Meeting the capacity demands of the datacenter is an ever-increasing challenge as cloud storage has become more commonplace. Storing cold and archival data is a relatively simple proposition, as old technologies become more refined and new technologies are rushing in to provide economical storage options for administrators. The problem with archival data storage comes into play when administrators are tasked with keeping data available within tight SLAs.
Keeping large amounts of data easily accessible requires higher capacity HDDs that operate within tight power consumption envelopes. Power consumption is the highest ongoing expense in the datacenter, and simply adding in more HDDs to address capacity requirements isn't the best option.
The Seagate Enterprise Capacity 3.5 v4 addresses capacity concerns within a reasonable power envelope, and even offers enhanced sleep states to help combat excessive power consumption. The increased capacity of the Enterprise Capacity v4 also offers a slip-in 50% capacity increase for those already using 4TB HDDs. This alleviates the previous requirements for new chassis, servers, racks, and accompanying floor space, to increase capacity.
Random workloads are increasingly addressed with SSDs as more robust tiering and caching schemes become available. Even though SSDs can provide the fastest non-volatile data tiers, the Seagate v4 also offers increased random speed that scales well in RAID environments. The Seagate v4 displays particularly good scaling in random read and write workloads, and handles mixed data well. Enhanced vibration tolerance also delivers performance consistency.
The Seagate v4 delivers an increase in random speed, but a few SSDs can easily outpace small HDD arrays. For many deployments, the flash tier handles random data, and caching and tiering mechanisms rely upon the HDD tier to satisfy sequential data performance requirements. SSDs can also provide impressive sequential speed, but SSDs aren't often placed into large arrays that benefit from enhanced parallelism, and wear is always a concern. The Seagate v4 comes with a boost in sequential speed, and we reached 1,697 MB/s with only eight drives during our sequential read tests.
The inclusion of RAID Rebuild technology can also speed recovery of arrays in many circumstances. This is an important consideration as we begin to see higher capacity HDDs enter the datacenter.
High-performance SSDs have pushed RAID controller manufacturers to develop exceptionally fast controllers, and these benefits extend to HDD arrays as well. The Seagate v4's delivered nearly linear scaling in most workloads, and simple extrapolation can provide a guideline for users who plan to deploy larger arrays. The Seagate Enterprise Capacity 3.5 v4 provides all of the expected enterprise-class features, and 12Gb/s SAS and 6Gb/s SATA products address nearline and high-availability requirements.
