Welcome to a laptop battery specialist of the Hp laptop battery
The PowerLinux machines have slightly lower base-system prices, much lower disk-drive prices (35 to 70 per cent lower per GB), and crazy lower memory prices (on the order of five to seven times lower cost per GB) for the exact same features in the plain-vanilla Power Systems machines that are enabled to run AIX and IBM i. That's how badly IBM wants to compete and how much of a threat it sees the x86 server racket to its Power Systems biz.
It would not be at all surprising to see IBM offer the double-stuffed Power7+ sockets it talked about back at the Hot Chips 24 conference in late summer in the PowerLinux machines first – and maybe only in the PowerLinux machines, if the workloads and competitive pressures map out that way.
The p260 node with Power7+ processors will be available on December 3. With 32GB of main memory and two of the four-core Power7+ chips running at 4GHz, the p260 node costs around $12,000.
Drilling into the pricing a bit, IBM wants $8,603 for the pair of four-core 4GHz processors. If you want to go with two eight-core 3.6GHz Power7+ engines, that will run you $15,409 just for the two chips, and two eight-core chips running at 4.1GHz will cost $17,524. It costs $100 with battery such as Compaq Presario V2000 battery (compaq v2000 battery ), Hp pavillion zx5000 battery (Hp zx5000 battery ), Hp PP2200 battery , Hp Pavilion dv2000 battery (Hp dv2000 battery ), Hp HSTNN-LB31 battery , Hp EV088AA battery , Hp Pavilion ZT1000 battery , Hp Pavilion XZ200 battery to active each core on the system, which is a lower fee than normal Power Systems machines have. That 1.8-inch SSD with 177GB of capacity costs $4,400 at list price, and a 32GB DDR3 LP memory stick costs $3,200 on this machine.
In a related announcement, IBM will be allowing the p260 to be an option in PureFlex infrastructure rack configurations (which include servers, storage, switching, and management software) starting on December 10. Up until now, only the two-socket x240 server node, which is based on Intel's Xeon E5-2600 processors, was available in this preconfigured infrastructure-cloud-in-a-box.
The PureFlex setups can now also be configured with the x220 and x440 server nodes that IBM announced and shipped in August using the low-end Xeon E5-2400 and the high-end Xeon E5-4600, respectively. IBM's announcement letters make it look like these machines are being announced today, but they are not. Go figure.
IBM has also made good on its promise of creating a variant of the Storwize V7000 block storage array that can slide into the Flex System chassis and plug into its power supplies, management controller, and integrated networking.
The Flex System chassis is a rack-mounted enclosure that's 10U high and can sport up to six 2,500 watt power supplies. It has room for seven double-wide and fourteen single-wide devices. The internal V7000 takes up the same space as two double-wide server nodes, and has room for two dozen 2.5-inch SAS drives.
The V7000 internal array has two "node canisters," which are subcomponents with controllers, cache memory, and disks hanging off them. (There are also "expansion canisters", which just have disks and hang off the nodes.) Each node canister in the internal V7000 has 8GB of cache, and has 8Gb Fibre Channel or 10 Gigabit Ethernet ports that can be used to link the array to the server nodes in a Flex System through the midplane in the chassis.
IBM is supporting a bunch of different SAS drives in the internal V7000. You can choose from 200GB and 400GB SSDs; 146GB and 300GB disks spinning at 15K RPM; 300GB, 600GB, and 900GB disks spinning at 10K RPM; or 500GB and 1TB disks spinning at 7.2K RPM.
A Flex System V7000 enclosure with the node controllers costs $14,500, and an expansion chassis in which to hang more drives off this controller costs $3,500. Disk drives range in price from $459 to $1,109, depending on capacity and speed. Those SSDs are crazy expensive, at $4,869 for the 200GB unit and $9,369 for the 400GB unit.
