Prism Element
Prism Element Dashboard概要
PE控制台也稱為 Prism Element，可提供圖形使用者界面管理 Nutanix 叢集中的大多數活動。Prism控制台的畫面分為以下幾個板塊：
-
主選單欄 : 主選單欄位於 Prism控制台中每個畫面的頂部。叢集的名稱出現在主選單欄的最左側。在叢集名稱的右側，可以從下拉列表( Home, Health, VM, Storage, Hardware, DR, Analysis, 和 Alerts等等中)中選擇實體，以顯示有關該實體的資訊。還可以從主選單欄右側的下拉列表中搜索特定主題或選擇各種任務。此外，主選單欄還包括各種狀態圖標，用於快速存取運行狀況、警示和事件資訊。
-
實體視圖 : 每一個實體都有一個儀表板視圖。部分實體( VM, Storage, Hardware, and Data Protection )還包括額外的視圖，例如圖表或表格視圖，可以從實體的儀表板中選擇。
-
畫面選單欄 : 部分實體儀表板的主選單下方還包含另一個選單，用於提供特定於該畫面的選項。以下示例來自Storage儀表板，該選單欄上出現有三個視圖分頁(Overview、Diagram和Table)和三個任務按鈕(+ Storage Container、+ Volume Group和+ Storage Pool)。
-
使用狀況和效能/健康統計 : 大部分視圖都包含各種圖表，用於提供有關使用與效能或運行狀況(或二者兼具)的統計資訊。根據查看的實體，其使用狀況和效能/運行狀況統計資訊各有不同。例如，VM的使用統計資訊會按 CPU 和記憶體兩方面內容來顯示，而磁碟使用率統計資訊則以 TB 為單位顯示磁碟容量。在大多數情況下，效能統計資訊表現為 IOPS、延遲和頻寬三個方面。
-
警報和事件訊息 : 一些視圖中會包括列出當前事件和警示訊息的統計。所列出的訊息特定於各自情景，例如，Storage畫面中只會出現與Storage相關的警示和事件。點擊訊息，即可打開該訊息中警示或事件的相應視圖
點擊"叢集名稱"可以修改叢集細節
- 在 Cluster Name 欄位中，輸入（或更新）叢集的名稱。
- 在 FQDN 欄位中，輸入集群的完全限定功能變數名稱 （FQDN）。
- 在 Virtual IP 字段中，輸入將用作叢集虛擬 IP 的 IP 位址。
- 在 ISCSI 資料服務 IP 位址欄位中，輸入（或更新）用於 Nutanix 卷和其他資料服務應用程式的 IP 位址。
- Retain Deleted VMs，勾選啟用回收站保留已刪除的虛擬機 24 小時。
調整Virtual IP或是ISCSI資料服務IP會導致叢集某些服務功能受影響，需警慎評估。
Prism Element 選單
從左側的下拉列表中選擇視圖(實體名稱)會顯示有關該實體的資訊。 從以下選項中選擇：
- Home: 顯示主儀表板。
- Health: 顯示運行狀況儀表板。
- VM: 顯示虛擬機器資訊儀表板。
- Storage: 顯示儲存資訊儀表板。
- Network (僅限 AHV): 顯示網路可視化工具。
- Hardware: 顯示硬體資訊儀表板。
- File Server: 顯示檔案伺服器儀表板。
- Data Protection: 顯示資料保護資訊儀表板。
- Analysis: 顯示用於創建和運行效能監視器的界面。
- Alerts: 顯示警示和事件訊息畫面。
- Tasks: 顯示任務訊息的畫面。
- LCM: 顯示生命週期管理器(LCM)儀表板。
- Settings: 如同點擊主選單右側的齒輪圖標一樣，將顯示設置選單。
Prism Element -> Health
健康監控提供一系列狀態檢查來監控叢集的運作狀況。
NCC
一種檢查數百個項目的整體健康的機制，當叢集中發現問題時，請先執行它來做故障排除。
- 實際是一組腳本
- 檢查結果用於產生警告、輸出健康資訊到文字檔案中、顯示Health(健康)選單等。
- 建議每週運行並透過電子郵件接收報告
由於NCC本身是軟體功能，建議保持升級到最新版本，維持檢查健康機制來確認叢集健康非常重要。
在開Case時除錯和LCM升級前後等維護我們都會執行NCC Health Checks 檢查叢集健康狀態
Health -> Actions -> Run NCC Checks
All Checks -> Run
Tasks -> 找到Health Check的排程 -> Succeeded -> Download Output即可下載檢測的日誌

Prism Element -> Storage
