"Virtualisation is key," he said. "We need to separate the brain [control unit] from the media and update the 'intelligent' part of the process. HDS has kept the disk separate from the control unit - universal storage platform as opposed to other manufacturers - since 2005. HDS also offers non-disruptive data migration services, Storage Reclamation service, assessment tools and services to gauge reclamation potential, as well as Switch IT On IIIe."
On Yoshida's 15 February blog, he said: "The adoption of new technologies is essential to improve performance and availability, and stay competitive. Still, migrating to new storage technologies presents significant challenges since it involves data and applications, as well as people and processes. Detailed and careful planning must be done to ensure business priorities, data protection, and application data requirements are all incorporated."
"As storage systems get larger and support more applications, the migration of storage from one generation to the next becomes more disruptive, expensive and riskier," he said.
"David Merrill, who tracks this on a regular basis, estimates that the burdened cost of doing a migration today is about US$15,000 per terabyte, which is more than the purchase cost of the capacity. The two biggest concerns that organisations face during a data migration are the risks of downtime's impact to the business and budget overrun. In a recent survey, 70 percent of participants reported schedule overruns of 30 percent while 64 percent reported average budget overruns of 16 percent."
Yoshida added that adopting an efficiency campaign involved reviewing people, processes as well as the above mentioned technology services but could realise a recovery of a conservative 40 percent of storage. "The technological approach also involves active archiving, saving energy from using smaller factor drives and page level tiering of data."
HDS' Khoo added that according to a survey on migrating to new technologies by market research firm TechValidate, 70 percent of businesses reported schedule overruns and 64 percent reported budget overruns.
"With overall storage migration costs exceeding US$15,000 per terabyte, organisations are under increasing pressure to identify and adopt best practices to lower their IT operating expenses and redirect savings in support of new investments. Leveraging proven Hitachi migration methodologies, non-disruptive migration uniquely enables host-transparent storage migration that allows IT organisations to mitigate the outage window due to data migrations and reduce risk and expenditures."
"In today's business climate, organisations need to accelerate innovation and reduce operational expenses to increase their competitiveness," said Khoo. "Only HDS provides the migration capabilities to eliminate downtime while dramatically reducing the risks and costs associated with adopting new technologies. The key to achieving this capability is that virtualisation, specifically our proven Hitachi controller-based storage virtualisation, is at the core of our new service and gives us distinct advantages in efficiency and cost effectiveness.
