Its look like that IBM is not the one play in Blade server technology, the leading hardware industry such HP, DELL and SUN also take a part of it. Blade server claims as a green data center storage.
Virtualization is also the top news and now more possible to do it in blade technology.
Server virtualisation is rapidly gaining market acceptance for server provisioning. The introduction of virtual HBA technology will allow users to combine and leverage virtual servers and storage networks into flexible, secure and reliable solutions. The early generations of blades offered little synergy with virtualisation, but the convergence of blades and virtualisation is accelerating due to various factors outlined in this whitepaper.
“If the blades are completely diskless, that means they are booting via Preboot Execution Environment (PXE). This is probably the area where the concern lies due to the http-like nature of PXE. This environment, at least today, does not provide a way for detecting and disallowing unknown servers from performing remote installations. Because of this, one would follow the same best practices to secure the PXE as they would to secure their overall network such as:
* Physical security
* Firewalls
* Auditing and monitoring for intrusions
* Strong password protocols/procedures”
No more security issue in server, Blade server security is not unlike rack or standalone server security, but here you’ll find a few ways to ensure a secure blade server environment. As we know, data storage the first target for hackers, with blade server your network admin can take a rest any time they want.
Most of top brand server producer such as Dell, IBM, HP are now they talk about Blade server technology. A blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blades. This technology claims as a green technology, Each blade typically comes with one or two local ATA or SCSI drives.
Blade servers allow more processing power in less rack space, simplifying cabling and reducing power consumption. According to a SearchWinSystems.com article on server technology, enterprises moving to blade servers can experience as much as an 85% reduction in cabling for blade installations over conventional 1U or tower servers. With so much less cabling, IT administrators can spend less time managing the infrastructure and more time ensuring high availability.
By the way who is the first talk about this technology? and why blade server?
Blade server technology was initially developed in the early millennium through a partnership between IBM and Intel. Later, a number of major companies, led by IBM, formed an “industry community” in February 2006, with a website base at blade.org. The mission of the community is to “accelerate the growth and adoption of [blade] technologies in the market.” So, that is the reason why blade server?
Do I need to migrate to blade right now?
As customers look to grow their data centers or replace aging infrastructures, many are turning to blades to save space, increase density and decrease power consumption, while lowering total cost and improving infrastructure flexibility, blade server is the answer
The benefit of Blade server
The open BladeCenter design specifications are intended to enable companies to develop and build compatible networking switches, blade adapter cards (daughter cards), and appliance and communications blades. Hardware developers can now more easily develop and build compatible blade products in these categories and participate in the rapidly growing blades market served by the IBM BladeCenter and Intel Enterprise Blade Server platforms. Through the release of the design specifications, we can harness the development power of the industry and deliver a more comprehensive solution roadmap for our diverse customer base.
In the near future all of server should be like this, all are move to Blade server technology. The chassis and included blade servers may require a substantial initial investment in hardware and implementation for a business, even when compared to traditional rack-servers. However, blade servers bring advantages in space, power consumption, cable reduction, reliability, and economy of scale that may offer considerable longer term benefits.
1. You don’t actually need it — No, think about this. Vista doesn’t do anything you can’t already do with XP. About the only significant shift requiring Vista is DirextX10, but as no titles support it yet and, according to John Carmack (the godfather of modern gaming) there’s no need to yet either.
2. Cost $$ — It’s so blindingly obvious, most people will be blinded to it. You already have XP, and alternatives like Linux are free. If you really want to throw money away, go give it to a local charity.
3. On that note, it’s outrageously overpriced — at least in Australia. As revealed in the current APC, even after taking into account the profit margin Microsoft Australia previously applied to XP (as well as exchange rates, as you would expect), Australians are paying hundreds of dollars more for their copies than in the US. In fact, it’s cheaper for Australians to buy Vista direct by mail order from the States. If you think Microsoft Australia is reaming us, vote with your wallet.
4. Upgrading hardware — XP was demanding at release, but Vista more so. If you have an older machine that struggles with XP at the best of times, Vista is out of your ballpark unless you spend even more money to upgrade. If this is you, see point 1.
