the Intel Xeon processor E7 v2, developed in collaboration with Oracle, helps
maximize the power of the Exadata Database Machine X4-8 by elastically accelerating peak performance
of database operations, while also reducing the data footprint," said general manager of Intel's Data Center
Group, Diane Bryant.
In other IT news
Big Blue has been following the amazing success of Apple's very popular iPhones and iPads
with great interest in the past two years, and now the IT behemoth has decided that it wants
part of the action.
IBM and Apple late yesterday announced a new partnership to maximize each company's strategies.
Starting sometime this fall, Apple is delivering devices exclusively to IBM, which the IT giant will
then integrate with industry-specific apps for business and enterprise customers.
The idea is to provide specialized Apple devices to companies in banking, health care, insurance,
retail, travel and transportation, to name just a few.
Big Blue said it will carefully listen to the specific needs of its huge list of business clients
spread in over 250 different industries.
IBM will then craft tailored software that addresses those distinct needs. "For the first
time ever, we're placing IBM's renowned big data analytics services at Apple iOS users' fingertips,
which opens up a huge market opportunity for Apple," Apple CEO Tim Cook said in a statement, calling
the new partnership "a radical step in the immediate future of both companies."
IBM CEO Ginni Rometty promised a "transformation to the way people work, industries operate and
companies perform over the long haul."
No specific date has been set yet, but beginning sometime this fall, the iPhones and iPads will
only be available through IBM representatives to meet their business clients' distinct needs.
They will include a private app catalog, data security services and a lot more, Apple and
An IBM spokeswoman said it was too early to give some examples of what kinds of business apps would
The two companies also said Apple devices would use IBM's vast and powerful cloud services, which
offer data storage, various enterprise services and flexible work-sharing capabilities.
The new alliance makes sense on several levels. First, industry specific apps will lock down
Apple's iOS market share in the enterprise segment.
Apple's iOS market share vs Google's Android share in the enterprise segment is the inverse
of the consumer space. IBM gets to package iOS apps, embed its analytics tools, and then use its vast
IT services and sales channel to offer those business apps to corporations.
Then, Apple gets a key enterprise partner without having to exclusively build and market apps to
corporations. And of course, IBM also gets 'Apple's cool factor' that is legendary with all its users.
Consumerization will only go so far for Apple's enterprise ambitions, so this new deal is a win-win for both
Forrester analyst Frank Gillett welcomed the new alliance-- "The Apple-IBM partnership is a
landmark agreement, in our view. Given IBM's strong market strength and coverage in the business apps segment,
this alliance gives Apple enterprise capabilities and credibility in just one stroke, and gives
IBM a premium advantage in the race for mobile enterprise leadership. Look for Google and leading
enterprise suppliers to seek similar partnerships that offer a credible alternative."
But of course, Apple's and Big Blue's win will cause other companies some pain, beginning
with Google's Android. That operating system has some partners in the enterprise segment, but
it's also an OS that has had more than its share of security issues lately.
And the Android OS has too many different versions to contend with, making that platform a bit
challenging to manage. There's a reason iOS leads in enterprise market share. Gillett's point that
Google will need partnerships is well taken. The problem is that it's going to be difficult to match
IBM's coverage in just one pass as this new Apple deal will demonstrate going forward.
Then you have Samsung-- The South Korean company's business-to-business (B2B) unit has been
the biggest leader of Android in the enterprise segment, up until today that is. An IBM exclusive
with Apple's iOS basically locks out Android in the industry specific application department.
Now let's talk about Microsoft. Up until now, the software behemoth's biggest goal was to get
Windows IT departments to go with Microsoft on the mobile segment. Now IBM and Apple will simply squash
Microsoft's mobile device management and collaboration platform will still be around for a while,
but expect the company to be challenged with this new IBM-Apple exclusive deal.
And BlackBerry in all of this? The struggling Waterloo, Ontario-based company is now caught right in
the center of an iOS and Android enterprise war, to say the least. Although Blackberry did pioneer (to a certain
degree) secure business email messaging apps about eleven to twelve years ago, that lead is now gone, most
industry experts say.
Finally, Oracle and SAP will also suffer as well. Both enterprise software companies have
been pushing their business apps in enterprises with a focus on industries they dominate. But for
businesses thinking mobile first, and globally, they number in the millions now, IBM just plowed its
way into that vast and very lucrative market in just one scoop. And Apple will also benefit handsomely
with this deal as well.
