VCF/VVF/vSAN 訂閱授權計算器(License Calculator via BASH)

[toc] VMware 更新產品策略，提供全新簡化的產品組合。並由原先 CPU（Socket）數量計價調整為**核心（Cores）數量計價**。另外根據產品組合提供進階附加服務（Add-on Services）加購，相關產品資訊請參考官方網站。 ![圖片](https://hackmd.io/_uploads/ByBidG_ha.png) # 參考資訊由於計價方式調整，所以官方也提供相關計價說明及工具，以便提供客戶對於目前及未來佈署環境所需授權數量的評估規劃。目前計價重點則在於 **VCF, VVF 的核心數授權計算**和 **vSAN Add-on 容量授權計算**。 ## 官方知識庫目前有關授權計算，官方提供以下相關說明： - [Counting Cores for VMware Cloud Foundation and vSphere Foundation and TiBs for vSAN (95927)](https://kb.vmware.com/s/article/95927) - [License Calculator for VMware Cloud Foundation, VMware vSphere Foundation and VMware vSAN. (96426)](https://kb.vmware.com/s/article/96426) :::info - [**VMware KB 95927**](https://kb.vmware.com/s/article/95927) 提供的 PowerCLI 腳本 **`FoundationCoreAndTiBUsage`** 可協助客戶清點現有 vSphere 環境，以便評估計算運算(compute)訂閱數量或 vSAN 所需的 VCF/VVF 訂閱容量。 - [**VMware KB 96426**](https://kb.vmware.com/s/article/96426) 提供的 PowerShell 腳本 **`vcf-vvf-calculator.ps1`**，讓無法執行前個 PowerCLI 腳本的客戶，可以搭配手動輸入的 CSV 檔案 `sample-list.csv` 所提供的參數，執行模擬來計算運算(compute)訂閱數量或 vSAN 所需的 VCF/VVF 訂閱容量。 - 請參考原廠 KB 說明及指示，完成相關評估計算功能。 - 目前**已取消最低購置 vSAN 訂閱容量條件**。其他相關採購限制或條件皆以官方公開說明為主。 ::: # 自製工具因為沒有 PowerShell 和 PowerCLI 這麼高檔的工具，還好終端機有提供 **BASH** 環境，就簡單地仿造 William 大神撰寫簡易工具吧！有關[[知識庫#959275]](https://kb.vmware.com/s/article/95927) 中，表格內提及的說明範例，以及腳本程式說明，可以參考[[這裡]](#使用-BASH-和-GOVC-撰寫程式估算-VMware-vSphere-訂閱授權)。 ## 腳本參考官方腳本工具提供者為 [**William 大神**](https://williamlam.com/about)，以下是作者的部落格連結。 - [Updated Inventory & Calculator Scripts for counting Cores/TiBs for VMware Cloud Foundation (VCF) and VMware vSphere Foundation (VVF)](https://williamlam.com/2024/02/updated-inventory-calculator-scripts-for-counting-cores-tibs-for-vmware-cloud-foundation-vcf-and-vmware-vsphere-foundation-vvf.html) ## 執行結果先觀摩 William 大神的程式輸出結果。 ![image](https://hackmd.io/_uploads/HknnhqH2a.png) 接著看一下仿造結果吧！ ![image](https://hackmd.io/_uploads/BkQ46cr2T.png) ![image](https://hackmd.io/_uploads/BJVc6cH2a.png) ![image](https://hackmd.io/_uploads/Bku3a9r2a.png) 還行！目前只有基本除錯，而且提供快速自用，**實際使用還請以原廠提供工具輸出結果為主**。 :::info - **Required VCF/VVF Compute Licenses Per Cluster** 該叢集所需 VCF/VVF 運算授權許可 - | 名稱 | 說明 | | --- | --- | | CLUSTER | 叢集名稱 | | NUM_HOSTS | 叢集中 ESXi 主機總數 | | NUM_CPU_SOCKETS_PER_HOST | 每部 ESXi 主機的 CPU(socket) 數量 | | NUM_CPU_CORES_PER_SOCKET | 每部 ESXi 主機 CPU 的核心(core) 數量 | | FOUNDATION_LICENSE_CORE_COUNT | 該叢集所需 VCF/VVF 核心授權數量 | - **Required vSAN Licenses Per Cluster** 該叢集所需 vSAN 存儲授權許可 | <div style="width: 150pt">名稱</div> | <div style="width: 440pt">說明</div> | | --- | --- | | CLUSTER | 叢集名稱 | | NUM_HOSTS | 叢集中 ESXi 主機總數 | | NUM_CPU_SOCKETS | 叢集中 CPU(sockets) 總數 | | NUM_CPU_CORES | 叢集中核心(cores) 總數 | | FOUNDATION_LICENSE_CORE_COUNT | 叢集中 VCF/VVF 產品的核心授權許可總數 | | ENTITLED_VSAN_LICENSE_TIB_COUNT | 叢集中 VCF/VVF 產品取得的 vSAN TiB 授權容量 | | REQUIRED_VSAN_TIB_CAPACITY | 叢集所需求的 vSAN (RAW) TiB 總容量| | VSAN_LICENSE_TIB_COUNT | <font size="1">從需求總容量和取得的 vSAN 授權容量比較後，該叢集所需的 TiB 授權容量。<br>- 若**該數字為 0 或負數**，表示**不需要額外的授權**，且該數字表示超過多餘的授權容量。<br>- 若**該數字為正數**，表示**還需要此數字的額外授權容量**，才能滿足需求。</font> | ::: ## 程式源碼 ### sample_input 手動輸入不同配置的資料，以便提供腳本檔產生出對應的 VCF/VVF 和 vSAN 所需的訂閱授權數量。 :::warning - <font color=red>**請勿變更第一行內容**</font>。 > 雖然偷懶我也沒用到！ - 每一行代表一個 vSphere 或 vSAN 叢集資料。 - 每列的說明請參考 [**VMware KB 96426**](https://kb.vmware.com/s/article/96426)，其中有完整詳細的內容說明。 - vSAN 容量單位為 TiB。 - 1 TB ~= 0.909 TiB - 1 TiB ~= 1.100 TB ::: ```= CLUSTER_NAME,NUMBER_OF_HOSTS,NUMBER_OF_CPU_SOCKETS,NUMBER_OF_CPU_CORES_PER_SOCKET,VSAN_ENABLED_CLUSTER,TOTAL_RAW_VSAN_TIB CL1,4,2,18,Yes,13.9 CL2,4,2,20,Yes,11.5 CL3,3,2,16,Yes,9.6 CL4,8,2,24,Yes,460.9 CL5,7,2,24,Yes,403.3 CL6,9,2,10,Yes,230.4 CL7,10,2,20,Yes,614.5 CL8,4,2,32,Yes,230.4 ``` :::info 每列內容請按照下列內容依序填入，並以 **`','`** 區隔不用帶空白(會出事！) - 叢集名稱 - ESXi 主機數量 - 每台 ESXi 主機的 CPU(Socket) 數量 - 每個 CPU(Socket) 的核心 (Core) 數量 - 該叢集是否啟用 vSAN > 這個參數條件沒另外寫函式判斷，就都當作是 vSAN 叢集 - 實際 vSAN RAW 容量 (TiB) ::: ### vcf_vvf_license_calculator.sh 程式撰寫，單純仿造官方程式輸出結果，至於授權數量計算就是由目前取得資訊和個人研讀認知，直接改成 BASH 腳本語法完成。 :::info - **執行方式** ./vcf_vvf_license_calculator.sh -i [input_file] -d [vcf|vvf] - 以下程式碼範例僅供參考，**實際使用還請以原廠提供工具輸出結果為主**。 - 若有發現邏輯錯誤，還請指正，感恩。 ::: ```bash= #!/bin/bash # # edited by semigod # # - Counting Cores for vSphere Foundation and VMware Cloud Foundation and TiBs for vSAN Add-on (95927) # > https://kb.vmware.com/s/article/95927 # - License Calculator for VMware Cloud Foundation, VMware vSphere Foundation and VMware vSAN.
