Storage Comparison

ConnectingBlox provides solutions for any storage need - from single hard drives to complex storage networks.

Direct Attached Storage (DAS)

DAS subsystems are drives and/or arrays connected directly to a computer. Even the hard drive in your desktop computer is considered a DAS device. StorageBlox focuses on server storage so our DAS devices are typically high-performance RAID units designed for connection to a single server. With a simpler I/O process, DAS typically delivers higher performance that other storage technologies. That makes DAS best suited to dedicated servers with high storage demands.

Network Attached Storage (NAS)

NAS devices are very simple networked storage. These devices contain their own operating system and do not require a server - they are stand-alone systems which provide shared file storage. If you just need a place for users to store and share their files, NAS may be the best choice. NAS devices typically require less infrastructure, less administration and have a lower cost per gigabyte.

Storage Area Network (SAN)

SANs are complex storage systems designed to be shared among multiple servers. In a SAN, there is a storage device which connects to serves via a network switch. SANs can use specially designed networks such as Infiniband or Fiber Channel or they can be built on top of typical IP-based networks (iSCSI). SANs can produce performance equal (or even better than) DAS, but cost per gigabyte can grow exponentially to achieve such performance. SANs have excellent failover and redundancy options and are very well suited to virtualized environments.

StorageBlox Configurations

ConnectingBlox can design a StorageBlox device for your exact needs. Click on the tabs below to learn more about our configuration options.

  • Interface
  • Drives
  • Form Factor
  • RAID

StorageBlox devices can be built with a variety of drive interfaces. Note that this connectivity does not apply to NAS devices as they are ALWAYS attached directly to your existing network via standard ethernet.

  • SATA-2 (3GB/s) (DAS Only)
  • SATA-3 (6GB/s) (DAS Onl)
  • SATA-3.2/Express (16GB/s) (DAS Only)
  • eSATA (DAS Only)
  • SAS-1 (3GB/s)
  • SAS-2 (6GB/s)
  • SAS-3 (12GB/s)
  • Fiber Channel (4GB/s-16GB/s)
  • iSCSI (1GB/s-40GB/s (SAN Only)
  • Infiniband (SAN Only)
  • FCIP (4GB-100GB) (SAN Only)

We can also help with port multipliers and the complex cabling choices required to connect external storage units to your existing servers.

StorageBlox devices utilize ONLY drives from major manufacturers which have been put through a rigorous testing process to ensure enterprise-class performance and reliability. Devices can be configured with traditional magnetic hard drives, solid state drives (SSD), hybrid (part magentic and part SSD) drives or any combination:

  • Enterprise SATA
  • Enterprise SAS
  • Nearline SAS (Magnetic only)
  • PCIe (SSD only)

When using SSD, most configurations utilize MLC (multi-level cell) flash, but for higher performance and longer lifetimes we can also configure devices using SLC (single level cell) flash. SLC is better suited to extreme performance needs and applications with unusually high write operations. Since SSD writes data by applying voltage to a cell, cells deteriorate as data is written to them, this causes SSD to be less reliable over time than magnetic drives, but SLC deteriorates much slower than MLC, bringing them closer to the MTBF of magnetic drives. The trade-off for this higher speed and improved reliability is a considerably greater cost for SLC over MLC. Some vendors are now offering TLC (triple level cell) drives, but beware - while offering higher densities at lower costs, TLC drives amplify the reliability issues of MLC and will fail much faster than any other SSD technology.

StorageBlox devices can be built with virtually any form factor you require. We offer towers, rack mount and even mini-PC cases with up to 60 drives per case. Port multipliers can be used to expand our units even beyond 60 drives.

StorageBlox devices use top-quality RAID controllers and HBAs from manufactures like PMC (Adaptec), LSI, Atto and QLogic. Our systems can be configured for virtually any RAID level - including mixed levels to support different computing needs in a single device.
