  POP3 前後端效能影響說明如下 網路使用量 磁碟使用量 處理器 記憶體 POP3 前端伺服器 記憶體 POP3 前端伺服器幾乎不需要記憶體即可有效的操作。POP3 前端伺服器上同時 POP3 工作階段數目增加時，記憶體使用量不會有顯著增加。因為 POP3 用戶端不會持續長時間連線到前端伺服器 (這會讓記憶體使用量相對較小)，所以記憶體不會顯著增加。可以在 POP3 前端伺服器上停用 MSExchangeIS (Store.exe) 服務，進而節省額外的記憶體。如果停用此服務，則 POP3 前端伺服器可以 256 MB 的 RAM 有效執行。 磁碟使用量 當判定專用 POP3 前端伺服器的硬體需求時，請考量您需要的磁碟空間。POP3 前端伺服器極少使用硬碟，因為它充當 Proxy 伺服器，將每個通訊協定工作階段傳遞給適當的後端伺服器。如果為 POP3 虛擬伺服器在 Exchange 系統管理員中啟用通訊協定記錄，則會在前端伺服器上使用硬碟來儲存所需的通訊協定記錄。Windows Server 2003 中的快取管理員也使用磁碟，來將資訊分頁到分頁檔案上，以及自分頁檔案中分頁資訊。作用中系統處理程序需要額外記憶體時，快取管理員使用分頁檔案以暫時從最近未存取的 RAM 儲存資訊。您可以增加伺服器上的 RAM，來讓分頁活動降至最小。 有 256 MB 或更多實際記憶體的 POP3 前端伺服器極少分頁。一個磁碟轉軸用於 POP3 伺服器對於大部份應用程式而言已足夠。如果您執行啟用了通訊協定記錄的大型伺服器，請考量新增第二個轉軸。 網路使用量 在 POP3 前端伺服器上，當您嘗試判定所需的硬體類型時，必須考量網路流量。因為 POP3 前端伺服器可以為多個後端伺服器提供服務，所以發生在前端伺服器上的網路流量經常相當高。任何高階前端伺服器的最小網路需求，是以全雙工模式 (表示資料可以同時傳輸及接收) 執行的單一 100-Mbp 網路介面卡。使用 1:4 的前端伺服器與後端伺服器比例，雙處理器 2.6-GHz 前端伺服器可以將大約 13 Mbps 的資料傳輸給後端伺服器，但是需要一個 GB 網路卡或多個 100 Mbps 網路卡。因為 100-Mbp 全雙工網路連線的飽和點一般認定是大約 7 到 8 Mbps，所以此範...

    Auto Complete Mailbox Moves MoveMailbox.ps1 provides a synchronous mailbox move management experience similar to the Move-Mailbox cmdlet provided in Exchange 2007. By default, scripts are installed at C:\Program Files\Microsoft\Exchange Server\V14\Scripts. For more information, see Move Mailboxes by Using the MoveMailbox.ps1 Script in the Shell . Archive Mailboxes If archive exists, then the archive gets moved with the primary mailbox because the archive and the primary mailbox must reside on the same mailbox database. You will need to factor in the size of the archive before moving the mailbox, not only for database size, but for how long the move will take to complete. If you are moving from an Exchange 2010 server to Exchange 2003 or Exchange 2007 server, you will need to disable the archive before you can move the mailbox. For more information, see Disable a Personal Archive for a Mailbox . Shared Mailboxes and Resource Mailboxes In addition to the de...

1. New-MoveRequest 會存在AD & target DB’s system mailbox 2. Offline Move 是讓user 無法存取, Online Move 則於搬完後才lock source mailbox 3. MRS Instance check 每個DB’s system mailbox 是否有move request 4. MRS 應該 只負責所屬AD site 的move request 5. New-MoveRequest -Identity Ayla@contoso.com -TargetDatabase "DB02" The cmdlet updates active directory and then places a special message to the system mailbox within that Active directory site that a move request has been initiated and the move is set to a status of Queued . Information about the move request is stored in two places: the target database's system mailbox and in Active Directory . If the move is an offline move, the mailbox is locked and can't be accessed until the move is in Completed status. For more information about scenarios in which offline moves are created, see Moving Mailboxes Between Exchange 2010 and Previous Versions of Exchange section previously in this topic. All instances of MRS periodically check the system mailbo...

  1. 信箱搬移由Exchange 2007 CMDlet 改為Exchange 2010 MRS Service 2. MRS 可控制各AD site 的move request, 避免重複的move request 3. MSExchangeMailboxReplication.exe.config . 負責控制move request 設定 4. 可調整一次的信箱搬移數量, 預設為5, Exchange 2003 為4 5.  by default, MRSProxy is disabled 6. MRSProxy 負責remote forest 的跨樹系信箱遷移工作 Mailbox Replication Service When you use the Move Request cmdlets to perform the mailbox move the move will be conducted by MRS. As stated previously, MRS resides on an Exchange 2010 Client Access server and is the service that moves mailboxes from the source database to the target database . In Exchange 2007, the mailbox move was performed by the actual Move-Mailbox cmdlet. Using a service as the agent of the move allows you to move mailboxes asynchronously while they remain accessible to the user. During the move, you maintain the ability to view, cancel, and manage the move request from any Exchange 2010 server in your organization. You can start and stop the...
