HP blade chassis is dense and intense

by admin ·

If you’re looking for the ultimate in computational density, consider the HP C7000 Platinum Blade Server Chassis. The C7000 packs an enormous amount of power into just 10U of rack space, with modular components that can be almost instantly changed out.

Inside the blade chassis, HP has inserted a mezzanine backplane that moves at 7.1Tbps in aggregate. In turn, HP’s FlexFabric connects to backplane components that fan out data in connections of up to 40Gbps per channel, and can be aggregated as control units of four blade servers—conveniently the number that will fit in a 42U rack, provided you’ve pleased the power company and your data center has the correct load bearing floors.

At $122,000, the unit we tested was a monster, sporting two blades plus the FlexFabric connectivity gear.

One point to keep in mind. Once you go the blade chassis route, you’re locked in to HP as your vendor. We could find no one else that sells products for this chassis, so a purchase means a marriage with HP. Of course, the same applies to nearly all blade system designs. HP offers a three-year, across the board warranty once you say the vows.

Testing HP’s C7000 blade chassis was an exercise in both server geometries, and also in hunting down strange configuration data. The base software management options to configure the beast that is the C7000 chassis require enormous amounts of sophistication.

Rather then use the default options, we recommend buying the OneView 1.1 management app. In fact, beg for it if you’re managing several HP blade server chasses.

We like the C7000 chassis and especially the blades, BL-660 Gen8s with a lot of computational power, but it’s the back side of the chassis that packs the most punch with HP’s flexible Virtual Connect option.

Network operations center personnel will enjoy the rapid deployment of the hardware, but there were a few things missing in our opinion when we compared standard and optional administration software packages for the chassis. What’s there works, and well. What’s missing is mildly frustrating.

What We Tested
We tested the C7000 “Platinum Chassis” which, in and of itself, is comparatively inexpensive. The chassis is powered via 208-240v 30amp+ connections, and there are six power supplies; HP sent a Power Distribution Unit (PDU) and we recommend using one for fast power supply change-out should something go awry.

Two full-height HP BL-660 Gen8 blades were fitted to it. The basic blades are not quite $28,000 each (memory not included). Two HP Virtual Connect FlexFabric 20/40Gb F8 modules were installed, each nearly $23,000. Eight full-height blades can be installed, or a combo of 16 half-height blades.

Blades and the Virtual Connect components together, salted with a bit of memory (256GB) made the price climb into six figures. Admittedly, what we received can also be the administrative core for up to four total chassis, which won’t be quite as expensive when the cost is amortized over subsequent chassis and blades. The density can be huge. The chassis fan count—10 of them—was also huge. This density needs to breathe.

The BL-660s Gen 8s blades came with Intel E5-4650 CPUs, 4CPU x 8-core, total 32 cores, 128GB memory (the minimum, 512G possible), and two drives each. We found we could easily boot from SAN or network resources. HP’s VC FlexFabric 20/40 F8 Module was installed into the rear of the C7000 Chassis, along with HP FlexFabric 20Gb 2-port 630FLB Series adapters.

The chassis and components that fill the C7000 are joined together into a mezzanine backplane as mentioned, and blades communicate among each other, or with network communications options installed in the rear of the chassis. The chassis monitors the front and backplanes via both external software that talks to internal chassis firmware, and can be directly controlled through a front-panel color LCD control panel or rear-mounted display.

Provisioning of the chassis components (blades, switches, and their configuration) is done remotely. There are no USB jacks on the front of the chassis and the blades have no jacks. There is one VGA port on the rear, and one USB jack that can mirror the front panel display. We jacked into the back of the chassis with our crash cart, and discovered that the crash cart KVM version of the chassis firmware-driven software doesn’t do much more than the front panel display. But you’ll need one or the other to set the chassis IP address.

Virtual Connect Manager vs OneView

The C7000 is useless without control software. There are two basic choices. HP’s Virtual Connect Manager is included in the cost of the chassis. Also included with all Gen8 servers is HP’s integrated LightsOut (iLO) management.

HP’s OneView might be a better option. It’s a broader management package for Gen8 servers, although it’s not inexpensive.

We recommend those deploying the C7000 use OneView rather than Virtual Connect Manager for several reasons: it’s archaic and requires studious prerequisite study just to install the software onto highly configured Windows 2008 R2 server, needs 6GB of user memory and therefore is notebook unfriendly, and requires much architectural forethought to deploy into an effective control plane for provisioning and managing the options of the C7000 chassis and its components.

