1 Le novità di Windows Server 2008 per la gestione degli uffici remoti
Fabrizio Grossi

2 Agenda Read-Only Domain Controller RODC Active Directory
Protezione Dati Novità nel networking Server Core

3 Read-only Domain Controller (RODC)
Riduce la superficie d’attacco dei DC situati in una locazione fisica non sicura (Branch Office) Minore impatto su AD in caso di furto di un DC Per defult in RODC non vengono salvati username/pswrd Viene ridotta la superficie di attacco di AD per un DC compromesso Read-only state Replica unidirezionale per AD e FRS/DFSR Ogni RODC ha il suo account KrbTGT Permission per scrivere in AD molto limitate RODC sono account workstation Facilita la gestione configurazione dei DC nei Branch Office

4 Password Replication Policy
No Account Cached (Default) Pro: Massima sicurezza, comunque fornisce Autenticazione veloce e processa le policy Contro: Nessun accesso Offline. Richiede connettività WAN per il logon Most Account Cached Pro: Facilità la gestione delle Password (diminuisce la sicurezza) Contro: Più Password esposte al RODC Few accounts (branch-specific accounts) cached Pro: Permette l’accesso offline per gli utenti che ne hanno bisogno, e massimizza la sicurezza per gli altri Contro: maggiore amministrazione

5 Active Directory Role Separation
Troppi Domain Administrators La maggior parte sono dei server administrators Role Separation Fornisce un nuovo livello di accesso ai RODC: “local administrator” Include i gruppi Built-in (Backup Operators, ecc.) Impedisce la modifica accidentale dell’AD dagli amministratori del server NON previene un “local administrator” dal modificare il DB locale

6 Active Directory Re-start
Stop/Start dei Directory Services (DS) senza Reboot Riduce il DS downtime per operazioni offline Mantiene gli altri servizi running mentre i DS sono Offline Mentre i DS sono stoppati Funziona come un member server nel dominio Può contattare un altro DC per il domain logon Se non c’è un altro DC attivo, si può fare logon con la password di restore mode (invariato) Si possono fare logon con: Cached credential, Smart Card, biometric

7 Data Protection: Server Backup
Server Backup è un’applicazione per il backup/recovery integrata in Windows Server 2008 che permette di proteggere in modo semplice i server Windows Server 2008 e i dati Protegge file, cartelle, volumi, dati applicativi e componenti del SO Supporta una granularità di recovery che va da tutto il sistema a singoli file o cartelle Richiede una configurazione minima e supporta Wizard che semplificano backup/recovery Utilizza una tecnologia VSS a livello di blocchi e basata su immagini Ottimizzato per i dischi (locali, SAN, iSCSI), ma supporta anche media ottici (DVD) e file server Non supporta tape ...

8 Data Protection: Server Backup
Prima fa un backup completo In seguito esegue automaticamente dei backup incrementali, salvando solo i dati che sono cambiati dall’ultimo backup. Non è necessario, come nelle versioni precedenti, preoccuparsi di impostare manualmente i backup full o incrementali.

9 Data Protection: Server Restore
Restore semplificato: Prima - Per un backup incrementale dovevo fare Restore manualmente da backup multipli Adesso - E’ sufficiente scegliere l’oggetto di cui si vuole fare un Restore e la data. Il Backup lavora con i nuovi tool di Windows Recovery Recovery del SO semplificato. Recovery del Server Disaster Recovery: Recovery su un nuovo hardware.

10 Data Protection: Server Backup vs. NT Backup
Miglioramenti introdotti da Server Backup Grande facilità d’uso (Wizard) Gestione efficiente del Backup (mmc) Remote Administration (supporta script) Aumenta la disponibilità (VSS, nessun Downtime) Aumenta l’affidabilità Protegge i dati delle applicazioni (VSS, provider) Aumenta la granularità (dall’intero server al file) Supporta i dischi (interni, DAS, FC, iSCSI) Supporta media ottici (DVD) Supporta i File Server (target) Semplifica il recovery dei dati (Browse) Total System Recovery (One Reboot)

11 Data Protection: BitLocker Drive Encryption
E’ sempre più spesso necessario proteggere certe tipologie di informazioni Problemi derivanti dalla perdita di computer contententi informazioni sensibili BitLocker è una soluzione di Volume Encryption integrata in Windows Server 2008 Protegge dalla perdita di un computer o di un disco contentente dati sensibili Combinato con il TPM (o con Flash Drive USB se il BIOS lo supporta), offre un adeguato livello di sicurezza fisica Aiuta a ridurre la superficie di attacco Funziona per tutti i volumi

