HPE: Prevent Crash Bug By Patching Our SAS SSDs!

Hewlett Packard Enterprise (HPE) issues a support bulletin for customers of SAS SSDs from the company warning certain models can permanently fail after 32768 hours (or 3 years, 270 days and 8 hours) of operation unless patched.

As per the bulletin, the bug causes "drive failure and data loss at 32768 hours of operation and require restoration of data from backup in non-fault tolerance, such as RAID 0 and in fault tolerance RAID mode if more drives fail than what is supported by the fault tolerance RAID mode logical drive." HPE adds should the storage device fail, "neither the SSD nor the data can be recovered," and SSDs put in service in a batch can likely fail simultaneously.

SK Hynix Samples Terabyte-Level 128-Layer 4D NAND Storage

SK Hynix starts sampling storage solutions based on 128-layer 4D NAND, with "terabyte-level" high-density solutions aimed at all segments of the market, from high-end smartphones to the datacentre.

First revealed back in June 2019, the 128-layer 1Tb TLC NAND promises both ultra-low power and ultra-thin solutions with greater capacities compared to the previous generation. Speed also gets a boost, from the 1.2GT/s of the previous generation 96-layer 3D NAND to 1.4GT/s. To stack 128 layers, SK Hynix uses a multi-stacked design and technologies such as ultra-homogeneous vertical etching and multi-layer thin-film cell formation, all with a low-power circuit design to ensure no increases to power consumption.

The WD Ultrastar DC SS540 SAS SSDs

Western Digital (WD) launches the Ultrastar DC SS540 SAS SSD range aimed at mission critical applications, including OLTP, OLAP, hyperconverged infrastructure (HCI) and software-defined storage (SDS) workloads.

Designed for mixed and write intensive workloads, the SSDs are based on the 6th generation dual-port SAS 12Gbps platform co-developed with Intel, and carry 96-layer 3D TLC NAND memory in the 2.5-inch form factor. As such, the drives are drop-in compatible with existing servers with support for 9, 11 and 14W per drive power options, and support extended error correction code (ECC with a 1x10^-17 bit error rate) to ensure high performance and data integrity, exclusive-OR (XOR) parity in case a whole NAND die fails and parity-checked internal data paths.

The OWC RAID Storage/Thunderbolt 3 Dock Combo

Mac accessory maker OWC announces the Mercury Elite Pro Dock-- a Thunderbolt 3 device offering a range of connectivity together with two bays for 2.5- or 3.5-inch SSDs or HDDs for use in RAID configuration.

Based on the Intel JHL6540 controller, the Mercury Elite Pro Dock can be daisy chained with other Thunderbolt 3 devices. The two drive bays support RAID0, RAID 1, JBOD, and Span modes to maximise reliability (by mirroring), double sequential read/write speeds to 530MB/s in case of 14TB HDDs or the drives either separately or as a single drive. An ASMedia controller enables RAID through a special switch on the back. In total the dock supports up to 28TB of storage capacity.

Western Digital Starts Storage Systems Exit

Western Digital starts to make an exit from Storage Systems as it sells off the IntelliFlash business to artificial intelligence (AI) and multi-cloud management vendor DDN. The financial details of the deal are not available.

The sale follows an expansion of a partnership between the two companies, one seeing DDN increase the purchase of WD HDD and SSD devices. It is also the first step of the WD "strategic intention" to exit Storage Systems, which consists of the IntelliFlash and ActiveScale businesses. The company is currently looking for a willing buyer for ActiveScale, an action allowing to focus its Datacentre Systems portfolio around the core Storage Platforms business, which includes the OpenFlex platform and fabric-attached storage technologies.
