    Cable problem is fixed and still bad sustained write performance, so I have no doubts now that they are SMR, even as single drive write performance decreases after a while but like mentioned it's much more noticeable in a raid config, I have a 4 disk raid5 btrfs pool with theses disks, and transferring a large number of large video files (from a fast SSD pool) speed starts at around 300MB/s which is about what I expected, but after about 30 or 40GB transferred (maybe they have a small CMR zone?) it tanks to around 30MB/s and stays like that for the duration, I have other raid pools with CMR disks and transfer speeds remain consistent for the whole tranfer.

  4. You don’t need to have a massive media library or even a home lab that makes your dread your power bill every month to appreciate a fast network connection. The technology has finally dipped into the affordable range for many of us. If you are interested in experimenting with virtualization, iSCSI block storage, editing or even moving your gaming collection off your main drive – a high bandwidth connection to your other machines or servers just makes sense. We used a lot of QNAP gear in this project, there are of course other options. The ease of use and cost of the components used here though made for a great and cost effetive experience.

    Sorry for the late reply, but yes, you were right, these disks are definitely SMR, I have a few of them and it's especially noticeable on a btrfs raid5 pool, writes start fast enough but after a few GB transfer speed tanks. Turns out I had a cable problem with one of the disks, so the performance issues might be related to that, let me test some more and I'll post an update later.
  6. Last week
  7. The production of 1z nm technology marks the development and mass production of the industry’s smallest feature size DRAM node. Micron’s new 1z nm 16Gb DDR4 is said to deliver higher bit density, performance enhancements, all the while coming in at a lower cost than 1Y nm node. The new technology is more proof of Micron’s strive to innovate in performance and power consumption for its compute DRAM (DDR4), mobile DRAM (LPDDR4) and graphics DRAM (GDDR6) product lines. The power and performance improvements in a smaller package will be ideal for emerging technologies like AI, autonomous vehicles, 5G, mobile devices, and gaming.

  8. Probably SSDs will come, but they're still expensive and for the large block sequential type workloads most of these do, HDDs still are pretty respectable. I see these Lacie drives all over the place, especially in tech-havens like SanFran. They still hold a lot of mindshare with creative pros.
  9. The Dell Ultrasharp 34 Curved USB-C monitor is an elegant and streamlined piece of technology with a niche in the monitor market due to it’s ultra wide display, accurate colors, and USB-C. The monitor is aimed at creative professionals who do photo and video work. It offers multiple avenues of customization through accessories and software to satisfy users in any given environment. There are multiple mounting options with a provided stand and VESA holes. The Dell display manager adds another layer of useful customization. It manages the basics you’d find with any monitor and more advanced functions like easy arrange which allows you to customize your workflow and input manager to easily manage the PIP/PBP mode.

  10. I suppose these devices would be used for field video backups, but doesn't Seagate have any SSD availability? A 2+ lb. dual hard drive array seems rather old fashioned in 2019. SSDs would be so much smaller and lighter and not require all that heavy/bulky protective casing. I wonder if they are working on that.
  11. Let’s jump right into the big enhancements. Update 3 enables support for multiple NVIDIA GRID virtual GPUs (vGPU) per virtual machine. With several workloads now being graphic and compute intense, users will be able to easier run them in vSphere leading to performance increases and the speeding of jobs such as machine learning. The other big enhancement being the support for 2nd generation AMD EPYC processors. These new CPUs are already proving themselves in the performance arena as well as other benefits they offer. VMware goes on to state that the update to vSphere 6.7 will also provide performance enhancements to VMware vSAN. VMware Announces vSphere 6.7 Update 3
  12. Applications are changing. A large driving force of this change is microservices and the predominant deployment method for them, containers. While containers were originally designed for stateless applications, the need for storage persistence, has changed how containers are used. With this in mind, VMware has added container-ready infrastructure to the latest update to vSAN 6.7. VMware Announces vSAN 6.7 Update 3
  13. The Lacie Rugged Raid Shuttle is a new product that offers RAID desktop storage with the same ease of use as a traditional external hard drive. It is an extremely durable, high capacity, universally compatible solution for transporting large data files. The toughness of the design is essentially life proofed with drop, shock, water and dust resistance. There’s not much you have to worry about with this device. Using the provided USB cords the drive can be bus powered and transfer data up to 250MB/s. The drive comes in an 8TB capacity. Lacie Rugged Raid Shuttle Review
  14. Not really, unfortunately. Only with board rev 2.xx, which is not even released yet. No idea, how this provides "existing customers on the H11 gen systems a fast upgrade track" (quote from https://www.supermicro.com/en/pressreleases/supermicro-now-offering-amd-epyctm-7002-series-processor-based-systems-customers-who), as existing customers will certainly not have a rev 2.xx board. :-(
  15. The latest capacity of the Seagate IronWolf Pro line is a solid addition to the company’s Guardian Series. This NAS-specific drive gives users the highest capacity possible at relatively inexpensive price tag, while results from our performance charts reaffirm that the line is a good choice for SOHO, SME markets and creative professionals. Though it has many of the same features as the non-Pro line, the IronWolf Pro offers some expanded specs including its support of up to a 24-bay storage device (compared to 8 bays for the non-Pro version) and 1.2 million hours MTBF (compared to 1 million MTBF for the non-Pro version). Seagate IronWolf Pro 16TB NAS HDD Review
  16. How exactly are the 16TB EXOs different from the Iron Pros? I assumed the EXOS hardware was better to earn the higher MTBF and write ratings, but the performance seems somewhat worse. :( Which would you buy?
  17. Earlier
  18. All the comparison drives were other Seagates, in 14 or 16 TB. Perhaps some HGST, WD, and Toshiba 14s for comparison? Any update on the Toshiba 16 TB? It was announced months sooner, but I've yet to see it anywhere.
  19. Seagate has released its largest HDD, 16TB, with the Seagate Exos X16. A 3.5” form factor, the Exos X16 is stated to supply up to a third more petabytes per rack compared to 12TB drives, making it ideal for hyperscale applications/cloud data centers, scale-out data centers, Big Data applications, and distributed files systems such as Hadoop and Ceph. Seagate leverages a helium sealed construction to not only help hit the higher capacity, but to lower power costs as well as lower weight being sealed versus screwed shut (a small amount adds up in a rack). The drive comes with a 5-year limited warranty. Seagate Exos X16 16TB HDD Review
  20. The cheapie SSDs often have very little RAM or use the 4-bit/cell flash and perform quote poorly in writes. Make sure that your enclosure and host support UASP if at all possible.
  21. Amazon lists five key tools that Amazon Web Services Lake Formation provides: source crawlers, ETL and data prep, data catalog, security settings, and access control. All of these tools are managed through a central Lake Formation Console. Other AWS services like Athena, Redshift, and EMR will still be able to access data once it has been moved over.

