It is also not clear if other models of the ConnectX SmartNIC family (4, 6 and 7) will also show this same problem when using speeds of 50GB or more. DataCore are recommending reducing the speed of the NIC to 25GB as this has been shown to resolve the problems stated above. We are currently investigating this problem. Storage Hardware – Lenovo Intel S4510 and S4610 SATA SSD (only 1.8 TB and 3.84 TB are affected) Affects the DataCore Server After 1700 hours of cumulative power-on idle time users can see critical errors under certain use conditions. The drive may report BAD_CONTEXT_2033, BAD_CONTEXT_1042 or excessive LBA mismatch (SMART attribute B8h) after. Once the error code is triggered, the drive will fail to respond on the bus.

DataCore Software always recommend that users contact the third-party vendor directly to see if there are any updates or fixes since they were documented here. DataCore always recommend that the latest software drivers, firmware and/or BIOS are used on any SAN component (unless of course they are listed here as not working as expected). A few of the issues documented here were discovered during DataCore’s own testing but most have been reported by end users and then subsequently confirmed by the third-party Vendor. Known issues that apply to DataCore's own products are in their own release notes which are all available from the DataCore Support website.

A crash in Microsoft’s mpio.sys driver may occur when two or more paths to an MPIO disk device are removed, unexpectedly at the same time. This may affect: • Hosts that being served Virtual Disks that are being managed either by Microsoft’s own MPIO or DataCore’s Windows Integration Kit both of which use the Widows mpio.sys driver. • DataCore Servers that are using iSCSI Mirrored Virtual Disks – where SANsymphony utilizes the mpio.sys driver. Fibre Channel mirrored Virtual Disks are unaffected. This issue was fixed in an update issued in January 12th, 2021. Also see January 12, 2021—KB4598243 (OS Build 14393.4169) https://support.microsoft.com/en-us/help/4598243 Windows 2016/2012/2012 R2/2008 Affects clustered, hyper-converged DataCore Servers Do not use the DataCore Loopback port to serve mirrored Virtual Disks to Hyper-V Virtual Machines This known issue only applies when SANsymphony is installed in the root partitions of clustered, Hyper-V Windows servers where virtual disks are ‘looped-back’ to the Windows Operating system for use by Hyper-V Virtual Machines. Also see: https://docs.datacore.com/SSV-WebHelp/hyperconverged_virtual_san_software.htm A limitation exists in the DataCore SCSI Port driver - used by the DataCore Loopback Ports - whereby if the DataCore Server providing the ‘Active’ cluster path is stopped, the remaining DataCore Server providing the ‘Standby’ path for the Hyper-V VMs is unable to take the SCSI Reservation (previously held by the stopped DataCore Server). This will result in a SCSI Reservation Conflict and prevent any Hyper-V VM from being able to access the DataCore Disks presented by the remaining DataCore Server. In this case please use iSCSI connections as ‘Loopbacks’ for SANsymphony DataCore Disks presented to Hyper-V Virtual Machines. Affects the DataCore Server BitLocker Drive Encryption This server feature must not be installed on a DataCore Server as it will prevent SANsymphony’s Disk Pool feature from working.

  • Western Digital Acquires Virident
    Western Digital Acquires Virident Whopping $685 Million Purchase Price Disk drive maker Western Digital Corp announced on 9 September 2013 that it is buying Virident Systems, Inc. which will be merged into HGST, a wholly- owned subsidiary of Western Digital.. Virident will be acquired for approximately $685 million in cash, consisting of about $645 million in enterprise value, net of Virident’s estimated cash balance. Virident believes its integration with HGST will strengthen its marketing by leveraging HGST’s strong brand, extensive channel relationships, and global customer reach. Who is Virident? Virident is a small independent manufacturer of very high end PCIe SSDs. The company has, from the beginning, had a relentless focus on consistency of performance, which is one aspect of SSDs that has received very little attention until recently. Virident started out as a manufacturer of two high-performance dedicated appliances, one for running MySQL database software, and the other to support the open-source memcached storage network caching software. Virident and competitor Schooner both entered this market at the same time. Both found that data centers were moving away from dedicated hardware and toward virtualization, forcing both companies to revise their plans. Schooner focused on software optimization and was recently acquired by SanDisk. Virident migrated to NAND flash-based PCIe SSDs similar to, but faster than, those pioneered by Fusion-io. It was able to do this because its original appliances were based on NOR flash, a very badly-behaved technology when it comes to write cycles. Virident applied its superior understanding of flash write cycle management to NAND and achieved superior results.

  • Virtual Desktop Scalability and Performance with Vmware View 5.2 and Virident Flashmax Ii Storage
    VIRTUAL DESKTOP SCALABILITY AND PERFORMANCE WITH VMWARE VIEW 5.2 AND VIRIDENT FLASHMAX II STORAGE Whether you are planning to make the move to desktop virtualization or are looking to expand your existing virtual desktop infrastructure (VDI), it is important that you choose the right software and storage for your enterprise environment. It is also vital to be able to add hardware and predictably scale your environment so that you know how many users you can expect to support as your VDI needs grow. Choosing VMware View 5.2 software with a fast and reliable internal storage solution, such as Virident FlashMAX II™ storage devices, can maximize performance, reduce latency, and scale predictably as you add users. In the Principled Technologies labs, we found that a single server running VMware View 5.2 virtual desktops with two low-profile Virident FlashMAX II storage devices could support 162 virtual desktops with nearly no latency to provide an excellent experience for end users. To verify how predictably and linearly this solution scales, we had only to add another server; two servers, each with two Virident devices, scaled perfectly to support 324 users. We also ran a storage-intensive recompose job on the desktops and found that Virident FlashMAX II devices could handle heavy maintenance jobs without sacrificing end-user performance. JANUARY 2013 A PRINCIPLED TECHNOLOGIES TEST REPORT Commissioned by VMware, Inc. and Virident Systems, Inc. MANY USERS, VERY LOW LATENCY, AND PREDICTABLE SCALABILITY The success of a virtual desktop environment is dependent on the number of enterprise users your solution supports, the performance and response times it provides for your users, and the ability to predict the number of users you can expect to support when you scale your hardware.

  • Micron: NAND Flash Architecture and Specification Trends
    NAND Flash Architecture and Specification Trends Michael Abraham ([email protected]) Applications Engineering Manager Micron Technology, Inc. Santa Clara, CA USA August 2009 1 Abstract As NAND Flash continues to shrink, page sizes, block sizes, and ECC requirements are increasing while data retention, endurance, and performance are decreasing. These changes impact systems including random write performance and more. Learn how to prepare for these changes and counteract some of them through improved block management techniques and system design. This presentation also discusses some of the tradeoff myths – for example, the myth that you can directly trade ECC for endurance Santa Clara, CA USA August 2009 2 NAND Flash: Shrinking Faster Than Moore’s Law 200 100 Logic 80 DRAM on (nm) ii 60 NAND Resolut 40 Micron 32Gb NAND (34nm) 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 Semiconductor International, 1/1/2007 Santa Clara, CA USA August 2009 3 Memory Organization Trends Over time, NAND block size is increasing. • Larger page sizes increase sequential throughput. • More pages per block reduce die size. 4,194,304 1,048,576 262,144 65,536 16,384 4,096 1, 024 256 64 16 Block size (B) Data Bytes per Page Pages per Block Santa Clara, CA USA August 2009 4 Consumer-grade NAND Flash: Endurance and ECC Trends Process shrinks lead to less electrons ppgger floating gate.
