The 7450's deduplication also helps the system scale to higher capacity than arrays from startups can achieve, because most startups handle all their deduplication in memory, according to HP. The 7450 can take in 460TB and deduplicate it without incurring a speed penalty, Nunes said. After deduplication, the array ends up with 1.3PB of effective capacity.
HP's array also takes up much less space than some competing systems, the company says. An EMC VMax with 250TB of usable capacity would consume three standard data-center racks, while the HP 7450 would take up just 4U (7 inches or 18cm) of space in one rack, Nunes said. The EMC platform would also consume up to eight times as much power, he said.
The new SSDs that give the 7450 higher density use mass-market cMLC (commercial multilevel cell) flash, a grade that's less expensive than enterprise flash. Despite that, HP is offering the HP 3Par Get 6-Nines Guarantee, assuring users of 99.9999 percent uptime, as well as a five-year SSD warranty. That level of availability implies just over 30 seconds of downtime per year.
The SSDs are set to ship later this month for a U.S. list price of $14,315. The updated software for more efficient deduplication and other features will be available free to all 7450 customers in September, HP said.