Nutanix 叢集中的儲存空間依層次結構組織為多個元件，可讓您管理容量和效能。
儲存層
每種類型的儲存硬體（SSD-PCIe (NVMe)、SSD (SATA SSD) 和 HDD）都放置在儲存層中。您可以透過 Web 控制台確定儲存池中磁碟的層細分。
儲存池
儲存池是來自一層或多層的實體磁碟組。儲存池提供實體隔離，因為儲存設備一次只能指派給單一儲存池。建立叢集時，預設的預定義儲存池可用。此池包括叢集中所有主機上所有磁碟的總容量。
儲存容器
儲存容器是儲存池中可用儲存的子集。儲存容器是在儲存池中建立的，用於保存虛擬機器使用的虛擬磁碟 (vDisk)。預設情況下，儲存是精簡配置的，這意味著在寫入資料時將實體儲存按需分配給儲存容器，而不是在建立儲存容器時分配預先定義的容量。在容器層級啟用壓縮、重複資料刪除和糾刪碼等儲存效率功能。
卷組
卷組是邏輯上相關的虛擬磁碟（或磁碟區）的集合。磁碟區組直接或使用 iSCSI 連接到 VM。您可以將虛擬磁碟新增至磁碟區群組、將它們附加到一個或多個使用者、將它們包含在災難復原策略中以及執行其他管理任務。您也可以從一個虛擬機器分離磁碟區群組並將其附加到另一虛擬機器（可能位於磁碟區組複製到的遠端位置）。
您可以在儲存容器上建立卷組，並透過以下方式之一啟用對卷組的存取：
- iSCSI :對卷組的 iSCSI 訪問是通過 Nutanix Volumes 提供。
- 如果管理程式是 AHV，則可以創建一個卷組並將其附加到一個或多個 VM 作為 SCSI 磁碟，使用 Prism Element Web 控制台、Nutanix REST API 或 nCLI 或 aCLI 命令。
一些產品、功能或解決方案可能需要通過多個 iSCSI 啟動程式(multiple iSCSI initiators)或多個 VM 連接對卷組進行同時訪問。
- Oracle RAC（裸機和虛擬化環境）
- Linux VMs
- Linux guest VM clustering (also known as RHEL HA)
- Windows Failover Clustering
- Veritas InfoScale Storage
- IBM Spectrum Scale (GPFS)
Lab: iSCSI配置
Step1 配置 Windows 用戶端以實現 ISCSI 連接
使用 Windows 2008 R2 或 Windows 2012 （R2） 更高版本。如果您有 Windows 2003 伺服器下載 Microsoft iSCSI Software Initiator：http://www.microsoft.com/en-us/download/details.aspx?id=18986
Step2 啟動 iSCSI 服務並將啟動類型設置為自動
執行services.msc
找到Microsoft iSCSi Initiator Service -> 內容 -> 啟動類型：自動，服務狀態啟動
點擊右鍵 -> 啟動
啟動完成顯示：執行中
Step3 查找虛擬機內iSCSI啟動器的IQN
執行 iscsicpl.exe
在設定，複製啟動器名稱
Step4 配置卷組
回到Prsim Element -> Storage -> Table -> +Volume Group
給其Name、在Storage給其硬碟、Access Settings勾選Enable External Client Access、在Client加入之前複製的IQN，之後Save
Step5 連接到發現的iSCSI Target並保留連接
回到iSCSI啟動器 -> 探索 -> 搜索目標入口 -> 輸入Nutanix Data Service IP
再到目標，可以觀察到"已經連線"
Step6 硬碟配置
輸入diskmgmt.msc
即可看到未初始化的硬碟，連線初始化與格式化硬碟，即完成配置
Lab: AHV直接附加卷組
Step 1 Prism Element -> Storage -> Table -> + Volume Group -> 給其名稱和儲存
Step2 將VG 附加在虛擬機上
點擊剛剛建立的VG -> Update -> + Attach to a VM
Step3 硬碟配置
輸入diskmgmt.msc
即可看到未配置未初始化的硬碟，請依照之前的步驟配置
Volume Group Lab結論：
透過AHV直接附加卷組到VM的功能簡化了iSCSI的配置。
虛擬磁碟
虛擬磁碟是在儲存容器或磁碟區組中建立的，以便為虛擬機器提供儲存。當虛擬磁碟對應到虛擬機器時，它會顯示為 SCSI 裝置。
