Earlier this year, Yoshida voiced concerns about effective monitoring of MAID disks during idle periods, although the exec says that HDS has resolved this issue with its PSSS. "We check [the disk] when it is idle, and we check it when it spins up as well."
Long-term, PSSS is unlikely to find its way into the vendor's high-end Universal Storage Platform (USP). "I don't think that you would want to do anything like this on USP, because that is primary data that typically shouldn't be idled," says Yoshida.
Although HDS has not yet released its PSSS pricing, Yoshida says the vendor will use a software "key" to enable the service on its AMS and WMS device. Pricing for the key will not depend on storage capacity, and HDS will instead charge a set fee per device, according to the exec.
