Our eRacks/NAS72 is a high-storage-density 4U rackmount storage server with 72 removable drive bays with over 1.5PB (Petabytes) of storage with 22TB WD Enterprise-level 3.5-inch Hard Disk Drives, and 1.8+PB with 26TB WD SMR drives.


Cloudy Forecast

Suitable for Cloud Storage, OpenStack, SDS (Software-Defined Storage) with the leading Open Source SDS solutions, NAS/Local LAN usage, media libraries, or any number of other storage uses, the eRacks/NAS72 is a truly petascale solution - ten eRacks/NAS72 servers in a standard 42u rack gives you over 15PB (Petabytes) of raw storage - with 2U of room to spare for a UPS, KVM, Network switch/firewall, or other of eRacks' rackmount accessories.


Pre-configured, tailored to you

 In keeping with eRacks' signature service of saving you time and money by pre-provisioning your system to be as turnkey as possible, eRacks can preinstall and configure your server in one of several ways:

- Your choice of Cloud software is available, including OpenStack, CloudStack, Eucalyptus, OpenNebula, ProxMox, or other - just specify in the "Notes" field when you place your order or request a quote.

- Your choice of Storage or SDS software, to fit inro a larger architecture or pre-existing cloud infrastructure - choices include Ceph, GlusterFS, MooseFS (an eRacks Partner), LizardFS (Also ans eRacks Partner), or others

- Simply ask us for a quote, and specify your preference in the "Notes" field -

- Your choice of NAS software / OS is available on request, including Samba, EasyNAS, TrueNAS (formerly FreeNAS), XigmaNAS (Formerly NAS4Free), OpenMediaVault, RockStor, or your choice - if you don't see it, just specify it in the "Notes" field when you place your order or request a quote.  Configured by default with Ubuntu and Samba, the eRacks/NAS72 can act as a seamless NAS file server in a Windows or mixed environment.

- Or, you may choose one of our regular distros, and/or simply ask for your preferred OS, packages, and storage options - Arch Linux, LizardFS,Ceph, MooseFS,Samba,NFS, Novell, Apple and any other available configuration requests - just add it in the Notes.

This model is available with single or dual multi-core Xeon or AMD CPUs.

At full capacity, this system houses 1584 Terabytes (22TB x 72 drives) or 1872TB with 26TB WD SMR drives. Read our press releases.


 Greener on the other side

The latest larger Seagate and WD drives are Helium-filled - which require far less rotational energy, making them 23%+ more efficient - and the drives are also lighter (the helium helps, here!), meaning the packing crate has a lower shipping weight as well, saving money on shipping as well as on month-to-month electricity bills - a truly green solution.



Every Which Way

The default configuration is a half-populated (36 drives) config, to make it accessible at a lower initial price, and the storage can be increased later by filling the empty drive trays.

For cloud configurations such as OpenStack, CloudStack, Eucalyptus, and others, you may put the number of servers or desired architecture summary in the notes field (eg all-in-one, storage only, etc) or contact us directly for more involved configurations.

Note that other memory configurations, including other types and speeds of RAM are available, including DDR4 / DDR5, ECC / nonECC, etc - contact us for details and a custom quote.

Western Digital Gold, Red, Black, Green, Purple, or Re DataCenter drives are also available, email us for details, at

SAS drives and SAS RAID controllers are available with this system. Please email or phone to request a quote.