5. Driver support — Key hardware like video and sound is crippled at the moment — while Nvidia is working furiously to get a stable driver for the 8800 out by the 30th, there’s still no SLI support for any of the Nvidia range. And thanks to the removal of hardware accelerated 3D sound in Vista, Creative’s popular DirectSound based EAX no longer works at all, muting this feature for just about all gaming titles on the market today. Creative is in the process of coding a layer for its drivers to translate EAX calls to the OpenAL API which is seperate from Vista, but going by past experience with Creative drivers we won’t see these any time soon.
6. Applications that don’t work — there’s been plenty of coverage about applications that won’t work without a vendor update. These include anti-virus, backup and security software such as those from Symantec, Sophos and ilk; CD and DVD burning tools like the suite from Nero need updated versions to work; and even basic disk management and partitioning tools such as Paragon’s Hard Disk Manager are awaiting an update for Vista to be compatible. How many more will fail as Vista enters mainstream? Even Firefox has issues with Vista.
7. It’s a big fat target — with a new and untested in the global wild architecture, virus and malware authors are going to work overtime exploiting the holes Microsoft missed. In fact it’s already happening. Loath though I am to use the word ’security’ and ‘Windows’ in the same sentence, Windows XP has at least been patched to the hilt and can be used with a plethora of reasonably effective security tools that work now, without waiting for an update down the track.
8. UAC — Oh yes, the Microsoft solution for an operating system where mutli-user was an afterthought. Sure, you can disable it, but the OS then makes it clear then that the onus is on the user for any damaging programs that got to run with permissions, rather than with Windows in the first place. If you do have it on, it is going to annoy the hell out of you. It pops up far too frequently, and even on a fast PC, the UAC screen takes too long to come up and disappear.
9. DRM — And to a lesser degree TPM — were made for the RIAAs and MPAAs of this world, and the even tighter integration of copy protection mechanisms and ‘Windows Rights Management’ into vista are nothing more than a liability to you, the user. This ComputerWorld piece says is succinctly: ‘it’s hard to sing the praises of technology designed to make life harder for its users.’ As for TPM, this short animated video shows just how far the rabbit hole goes. And to think you pay for the privilege of having the use of media you purchased and own dictated by third parties, even on your own system.
10. The draconian license — somehow, Microsoft has forgotten that it built its business from products that empowered its customers, not hampered them. Of course, we forget that Microsoft’s customers aren’t you and I, afterall (see point 9). Aside from the backward thinking that is licensing, and not actually owning, your software new terms with Vista include being able to transfer the license only once; half the limit compared to XP for Home Basic and Premium on how many machines can connect to yours for sharing, printing and accessing the Internet; limits on the number of devices that can use Vista’s Media Center features; activation and validation governing your ability to upgrade hardware and use Windows itself; and outlawing the use of Home Basic and Premium with virtualisation software, and Ultimate only if DRM enabled content and applications aren’t used. But then again, who reads these anyway?
A blade server is a server with several apartments’ slim chassis, modular, electronic circuits, known as the blade server. Blade servers are to allow more energy treatment in less than rack, which simplifies the wiring and to reduce energy consumption. SearchWinSystems.com According to an article on the server technology, the company on the blade servers can offer so much experience that 85% discount on the wiring for the blade in comparison to the facilities or 1U server round. With less than cabling, administrators can spend less time with the management of infrastructure and more time in order to achieve greater availability.
Blade servers are self-server computing, designed for IT-High-Density. Whereas a rack-mount server can do it with (at least) a power cord and network cable, blade servers have removed many elements for space, power and other considerations, taking into account all elements to be functional as a computer.
A blade server is often described as a high-density servers and is usually in a group of servers, which has become a unique task, such as: • File Sharing • use of the Web page and caching • SSL encryption for Web Communications • The transcoding content of the web page for the small screens • streaming audio and video Like most requests for reunification, the blade server, may also be to support the load balancing and failover capabilities. That is the reason why blade server
