As a unified storage system, the Jupiter Callisto 16TB 8-Bay NAS Server from OWC / Other World Computing can function both as a NAS (network attached storage) and as a SAN (storage area network) at the same time. Tackle most any data need from general document storage to video production with Ethernet speeds up to 10 Gb/s coupled with advanced data protection, optimization, and flexibility via Callisto's ZFS-based storage architecture. Mini-SAS expansion supports up to seven OWC Jupiter Kore storage racks and can be expanded into petabytes of managed storage from a single Callisto box.

OWC's Jupiter Castillo features a 2 RU form factor and is equipped with eight drive bays that support 3.5 and 2.5" SATA or SAS drives, although this model has 16TB of storage that is configured as 8 x 2TB SATA III 2.5" SSDs. It is driven by a 2.2 GHz Intel Xeon Silver 4210 10-Core processor and 128GB of 2666 MHz DDR4 ECC Registered RAM in an 8x 16GB configuration, which may be upgraded to 512GB. Network connectivity is achieved using dual 10GbE ports, while storage expansion is accomplished using two 12 Gb/s Mini-SAS 8644 ports that allow for four SAS-3 compliant channels. Additional connectivity includes 2 two USB-A 3.2 Gen 1 (3.1 Gen 1/3.0) ports and two USB-A 2.0 ports for direct/local system updating and mouse/keyboard support, a serial port, and IPMI 1GbE RJ45 port, and a VGA port for accessing Console Setup to determine the unit's management IP address if you're using a DHCP assigned IP address. For users who need RAID capabilities, the Jupiter Castillo comes configured as RAID Z1, but may be reconfigured as RAID Z2 or Z3.

OWC's Jupiter Callisto 8-Bay NAS Server operates using dual redundant 380W power supplies and the TrueNAS SCALE OS. It is compatible with systems running Windows 10 or later, macOS 10.15 or later, and Linux. Included are two power cables, two slide rails, two rail extensions, eight M5 pan head screws, twelve M5 cage nuts, and four M5 enclosure securing screws.

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 to Mac and Windows computers.

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

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.

When Gigabit won't do, you can use the built-in 10GBASE-T Ethernet interface for speeds up to 10 Gb/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 CAT 6a and CAT 7 copper cabling at distances up to 328' 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.

As your storage requirements grow, you can easily add up to seven OWC Jupiter Kore systems for a total of 2500TB (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.

Q: 8. Hi, can this product be used without plugging it to electricity? Or if no, can I use external battery?

A: The OWC ThunderBlade X8 16TB 8-Bay Thunderbolt 3 RAID Array (8 x 2TB) requires its included 90W power supply to function.

Q: 9. Does this NAS Index with MAC OS? what can be expected with locating and retrieving 25 TB worth of image files

A: If you are referring to Spotlight indexing, the Mac OS has that turned off by default, however it can easily be enabled with one command. The WD My Cloud PR4100 is fully compatible with the Mac OS, and once mounted will be just as accessible as a directly attached drive. Keep in mind that as this is a NAS you will be limited to the speed of your network accessing files.

Q: 10. Would this product work if a client is off-site but yet still wants access to media files? If so, what's the optimal upload speed out of our building for this to work at a reasonable speed?

A: With the correct configuration, this model can be accessed from off site. There is essentially no optimal upload speed, it will work at any speed, and as with any media speeds, the faster the better.