By contrast, OneView 1.1 is a virtual machine delivered as an appliance for VMware or HyperV, installs rapidly, and after a fast tutorial, becomes instantly manageable. It’s not inexpensive. The trade-off is in installation hours spent, and manageability. OneView has the ability to discover much infrastructure and when supplied with chassis password components, is able to connect and logically associate components quickly and with surprisingly little fuss.

There is connectivity between both applications and systems management applications such as Microsoft’s SystemCenter, but these were not tested.

To summarize, the default package can be used, but HP recommended OneView, and we concur. That HP doesn’t include it with a substantial purchase of blades frustrates us. Any data center deploying many chassis can’t live without it.

Blades and FlexFabric

The twin BL 660 Gen8 blades that we were sent had 32 cores on four Xeon CPUs. We’ve seen this combination before and it’s fast and solid. Across the chassis with eight of these installed, 256 cores are possible. If a rack supports four full chassis, that’s 1,024 cores per 42U rack, yielding huge density. Old timers will remember when there was one 32bit CPU per tower server.

The connectivity options for FlexFabric are numerous and the fabric is controlled via the configurations set by Virtual Connection Manager or OneView. The HP Virtual Connect FlexFabric-20/40 F8 module we used replaces internal switches in former HP blade chassis. It supports 16- 10G/20GB downlinks to the chassis midplane bus, two 20GB cross connect links, four 40GB uplinks, eight Flexports uplinks, plus a link to the Onboard Administrator module (the chassis firmware app). The Flexports can be either Fibre Channel (2/4/8GB) or Ethernet (10/1GB).

Each blade can have logical network interface card (NIC) connections depending on the blade type, typically two NIC logical connections for a half-height and three for a full-height blade. These attach to the mezzanine plane, and it’s here that IP traffic can be separated internally from iSCSI or FCoIP disk traffic, or in another design alternative, one tenant’s traffic from another, or perhaps a Content Development Network (CDN) from the Hadoopers.

Amusingly, the extreme data rates of the FlexFabric infrastructure also mean cable length concerns—at 40GBps proximity becomes an issue when establishing boundaries between chassis—occur certainly with copper cables but even with fiber.

The density also means that the FlexFabric options chosen become/replace traditional hardware core routers and switches that once performed the tasks among what would have been the huge stack of discrete servers, or aisles of servers in racks and its network switching demarc boundaries.

FlexFabric’s options and construction mandates inter-disciplinary imaginative construction and another reason why OneView trumps Virtual Connection Manager for fabric control, as OneView integrates these at the mezzanine/midplane level more understandably.

We appreciated the multiple views of OneView fabric tracking, and how it relates each element of the infrastructure to each other. It’s not a finished product, as it has difficulty showing sophisticated logical and protocol relationships in and among the objects, and this would help systems engineers understand flows, and network engineers understand the hardware and aggregation relativity more simply.

Whether we wanted it or not, we felt as though we should get a degree from HP after going through the exercise of understanding the relationships that we were constructing.
Testing

Our initial installation went smoothly. The front panel LED provides a lot of information about the chassis, and errors that the firmware picks up, like unplugged cables, and cooling problems. It’s a fast way to get localized information on low-level problems, but it’s not as sophisticated as even a dull smartphone as a user interface. The KVM jack supplied us with a web page, but not that much more control capability. Control comes from Virtual Connect Manager and/or OneView or Insight Manager.

We have nothing that can assault this chassis at full bore. It’s in aggregate, an enormous block of computational and I/O capability. The sum of its parts when viewed discretely however, is powerful—blades whose other Gen8 cousins we’ve tested coupled to a huge L2/L3 switch backplane.

The BL-660 Gen8 blades digested our VMware licenses with glee. The speeds of digestion were comparable to the HP DL-580 Gen8 we recently tested. The flow of data through the blades with VMware’s VNICs was easily controlled via defaults in OneView, then in VMware vCenter with ESXi 5.5. Where we once had difficulty with VMware drivers finding HP hardware correctly, we had no issues this round.

Summary

The C7000 Platinum Chassis, coupled to the HP-supplied BL660 Gen8 blades supplies huge computational density. The FlexFabric approach localizes all systems I/O to a mid-plane, then logically connects multiple blades and chassis together through the fabric.

This architecture replaces discrete or 1U servers, external switch and router cabinets, separate fabric to SAN data stores, and all of the logic needed to glue these pieces together.

Going the blade chassis router, one becomes entirely captive to HP in this infrastructure, but it’s a flexible infrastructure, plays well with VMware and Hyper-V (and likely others). There are necessary options that aren’t included in the price—the most glaring example is OneView, which costs $400 to $799 per server (as much as $50 per core).

