OWC Jupiter Callisto

With 8 or 16 drive bays and two 10GbE ports built in, the OWC Jupiter Callisto is the perfect rack-mounted NAS. A secure, centralized powerhouse for file sharing for up to 100 or more users in commercial, enterprise, education, research and creative content environments.

Mini-SAS expansion supports up to seven OWC Jupiter Kore storage racks for up to 320TB, and can be expanded up to 2.5PB of managed storage from a single Callisto box.

Unified Storage icon

Unified Storage

As a unified storage system, OWC Callisto provides both NAS and SAN functionality on Ethernet networks. This means that Callisto can integrate easily into existing Ethernet-based storage networks, or can be the heart of a brand new storage infrastructure to provide iSCSI storage to a server or file sharing SMB/AFP to Mac and Windows computers.

Advanced Data Architecture

Utilizing ZFS storage architecture, advanced data management features come standard on OWC Jupiter Callisto:

  • Storage pools to ensure easy future expansion and optimal data usage
  • Caching to provide additional speed
  • Automatic data integrity management to prevent data loss
  • A robust set of RAID level options to ensure the best balance of speed and redundancy
  • Snapshots, replication, and clones for easy backup and recovery
  • Compression and data deduplication so data takes up less space

Straightforward Management

Jupiter Callisto's web-based management provides a straightforward interface to: configure storage, manage users and permissions, manage storage reallocation and expansion, monitor system health, and more.

10GbE Onboard with 40/100GbE Available

When Gigabit won't do, you can use the built-in 10GBASE-T Ethernet interface for speeds up to 10Gb/s while maintaining compatibility with 1GbE computers and hardware. Since Callisto provides 10GbE over 10GBASE-T ports (as opposed to SFP+ ports that require costly transceivers and cabling) you can utilize lower cost CAT6a and CAT7 copper cabling at distances up to 100 meters in a single run. Callisto does all that while maintaining compatibility with 1GbE networks, so you can upgrade computers to 10GbE as needed. With the option of adding 40GbE or 100GbE uplink interfaces, Callisto can support much larger network environments with drastically lower latency.

Easy Expansion icon

Easy Expansion

As your storage requirements grow, you can easily add up to seven OWC Jupiter Kore systems for a total of 2,500TB (2.5PB) of centralized storage without the need to migrate data or take the system down. Simply install a Kore system into your rack, connect it to your Callisto system via Mini-SAS, and with a few clicks in the management interface your new storage is ready to be utilized.
