Samsung wants to reduce core counts in storage servers with new SSDs

At this week's OCP Global Summit, Samsung disclosed more information about a new type of solid-state drive (SSD) it's working on - one that only makes sense in a data center context, for now.
When it comes to flash memory, the most common configuration in data centers worldwide is JBOF (or just a bunch of flash), which uses NVMe SSD storage attached to PCIe switches, processors and NICs (network interface cards). There are two rather significant issues with this system, to do with the lack of scalability of the storage controller and limited bandwidth; a classic case of too many middlemen. EBOF - or Ethernet SSD Bunch of Flash, as Samsung puts it - aims to solve this issue by putting the Ethernet ports (two of them for redundancy) on the SSDs themselves.
Check out our list of the best portable SSDs available Heres our list of the best external hard disk drives of 2020We've built a list of the best-rugged storage out there these are not your usual Ethernet ports, however, as each supports a staggering 25Gbps - about 25x what most Gigabit interfaces can achieve. Unsurprisingly, that's only available in a standard SSD (i.e. 2.5-inch), rather than the smaller M2 form factors.
Samsung claims the E-SSD drive will achieve PCIe Gen4x4 performance or about 1500K IOPS at 4K random read. What’s even more spectacular, though, is that the performance of the drive scales in an almost linear fashion.
Based on the chart provided by the company, 24 NVMe drives will be about 7.5x faster than a single NVMe drive, whereas the same number of NVMe-oF SSDs will be about 23x faster than a single drive. Samsung reached out to point out that the graph is not linear and not to scale. A spokesperson for the company added, "we have no specific data to publicly share at this time, but will say as we noted originally that the numbers you stated are not the numbers that we have".
Removing the CPU, networking and other bottlenecks means lower latency, higher bandwidth, lower cost, better performance and potentially big TCO savings. Samsung added that "EBOF will be helpful to many in hardware procurement including networking vendors and OEMs".

SK hynix PE6011 Enterprise SSD Review

We last discussed SK hynix back in August as we looked into the history of the company and overviewed their Enterprise SSD solutions. Today we are reviewing and looking at the performance of the SK hynix Enterprise SSD the PE6011. The PE6011 features a U.2 7mm form factor, 3D TLC NAND, PCIe NVMe interface, and capacities up to 7.68 TB. It is ideal for read-intensive workloads and light write usage. What’s unique about this product is that from conceptualization to manufacturing everything is done in-house by SK hynix. This product is aimed at those looking for an economical PCIe solution for the datacenter environment. Looking at the design and build of this drive, the entirety of the casing is a polished silver. It is a 2.5″ drive with a U.2 connector and a form factor z-height of 7mm. Being 7mm lends a physically smaller footprint and gives this drive the ability to be equipped and fit in a large variety of things for universal appeal. Branding as well as unique identifying informa...

Kingston DC1000B SSD Review

The Kingston DC1000B is a read-focused M.2 NVMe SSD aimed at the market of on-board server boot drives. While the DC1000B is aimed at being a cost effective offering, it doesn’t skimp on features such as power-fail protection that buyers expect from enterprise-grade SSDs. Aside from being used as a boot SSD, the DC1000B is beefy enough and can be leveraged for caching and logging applications as well, with a 0.5 DWPD endurance rating and a 5 year warranty. The DC1000B ships in capacities of 240GB and 480GB. The DC1000B leverages 3D TLC NAND and the PCIe Gen3 x 4 NVMe interface to offer sequential read speeds topping 3.2GB/s. According to Kingston, the drive can hit up to 205K IOPS in 4K steady-state read at an average latency of 161?s. On the write side of performance, things are a bit lower, but this is expected. Top sequential write speed is 565MB/s, top steady-state 4K is 20K IOPS, and latency is only 75?s. In other highlights, the drive supports SED with AES 256-bit encryption. ...

Memblaze PBlaze5 920 Series NVMe SSD Review

We’ve seen numerous enterprise SSDs from Memblaze over the years, they’re often on the leading edge when it comes to both technology and performance. Recently they’ve launched a new set of SSDs in the Memblaze PBlaze5 family, the Memblaze PBlaze5 920 Series. The 916 Series before it, the PBlaze5 920 Series comes in U.2 and Add-in-Card (AIC) form factors. The biggest difference with the 920 Series is that it uses a new set of NAND, moving to 96-layer 3D TLC NAND from 64-layer in the prior model. At the top end, the new Memblaze SSDs are quoted to deliver 5.9GB/s and 970,000 IOPS at the top end of the performance spectrum. Memblaze PBlaze5 920 926 The 920 Series comes in two endurance ratings, either 1 drive write per day (DWPD) or 3 DWPD. This creates four distinct drives, segmented on form factor and endurance. The AIC form factors are designated as C920 and C926, with the C920 being the more read the centric drive and the C926 carrying that 3 DWPD endurance rating. Similarly, the U....
