英特尔SSD P4500是否支持VSS(可变扇区大小)功能? 如果没有,为什么? 我知道SSD P3500 / P3600 / P3700系列支持VSS功能。 以上来自于谷歌翻译 以下为原文 Have a good day! Does Intel SSD P4500 support VSS(Variable Sector Size) functions? If not,Why? I known that SSD P3500/P3600/P3700 series are support VSS functions. |

嗨hmily_jian,
感谢您在英特尔社区发帖。 根据本指南,NVMe *驱动器使用可变扇区大小(VSS)技术。 由于英特尔®SSDDC P4500系列是NVMe *驱动器,它应支持VSS:在NVM Express *驱动器上更改可变扇区大小 本指南介绍如何使用英特尔®SSD数据中心工具(DCT)更改可变扇区大小,您可以尝试使用驱动器来确认它是否受支持。 我希望这些信息能回答你的问题。 祝你今天愉快。 此致,Diego V. 以上来自于谷歌翻译 以下为原文 Hi hmily_jian, Thank you for posting in the Intel communities. According to this guide, the NVMe* drives use Variable Sector Size (VSS) technology. As the Intel® SSD DC P4500 Series is an NVMe* drive, it should support VSS: Change Variable Sector Size on NVM Express* Drives This guide explains how to change the Variable Sector Size using the Intel® SSD Data Center Tool (DCT), you can try it with your drive to confirm if it is supported. I hope this information answers your question. Have a nice day. Regards, Diego V. |

谢谢您的回复。 我使用isdct工具更改Intel Optane SSD DC P4800X上的SectorSize。 (我暂时没有找到P4500的磁盘。) 我发现扇区大小可以在512到4096之间切换。当我尝试将SectorSize更改为4160时。报告了一个错误。 所以我的问题是:英特尔SSD DC P4500 / P4510与英特尔Optane SSD DC P4800X相同,是否支持VSS功能,但它也不能 改为4160? 谢谢。 $ sudo isdct start -intelssd 0 -NVMeFormat LBAformat = 5 SecureEraseSetting = 0 ProtectionInformation = 0 MetaDataSettings = 0 警告! 您已选择格式化驱动器! 继续格式化? (Y | N):Y 格式化...(这可能需要几分钟才能完成) - 英特尔Optane(TM)SSD DC P4800X系列PHKE736100RS375AGN - 状态:NVMe命令报告了一个问题。 并将SectorSize更改为4096.它成功了。 $ sudo isdct start -intelssd 0 -NVMeFormat LBAformat = 3 SecureEraseSetting = 0 ProtectionInformation = 0 MetaDataSettings = 0 警告! 您已选择格式化驱动器! 继续格式化? (Y | N):Y 格式化...(这可能需要几分钟才能完成) - 英特尔Optane(TM)SSD DC P4800X系列PHKE736100RS375AGN - 状态:NVMeFormat成功。 以上来自于谷歌翻译 以下为原文 Thank you for your reply. I use isdct tool to change the SectorSize on Intel Optane SSD DC P4800X. (I haven't found the disk of P4500 for the time being.) And I found Sector size can be switched between 512 and 4096. when I try to change the SectorSize to 4160. A mistake was reported. So My question is : Does the Intel SSD DC P4500/P4510 the same with Intel Optane SSD DC P4800X support VSS function, but It also can't change to 4160? Thank you. $sudo isdct start -intelssd 0 -NVMeFormat LBAformat=5 SecureEraseSetting=0 ProtectionInformation=0 MetaDataSettings=0 WARNING! You have selected to format the drive! Proceed with the format? (Y|N): Y Formatting...(This can take several minutes to complete) - Intel Optane(TM) SSD DC P4800X Series PHKE736100RS375AGN - Status : NVMe command reported a problem. And change the SectorSize to 4096 .It was succeed. $sudo isdct start -intelssd 0 -NVMeFormat LBAformat=3 SecureEraseSetting=0 ProtectionInformation=0 MetaDataSettings=0 WARNING! You have selected to format the drive! Proceed with the format? (Y|N): Y Formatting...(This can take several minutes to complete) - Intel Optane(TM) SSD DC P4800X Series PHKE736100RS375AGN - Status : NVMeFormat successful. |

intel_corp 我在英特尔SSD P4510上使用isdct工具更改扇区大小为4160。 据报道有一个错误。 $ sudo isdct start -intelssd 2 -NVMeFormat LBAformat = 5 SecureEraseSetting = 0 ProtectionInformation = 0 MetaDataSettings = 0 警告! 您已选择格式化驱动器! 继续格式化? (Y | N):Y 格式化...(这可能需要几分钟才能完成) - 英特尔SSD DC P4510系列BTLJ724400FU1P0FGN - 状态:LBA格式无效 以上来自于谷歌翻译 以下为原文 intel_corp And I use isdct tool change sector size to 4160 on Intel SSD P4510.

嗨hmily_jian,根据英特尔®SSDDCT用户指南(https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/Intel_SSD_DCT_3_0_x_User_Guide.pdf),LBA格式参数可以 是一个从0到驱动器具有的最大LBA格式数的数字,它被称为NumLBAFormats。 您可以使用show命令检查此参数,如下所示:isdct show -all -intelssd您应运行该命令以检查每个驱动器的可能格式数。 如果NumLBAFormats值为2,那么您只能使用0,1或2作为LBAformat参数.Regards,Diego V. 以上来自于谷歌翻译 以下为原文 Hi hmily_jian, According to the Intel® SSD DCT User Guide (https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/Intel_SSD_DCT_3_0_x_User_Guide.pdf), the LBAformat parameter could be a number from 0 to the maximum number of LBA formats the drive has, which is referenced as NumLBAFormats. You can check this parameter with the show command as follow: isdct show -all -intelssd You should run that command to check the number of possible formats for each drive. If the NumLBAFormats value is 2, then you can only use 0, 1 or 2 for the LBAformat parameter. Regards, Diego V. |

andyouwo 发表于 2018-11-6 08:36 intel_corp 祝你今天愉快。 谢谢您的回复。 我发现英特尔SSD DC P4510的NumLBAFormats = 1.仅支持512和4096扇区大小。 所以我的问题是:为什么P4510不能支持4160个扇区? 谢谢。 以上来自于谷歌翻译 以下为原文 intel_corp Have a nice day. Thank you for your reply. I found Intel SSD DC P4510 's NumLBAFormats = 1. only support 512 and 4096 sector size. So my question is: Why P4510 can not support 4160 sectors? Thank you. |