    Swapping Out For Larger Drives

    IIRC you can do it in the management software but would have to rebuild after replacing each single drive (or each two drives for RAID 6). And then do an expansion once you finish the last rebuild with all drives replaced. It's quite a task. Much easier to get access to another card and build a new larger array then transfer the data.
  23. AMD launched its second generation EPYC 7002 yesterday and the processors have already demonstrated their capabilities in the first review we completed leveraging a GIGBYTE server. The new CPUs have up to 64 “Zen 2” cores and deliver a comprehensive set of I/O, memory and security features as well as bring the support for Gen4 PCIe. On that last note, Samsung is announcing support for its new PCIe Gen 4-enabled PM1733 SSD. The PM1733 is said to have double the throughput capabilities of current Gen 3 SSDs, which would make it the highest performance SSD on the market. For performance the drive would be able to read sequentially at 8.0GB/s and randomly at 1500K IOPS. Samsung Announces SSD & RAM Support For AMD EPYC 7002
  24. The new H12 A+ server family, that leverages the 2nd gen AMD EPYC processors, are stated to deliver up to twice the performance with double the core count compared to the 1st gen AMD EPYC servers. The new line also shows improved GPU accelerator performance and 4x the peak FLOPS per socket. The Supermicro H12 A+ servers support PCIe 4.0 and a large memory footprint, up to 4TB per socket of DDR4 3200MHz. The new line offers a nice balance of I/O, memory, and security capabilities.

  25. The TS65-S8036 comes equipped with 16 DDR4-3200 DIMM slots, 12 front-access hot-swap 3.5” and 2 rear-access hot-swap 2.5” drives, while featuring 12 front bays pre-configured to support up to 4 NVMe U.2 drives. In addition, the S8036 motherboard features expansion and storage options with 2 NVMe M.2 ports, up to 12 PCIe 4.0 NVMe, and 20 SATA ports in an EATX form factor. TYAN AMD EPYC 7002 Series Processor Based Server Platforms Announced
  26. The architecture of the second-generation AMD EPYC is all about performance. It is the world’s first high-performance x86 7nm server CPU. AMD has claimed to improve the CPU core execution engine over the original “Zen” core. Additionally EPYC Rome has twice the density, 1.25x the frequency (at the same power), and uses half the power (at the same performance of the previous model). AMD goes on to state that there is more on-chip bandwidth in all compute modes. The new CPUs also have high memory speed and bandwidth with a maximum theoretical memory bandwidth of 410GB/s (45% higher than Intel Xeon 2nd gen Scalable CPUs). AMD EPYC Rome 7002 Series Launched
  27. The new AMD EPYC 7002 CPUs are out, and the first server with the new processors (in our Lab, anyway) is the GIGABYTE R272-Z32. This 2U general purpose server uses the MZ32-AR0 motherboard, making it compatible with a single new EPYC Rome processor. The server has 16 DIMM slots, with a potential total of 1TB of DDR4 3200MHz RAM. The R272-Z32 has 24 hot-swap bays in the front for all NVMe storage, with two bays in the rear for SATA SSDs or HDDs. If customers need to added PCIe devices (including Gen4 devices now), there are seven slots in the rear, although only three are open. The server also supports AMI MegaRAC SP-X for BMC server management. GIGABYTE R272-Z32 AMD EPYC Rome Server Review
  28. Lenovo's choice of name for their new servers is interesting. Lenovo already has a ThinkSystem SR630 and a ThinkSystem SR650, but they both use Intel CPUs, not AMD CPUs like the new SR635 and SR655 server platforms. It looks like Lenovo is offering parallel systems running Intel and AMD processors. That they would go to the expense of duplicating their server lineup like that shows how far AMD has come since Intel CPU development slowed down. It is even more surprising since Lenovo acquired IBM's Intel-based server business just a few years ago in 2014. Lenovo Releases Servers Running New AMD Rome 7002 Series CPUs
  29. Breaking a record can be as simple as getting past the previously established numbers. HPE didn’t just move past existing records, it shattered them. For database virtualization, the DL325 and DL385 blew past the old record by 321%. In Power efficiency, the EPYC equipped server beat the previous record by 28%. Numbers like these are sure to get the attention of any organizations looking to improve virtualization, cloud, enterprise infrastructure and data-intensive workloads. HPE ProLiant With AMD EPYC Rome Breaks Several World Records
