Just days after NEC announced plans to ship blade servers based on Intel's Itanium 2 microprocessor, HP has confirmed that it too expects to ship blade systems based on the 64-bit chips.
HP revealed few details about its upcoming blade systems, but HP director of marketing for ProLiant Platforms, Sally Stevens, said that the systems would ship in 2005, and would use a different chassis from the ProLiant BL systems HP was currently shipping.
Blades are densely packed servers that are slid into a common chassis like books in a bookshelf. Though analyst expectations were initially bullish, blades have not sold as well as predicted.
For example, HP said it had sold 100,000 blade systems to date, and after halving its initial blade sales predictions, research firm, IDC, now expected about 450,000 of the servers to be sold in 2004, which would account for about 8 per cent of the server market.
Because Itanium systems consume a large amount of power - Intel's latest Itanium processors consume 100 watts each - and generate a lot of heat, they have typically not been considered appropriate for the densely-packed blade systems.
HP has not yet made a decision on what specific Itanium processor will be used in blades, but Intel is readying two new low-voltage chips designed for dual-processor systems, that could be appropriate.
Later this year, Intel will ship a 1.2GHz processor codenamed Fanwood. It will be followed in 2005 by a low-voltage chip called Millington, which is based on Intel's dual-core Montecito design.
By the time the Itanium blades ship, however, they will not be the only 64-bit blade systems sold by HP.
Later this year, the company plans to ship blade severs based on Advanced Micro Devices (AMD)'s 64-bit Opteron processor, a choice that HP was pushed into making because of the power consumption required by Intel's current line of Itanium processors, according to Insight 64 analyst, Nathan Brookwood, said.
With the new Itanium processors expected in 2005, however, Itanium power consumption should be reasonable, Brookwood said.
Because Opteron systems performed extremely well with 32-bit applications HP saw the Opteron blades as appropriate for customers who were focused on 32-bit software, but wanted to begin dabbling in the 64-bit space as well, Stevens said.
"If they want pure 64-bit performance, Itanium is the better path to go," she said.
While HP expected the Itanium blades to be used for 64-bit corporate and technical computing applications, the company was beginning to see demand from other vertical markets as well, Stevens said.
"We actually have retail customers that are interested in Itanium-based blades," she said.
Pricing and availability of the Itanium and Opteron systems was not available.