A 256-core fully loaded chassis approaches $300,000—just less than $300 per core—including all I/O fabric communications needed to connect to a communications demarc, and not counting OneView or other licenses—or hypervisors or operating systems.

How We Tested

We installed the C7000 chassis into our rack at Expedient-Indianapolis (formerly nFrame), then connected its power. After the lights dimmed and the grid twitched, we connected the FlexFabric connectors to our ExtremeNetworks Summit Switch core internal routers. The password to the C7000 chassis is hidden inside. We didn’t know this. Remember to get this password because nothing really works until you do.

We bought up a VMware “.ova” appliance version of HP’s OneView 1.1, and with help from HP, brought the chassis online, configured the chassis, and made it part of its own group; up to four chassis can be aggregated as a unit.

We used VMware and Microsoft Hyper-V Windows 2012 R2, one on each blade that was supplied, as an exercise, and checked to see if each hypervisor’s discover process found the items we would supply via changes in the FlexFabric configuration, including IP resources as well as internal Dell Compellent SAN fabric we use. We often had to bury ourselves in technical docs, which are complete but offer few real-world examples, to connect items, but met no obstacles in any of the configuration scenarios we tried.

We thank the personnel of Expedient for their tenacious support of remote-hands work needed to complete test cycles.

HP ends tough year on a high note

by admin ·

The company reported higher-than-expected revenue and a return to growth in its enterprise business

Hewlett-Packard reported results for the last quarter of its fiscal year on Tuesday, and although sales were down from a year earlier there were some much-needed signs of improvement.

HP’s enterprise division, which sells servers, storage and network gear, reported its first sales growth in two years, and its PC division, which has been hammered by the popularity of tablets, shrank less than it did in prior quarters.

“Through improved execution, strong cost management, and with the support of our customers and partners, HP ended fiscal 2013 on a high note,” CEO Meg Whitman said in a statement.

Overall, HP’s revenue for the quarter ended Oct. 31 was US$29.1 billion, the company said, down 3 percent from a year earlier but better than the $27.9 billion expected by financial analysts polled by Thomson Reuters.

Net income was $1.4 billion, compared to a loss of $8.9 billion in the same quarter last year, when HP recorded a huge impairment charge for its acquisition of UK software firm Autonomy.

Excluding one-time items, HP reported earnings per share for the quarter of $1.01, down 13 percent from last year but again better than analysts had forecast.

The results gave a boost to HP’s stock. Its shares were trading 6 percent higher in after-hours trading Tuesday, at $26.51.

HP’s enterprise group reported a 2 percent increase in revenue, helped by increased sales of x86 servers and network gear, HP said.

The growth came at a price, however. HP’s x86 growth came partly from one big sale of “hyperscale” servers, which tend to yield less profit, and that contributed to a lower profit margin for the enterprise division as a whole.

Revenue from HP’s Personal Systems group dropped 2 percent. Consumer PC sales continued to decline, but its commercial business picked up by 4 percent, the company said. Pricing pressure lowered profit margins in the PC division as well, however, and PC sales were lifted by a single large deal in India.

That will make it hard for the PC group to repeat the strong performance next quarter, and HP expects the division to report a bigger decline next quarter than it did this quarter, said CFO Cathie Lesjak.

HP’s printing, software and enterprise services divisions all reported declining sales. But HP was happy with the printing division because it yielded higher profits, helping to offset the decline from servers and PCs, Lesjak said.

It’s been a tough year for HP. The PC market has been in collapse and its enterprise business has been floundering under what Whitman has called poor execution.

At one point, Whitman had said HP would return to growth in 2014, but in August she backtracked on that plan, saying revenue growth next year looks unlikely. There was no change in that guidance today: The economy remains tough, and the company still has to improve its “go to market” strategy, Whitman said, or the way it prices and sells products.

HP is taking several steps to get back on track, including the elimination of 29,000 jobs to cut costs. It has also said it will increase its spending on research and development, and it’s doubling down on products like its Moonshot hyperscale servers, 3Par storage gear and Vertica analytics systems, all of which HP says have big growth potential.

HP’s R&D spending actually declined in the quarter just ended, but Lesjak implied that’s because HP has cut its investments in Itanium and Unix products, both of which have shrinking markets. R&D spending will increase overall next year, she said.

The company is also cutting more jobs than it originally planned. The number could reach 34,000 by the end of this fiscal year, which ends next October, Lesjak said. That’s about 10 percent of HP’s worldwide workforce, and it will look for further headcount reductions next year, though Lesjak said most of the “low-hanging fruit” is gone.

