ClearSky Data came out of stealth today with a managed service for primary storage consisting of on-premises appliances for hot data, the vendor's data centers for the majority of storage and Amazon Simple Storage Service (S3) for data protection.
ClearSky calls its tiered storage a global storage network, and promises low latency from a customer's site to one if its point of presence (POP) data centers.
The on-premises edge appliances are 24-slot dual controller all-flash systems that use 1 TB self-encrypting solid-state drives and run in dual-node active-active clusters. The appliances include ClearSky data deduplication and caching algorithms and connect to the nearest POP over Gigabit Ethernet. To protect data in the regional data centers, ClearSky Data writes customer information again to object storage in Amazon S3.
CEO Ellen Rubin said ClearSky's POPs will always be within two milliseconds of its customer site, and can provide hundreds of thousands of IOPS. ClearSky is launching with POPs in Boston, Philadelphia and Las Vegas with plans to expand in the U.S. and internationally. The eventual goal is to have a POP within 120 miles of any customer.