16 Autotuning Receive Window
Scenario: Performance di Rete limitate in scenari WAN o FTTH La TCP receive window di default limita il throughput a 5Mbps su una connessione con latenza di 100ms (coast to coast) Il throughput è anche minore su connessioni intercontinentali o satellitari con latenza più alta Soluzione: Windows Vista/Window Longhorn Server modificano continuamente la TCP Receive Window per ogni connessione Si verificano banda e latenza e si modifica la TCP receive windows di conseguenza Impatto: Applicazioni vedono upload/download più veloci Copia di file SMB tra Redmond e Australia aumenta di 10x Backup tra la bay area e il Data Center a Tukwila aumenta di 40x I benefici variano a seconda del networking (Schede di rete – Congestione dei Router)

17 Performance delle applicazioni con Windows Vista/Windows Longhorn Server tra Redmond e Sydney
Throughput (Mbps) Per lo scenario di sharepoint tra Win 2003 Server e Vista client, bisogna modificare una chiave di registry sul server Win 2003 modificare "MaxBytesPerSend" HKLM\System\CurrentControlSet\Services\HTTP\Parameters to value 0xFFFFF

18 Miglioramenti dei Protocolli: SMB 2.0, Transactional File I/O
SMB 2.0 aumenta le costanti per il file sharing (utenti, file aperti, numero di share, ecc.) Supporta l’invio di comandi multipli nello stesso pacchetto SMB Supporta buffer più grandi Supporta handle durevoli, link e semplifica gli algoritmi di firma Transactional File I/O (TxF) Il transaction framework del kernel, in Windows Server 2008, è stato esteso nel SO (DB, registry, file system, ecc.) per garantire che le operazioni di I/O abbiano successo o falliscono nella loro interezza. Il transaction framework del kernel è stato migliorato per garantire i requisiti di performance di operazioni più grandi o più complesse Benefici Miglioramento del protocollo fornisce nuove funzionalità di storage

19 40X Window Auto-Tuning Replica di data tra Redmond e la Bay Area
3/27/2017 2:28 AM Window Auto-Tuning Replica di data tra Redmond e la Bay Area Link dedicato con banda di 1Gbps Configurazioni di Default Su Windows Server 2003 SP1: 100Mbps NICs, 10Mbps throughput Su Windows Longhorn Server: 100Mbps NICs, 80Mbps throughput 1000Mbps NICs, 400Mbps throughput (Copia memory to memory) File copy disk to disk è limitato a 250Mbps perchè il disco diventa il collo di bottiglia 40X MICROSOFT CONFIDENTIAL © 2006 Microsoft Corporation.

20 Limiti del protocollo: gestione della banda molto ampia
Scenario: Replica tra data center geograficamente distribuiti connessi da link gigabit Il protocollo TCP (controllo della congestione) taglia drasticamente il sending rate in caso di perdita di pacchetti e aumenta il sending rate lentamente < 1 in packet loss rate per occupare completamente una banda di 1Gbps/100ms link Soluzione: Compound TCP utilizza informazioni sulla latenza per diminuire il sending rate senza causare perdita di pacchetti Evitare traumi: impatto sulle connessioni esistenti è <10% Può essere abilitato per default su Windows Longhorn server (è necessario solo il supporto lato send) Impatto: replica tra i data center più veloce Tempo di replica di ridotto della metà

21 Esempio: CompoundTCP Performance

MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

22 Limiti del protocollo: Gestione dei Random Losses
Scenario: Reti Wireless come GPRS, UMTS, WLAN Perdita di pacchetti è interpretata da TCP come indice di congestione Link layer recovery peggiora i problemi poichè il TCP effettua il recovery al proprio livello (spurious retransmissions) Grossi cambiamenti in Round Trip Times (RTT) causano (packet retransmission e) perdita di connettività TCP Soluzione: Detection delle spurious retransmissions usando i meccanismi di Forward Retransmission Timeout Recovery (FRTO) e Delayed Selective Acknowledgement (DSACK) (IETF based) Evitano le ritrasmissioni non necessarie e evitano anche la riduzione del sending rate Meccanismo elastico di gestione del RTT Impatto: migliorate le performance wireless Miglioramento del 10-30% del throughput scenari in GPRS

23 Detection dei limiti delle performance del TCP: TCP Analyzer
3/27/2017 2:28 AM Scenario: difficile diagnosticare problemi di performance di Rete Può essere nella rete nell’invio o nella ricezione Statistiche per connessione non sono facilmente disponibili Soluzioni: Supporto per statistiche TCP estese Statistiche TCP estese per connessione in tempo reale Disabilitate per default, abilitate per-connessione TCP Analyzer Tool grafico che mostra le statistiche selezionate Mostra automaticamente I colli di bottiglia per le performance MICROSOFT CONFIDENTIAL © 2006 Microsoft Corporation.
