Samsung Starts Mass Producing an SSD With Monstrous 30.72TB Capacity (betanews.com) 158

Brian Fagioli, writing for BetaNews: Samsung says it is mass producing a solid state drive with monstrous capacity. The "PM1643," as it is called, offers an insane 30.72TB of storage space! This is achieved by using 32 x 1TB NAND flash. "Samsung reached the new capacity and performance enhancements through several technology progressions in the design of its controller, DRAM packaging and associated software. Included in these advancements is a highly efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package, enabling a greater amount of space within the SSD to be used for storage. The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD," says Samsung.

          No, but a lot of folks in enterprise will not by it based on its price compared with spinning rust. You can afford to spend a lot of time structuring your databases and similar so that frequently accessed data stays warm in a cache and still come out cheaper than the price of moving all your company's data to SSDs.

            The extrapolated cost of this 30TB drive is less than the burdened monthly cost of a single engineer. Furthermore, if disk I/O is your bottleneck, then moving your DB from HDD to SDD is likely to give you far more speedup than fiddling with your schema.

              And if your company is small enough that a single 30 TB SSD is enough to meet your entire storage needs, then you probably aren't big enough to be so desperate for speed that you would buy a 30 TB SSD. I'm expecting most of these will be used for the most frequently accessed data for companies that are Google-scale, not companies whose total data capacity needs are rivaled only by my home RAID array. :-)

              But "fiddling with your schema" so that tables that get hit frequently are indexed on SSDs or DRAM drives (and, if necessary, stored in their entirety on those drives) means you get most of the speed win without the expense of storing your *entire* data collection on an SSD. The more you can separate out the frequently accessed data from the rarely accessed data, the easier it is to keep your costs sane. And the bigger your total storage needs, the more that design decision matters.

We have quite a bit of database data that we need to keep around for archive purposes that are almost never used again, but in the end the relative savings of HDD vs SSD in a relatively expensive storage unit that still needs backups etc. and the resources to partitioning and archive things it didn't add up so we're all SSD now.

            In my experience running IT for a large department the cost saved in not having to replace drives, and worse, restore data is worth the cost of SSDs, probably just in labor costs but also the additional peace of mind.

            Also:
            "For most corporate workloads, the acquisition cost of flash storage is still significantly greater than for HDD storage. However, when operating costs are factored in, the TCO for SSDs may actually already be lower than for equivalent HDD arrays. Use of SSDs reduces data center costs for power, cooling, floor space, rack space, and maintenance. And as SSD purchase prices continue to fall, the TCO disparity can only grow greater over time."

However, the price for SSD storage is at the point that the advantages (performance, density, and reliability*) outweigh the price difference. You can get enterprise SSD solutions for under $0.30/gb from multiple vendors. At some point it's cheaper to go SSD than to invest in "spending a lot of time" trying to make it faster on HDD.

        I'm not sure the HBA is really the problem. I mean, you want I/O offload to some other CPU for RAID and logical disk management and some kind of physical disk channel multiplexing.

        There's no reason these things are inherently slow unless you're buying low end stuff. Obviously you'll get better raw I/O with direct NVMe off the PCIe bus to the CPU, but as soon as you get into RAID it gets more complicated. Either you use software RAID at the OS level or you have to add a RAID controller to your PCIe bus.

        • The HBA itself isn't a problem. No individual piece of such a setup is. But the cost of the HBA and cables, dealing with cable routing in the rack, handling risers and chassis slot compatibility, etc. only to then have to deal with an external box (perhaps 2 for redundancy) that gives you less performance than you could get with direct attached storage is overall shitty.

          If an HBA has its own PCIe bus, so can a RAID controller. There's no fundamental advantage there. The thing about software RAID is that

                For you youngsters, back in the day, there were no tower cases, you stood a desktop case on end. In addition, you had to run a "low level format" to physically mark the sectors on the drive, as well as mark the sector interleave. If you were running the drive vertically, instead of horizontally, you got better performance when you low leveled it in the vertical orientation.
