PCIE的简单配置(r8笔记第82天)

最近测试了一下PCIE-SSD在数据库环境的迁移 和加压情况，IOPS无可置疑，比起机械硬盘确实是高了很多个量级，在数据环境中的IO方面确实有很稳定的提升，目前使用闪存产品系列，看官网最新的发布 已经支持6T了，这个着实让我想起曾经的U盘，几十M,几百兆都曾经风光一时。 基本的软件要求如下，摘自用户文档中，各个厂商应该都差不多。

尽管官网的发布是支持Linux 5,6其实安装包里已经有了7的支持版本了，这个绑定是内核粒度，确实非常细。

1.1在官网下载rpm包，解压

如果是Linux 6版本，基本就是参考CentOS，可以看到版本6有以下内核版本的rpm ./CentOS/6: total 5816 -rw-rw-r-- 1 1000 1000 559112 Mar 31 08:18 shannon-module-2.6.32-131.0.15.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 563396 Mar 31 08:18 shannon-module-2.6.32-220.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 563028 Mar 31 08:18 shannon-module-2.6.32-279.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 528616 Mar 31 08:18 shannon-module-2.6.32-358.23.2.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 528456 Mar 31 08:18 shannon-module-2.6.32-358.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 528204 Mar 31 08:18 shannon-module-2.6.32-431.11.2.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 527836 Mar 31 08:18 shannon-module-2.6.32-431.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 527528 Mar 31 08:18 shannon-module-2.6.32-504.12.2.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 527732 Mar 31 08:18 shannon-module-2.6.32-504.8.1.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 527756 Mar 31 08:18 shannon-module-2.6.32-504.el6.x86_64-2.8-6.1.x86_64.rpm -rw-rw-r-- 1 1000 1000 555616 Mar 31 08:18 shannon-module-2.6.32-71.el6.x86_64-2.8-6.1.x86_64.rpm 1.2选择适合的内核版本，安装rpm [root@db117 6]# rpm -ivh shannon-module-2.6.32-431.el6.x86_64-2.8-6.1.x86_64.rpm Preparing... ########################################### [100%] 1:shannon-module-2.6.32-4########################################### [100%] 1.3验证是否安装完成 [root@db117 rpm]# ll /lib/modules/2.6.32-431.el6.x86_64/extra total 2448 -rw-r--r-- 1 root root 2502739 Mar 13 17:28 shannon.ko 安装shannon-utils [root@db117 rpm]# rpm -ivh shannon-utils-2.8-6.1.x86_64.rpm Preparing... ########################################### [100%] 1:shannon-utils ########################################### [100%] 1.4检查安装情况： [root@db117 rpm]#fdisk -l Disk /dev/dfa: 800.0 GB, 800000573440 bytes 32 heads, 32 sectors/track, 1525880 cylinders Units = cylinders of 1024 * 512 = 524288 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 32768 bytes Disk identifier: 0x00000000 [root@db117 rpm]# ls /dev/df* /dev/dfa [root@db117 rpm]# rpm -qa | grep shannon shannon-utils-2.8-6.1.x86_64 shannon-module-2.6.32-431.el6.x86_64-2.8-6.1.x86_64 1.5查看PCIE-SSD状态 [root@db117 rpm]# shannon-status /dev/scta Basic Information: Control Device Node: /dev/scta Driver Mode: Block Block Device Node: /dev/dfa Device State: Attached Access Mode: ReadWrite Product Model: Direct-IO G3i Serial Number: SH15608K734181 UDID: 1CBO0275-1CB00030-04815608-4B734181 PCI VendorID: 1CB0 PCI DeviceID: 0275 PCI Bus Address: 05:00:0 PCI Link Speed: pcie 2.0 x 8 Firmware Version: 3.2 Firmware Build: f2796a40 Driver Version: 2.8.6.1 FPGA Reconfig Support: Yes Logical Sector: 512 Physical Sector: 4096 Disk Capacity: 800.00 GB Physical Capacity: 1094.72 GB Overprovision: 26.93% Atomic Write: Disabled Prioritize Write: Disabled Work Status: Controller Temperature: 45 degC, Max 45 degC Board Temperature: 30 degC, Max 31 degC Flash Temperature: 32 degC, Max 32 degC Internal Voltage: 1022 mV, Max 1028 mV Auxiliary Voltage: 1833 mV, Max 1842 mV Power Cycles: 8 Power On Time: 46 hours 12 minutes Dynamic Bad Blocks: 0 Media Status: Healthy SEU Flag: Normal Lifetime Data Volumes: Host Write Data: 73555.63 GB Host Read Data: 72660.33 GB Total Write Data: 80719.31 GB Lifetime Write Amplifier: 1.090 Estimated Life Left: 98.560% Realtime IO Statistics: Write Bandwith: 0.000 MB/s Write IOPS: 0.000 K Avg Write Latency: 0.000 ms Total Write Bandwith: 0.000 MB/s Read Bandwith: 0.001 MB/s Read IOPS: 0.000 K Avg Read Latency: 0.042 ms Write Amplifier: 1.000 Buffer Write Percentage: 0% [root@db117 rpm]# 1.6监控性能 [root@db117 rpm]# shannon-status -m /dev/scta Direct-IO PCIe Flash Card Monitor Program Commands: q|Q exit; g|G general info; m|M main window Monitoring device '/dev/scta' at PCI:05:00:0 Device State: Attached Access Mode: ReadWrite Power Cycles: 8 Power On Time: 46 hours 12 minutes Controller Temperature: 45 degC, Max 45 degC Board Temperature: 30 degC, Max 31 degC Flash Temperature: 31 degC, Max 32 degC Internal Voltage: 1019 mV, Max 1028 mV Auxiliary Voltage: 1833 mV, Max 1842 mV Free Block Count: 2102 Host Write Data: 73555.63 GB Write Bandwith: 0.000 MB/s Write IOPS: 0.000 K Avg Write Latency: 0.000 ms Host Read Data: 72660.33 GB Read Bandwith: 0.000 MB/s Read IOPS: 0.000 K Avg Read Latency: 0.000 ms Total Write Data: 80719.31 GB Total Write Bandwith: 0.000 MB/s Write Amplifier: 1.000, lifetime 1.090 Buffer Write Percentage: 0% 1.7分区格式化： [root@db117 rpm]# fdisk /dev/dfa Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-1525880, default 1): Using default value 1 Last cylinder, +cylinders or +size{K,M,G} (1-1525880, default 1525880): Using default value 1525880 Command (m for help): w The partition table has been altered!