In August, to address the challenges in its enterprise business, HP replaced longtime enterprise boss Dave Donatelli with Bill Veghte, HP’s chief operating officer and a former manager of Microsoft’s Windows Server business.

The results Tuesday may give customers and investors some hope. HP also announced that it will pay out a regular cash dividend of $14.52 per share on the company’s stock, the first of its 2014 fiscal year.

HP to combine its PC and printer divisions, report says

by admin ·

HP will make its Printing and Imaging Group a part of its Personal Systems Group, sources told the Wall Street Journal on Tuesday

Hewlett-Packard Co. is to combine its PC and printer divisions into a single business unit, a move that will see Vyomesh “VJ” Joshi, the longtime head of HP’s printer division, leave the company, according to a report published Tuesday.

HP plans to announce the move later today, according to a story in the Wall Street Journal’s All Things D blog, which cited unnamed sources. An HP spokesman said the company declined to comment on the report.

BACKGROUND: Whitman gives HP harsh report card, outlines recovery plan

It would be the first sweeping change at HP since former eBay chief Meg Whitman took over as CEO last September. Whitman was brought in to right HP’s ship after the company replaced two CEOs in a little over a year and appeared to lose its direction.

HP’s Personal Systems Group, which makes its PCs and laptops, is the biggest division at the company, puling in $8.9 billion in revenue last quarter. The Imaging and Printing Group, traditionally one of its most profitable groups, brought in $6.3 billion last quarter. Together, the two groups account for about half of HP’s total sales.

Under Tuesday’s reorganization, HP’s Imaging and Printing Group will be subsumed by its Personal Systems Group, and the combined division will be led by Todd Bradley, the executive vice president who today runs the Personal Systems Group, All Things D reported.

Joshi, who has been at HP since 1980, will leave the company, the paper reported.

Former CEO Leo Apotheker announced a plan last August under which HP might sell or spin off its PC division. It was a controversial move in part because of the uncertainty it created for HP customers, and Whitman was quick to announce after she came on board that HP would keep the PC group after all.

HP PC Spin-Off Puts Pressure on Microsoft to Nail Windows 8

by admin ·

Hewlett-Packard’s sale or spin-off of its PC business will put pressure on Microsoft to “hit the ball out of the park” with Windows 8, an analyst said today.

Computerworld — Hewlett-Packard’s sale or spin-off of its PC business will put pressure on Microsoft (MSFT) to “hit the ball out of the park” with Windows 8, an analyst said today.

“This is concerning no matter how you look at it,” said Wes Miller, an analyst with Kirkland, Wash.-based Directions on Microsoft, a research firm that specializes in following Microsoft. “HP has been a very strong partner of Microsoft for a very long time, so you have to ponder the change in its strategy.”

 

Best Microsoft MCTS Training, Microsoft MCITP Training at certkingdom.com

A sale of HP’s Personal Systems Group (PSG) is an indication of the decline in the importance of the PC — and thus Windows, which powers the vast majority of personal computers — in favor of other devices, including smartphones or tablets that run other operating systems, said Miller.

And that puts the heat on Microsoft to crank out another OS winner.

Slideshow: 8 Hot Features in Windows 8

“This re-emphasizes the need for Microsoft to hit the ball out of the pack with Windows 8,” Miller said.

Windows 8, which doesn’t yet have an official release timetable, will radically revamp the 21-year-old operating system’s look and feel and will run on tablets, Microsoft has said.

Earlier Thursday, news outlets, including Bloomberg and the Wall Street Journal, cited sources familiar with the matter who claimed HP would announce the spin-off of PSG later today during or after its quarterly earnings call, which is scheduled for 5 p.m. ET.

HP has confirmed that it is shuttering its webOS-based device business — including the just-launched TouchPad tablet — and looking at “strategic alternatives for its Personal Systems Group” that may include “a full or partial separation of PSG from HP through a spin-off or other transaction.”

“HP sees the future where the PC is not the focus,” said Miller, “just like IBM (IBM) did in 2005.”

Six years ago, IBM sold its PC Company Division to China’s Lenovo.

But a sale or spin-off of HP’s PSG — the world’s largest seller of PCs last quarter, according to Gartner — doesn’t mean the death of the personal computer.

“PCs will remain highly strategic because they run the apps that run businesses,” said Mark Margevicius, a research director at Gartner. “The fact that everyone is struggling [selling PCs] does not makes the platform any less strategic to business. PCs are a worldwide, 100-million-unit business. It’s not dying in any way.”

The PC sales attributed to HP won’t suddenly evaporate because the division is run as a separate entity, or sold to a rival, said Margevicius. “Ultimately, someone will own the business.”
