Rack-scale systems that hold a data center's data and serve it to servers over a network or direct connection. Unlike a NAS appliance, they're sized in controllers, shelves and drive bays, and usually configured and quoted through the vendor.
What's the difference between a storage array, a JBOD, and a NAS?
A storage array pairs controllers, cache, and software (snapshots, replication, RAID) with its drives and serves block or file storage to many servers. A JBOD or expansion enclosure is just drive bays, adding raw capacity to a server or array that provides the intelligence. A NAS is a self-contained file-serving appliance, usually smaller-scale; browse those under the NAS category.
All-flash or hybrid storage?
All-flash arrays deliver consistent low latency for databases, virtual desktops and demanding virtualization, at a higher cost per terabyte. Hybrid arrays mix flash caching with high-capacity disks for a better price on bulk data with mixed performance needs. Match the media to the workload's latency sensitivity and capacity growth.
Is tape still relevant?
Yes. For cold archive and offline backup, tape remains the cheapest medium per terabyte, with media the LTO program rates for around 30 years of archival life and a physical 'air gap' that ransomware can't reach. Current LTO cartridges hold tens of terabytes. Disk and cloud handle fast restores; tape handles the deep archive tier and compliance retention.
Why do many storage systems show no price?
Enterprise arrays are sold configured, with controllers, shelves, drives, software licenses and support quoted as a package through vendor sales and channel partners, so makers rarely publish list prices. Where real pricing is published it appears here; otherwise click through to the vendor's configuration and quote page.
