I bet you didn’t know that this year, there are seven billion mobile devices being used on a daily basis. This mobile explosion has been the catalyst for the doubling of data created and consumed every two years. IDC shows that in 2009, there was 0.8ZB of data stored vs.35.2ZB predicted for 2020. This bring-your-own-device (BYOD) movement has led to the creation of massive amounts of unstructured data. The bulk — 70 percent of this data — falls into the segments of file and object storage.

All this data has to be stored and many companies are struggling to keep pace with the rising cost of storage expansion. To help with that, I’ve compiled a list of why customers should consider direct-attached storage (DAS) — specifically a JBOD device (Just A Bunch of Disks) for their growing storage needs.


Top 5 Reasons Why A JBOD Can Be Your JBUD

  1. I mentioned above that 70 percent of the data being created today is file and object storage. This means that the vast majority of data has a large footprint, but most importantly, is rarely utilized — indicating that the key parameter of a storage solution for this segment is cost/terabyte. I recently spoke to a customer in the medical industry who indicated that 65 percent of their stored data had not been accessed once in three years! Would you want to spend a lot of money to store data that is “cold” or “cool”?
  2. According to IDC, the operational cost of maintenance or administration tied to servers is an incremental 25 percent over their acquisition cost; however, for storage and networking, the incremental operational cost increase is 50 percent, which means that companies spend more on maintaining their storage infrastructure than their compute deployments. For this reason, as the data explosion continues, companies will look for the most economical way (lower acquisition cost) to support their growing data needs.
  3. While there are other storage technology protocols in the market, on average NAS and SAN solutions can cost 30 percent more per system than DAS JBOD solutions.
  4. With the advent of software-defined storage (SDS), customers can recapture value in their legacy storage solutions, while future-proofing new additions. SDS elevates the value of a JBOD by raising its aggregate features, functionality and value up to that of a NAS or SAN. If customers are struggling to keep up with data growth, and the operating expenses tied to storage are exceedingly high, a JBOD usage model coupled with SDS allows customers to recapture value in their existing storage installation, while making storage expansion more affordable.
  5. JBODs offer enterprise functionality through expandability, high-availability configurations, a wide range of connectivity options and increased manageability at greater dollar value. These features allow JBODs to be deployed into a wide range of verticals, as well as servicing a variety of compute workloads.

Lenovo has invested in the storage segment heavily, and the ThinkServer SA120 DAS is one example. The SA120 offers these key features:

  • Serviceability – All the drives have their own enclosures. For example, the 2U SA120 JBOD can support 12 3.5-inch drives (48TB) in the front and four additional 2.5-inch SSDs (3.2TB )in the rear. A data-center administrator only needs to perform services on the JBOD, which allows the host server to remain operational. The SA120 also supports up to two 550W hot-swap 80PLUS Gold power supplies and two hot-swap, redundant fans.
  • Performance – The SA120, coupled with ThinkServer host servers configured with LSI CacheCade technology and Intel SSD drives, provides additional cache, low latency and amazing IOPS improvements. The SA120 with its clever, scalable design provides an optimal tiered storage solution.
  • Manageability – With support for up to two I/O controllers in the SA120, a user is able to manage multiple JBODs (when cascading) via single host system. 
  • Scalability - A total of eight SA120 DAS arrays are supported off the primary solution.

I have seen customers deploying this solution for Hadoop and Lustre environments, as well as video surveillance, media-centric operations or as backup for distributed environments.
