To achieve full high-availability and future easy scalability it’s recommended to use redundant external switches.The management network’s role is to provide internal logging, syslog mirroring and in some cases option for remote access.2.3FS8600 Primary Network (Client network)The “primary network”, also known as the client network, connects the FS8600 system to the customer network via gigabit Ethernet or 10GbE (depending on a model purchased) multiple ports.The “primary network” provides access to data from NFS and CIFS clients and also access to the NAS administration virtual IP (VIP).3Network Switches Configuration3.1Internal Switch ConfigurationThe FS8600 requires the internal network switch configuration to support the following configuration:VLANThe interconnect network must live on a dedicated VLAN that is isolated from all other traffic and solely purposed for an individual cluster’s interconnect traffic. This VLAN must be untagged on all switch ports connected to the FS8600 interconnect connectivity ports. MTUAll switch ports connected to FS8600 interconnect connectivity ports must be “enabled” for Jumbo Frames (MTU equal to or greater than 9000).Spanning TreeSpanning tree must be “disabled” for all FS8600 interconnect ports. For many network vendor implementations, this will be called “portfast” or “edge” in the switch configuration semantics.Flow ControlThe FS8600 requires that all switch ports connected to the FS8600 interconnect interfaces have flow control “enabled”.The following is an example of how to configure Dell Force10 switches and Dell PowerConnect series (the same commands are applied to Dell PowerConnect series)3.2Primary Switch ConfigurationThe FS8600 requires the primary network switch configuration to support the following configuration:VLANThe FS8600 primary network is VLAN-aware, meaning it is capable of understanding and communicating with VLAN tagged Ethernet frames, allowing it to address multiple networks across multiple VLANs at a time.VLAN TaggingIf only tagged VLANs will be used for management and data, the FluidFS controllers need to be able to communicate with each other on the Client Network using untagged traffic. In other words, even if there is not a subnet configured to use untagged traffic, the switch must still allow untagged traffic/packets to pass. Blocking untagged traffic can cause issues with FluidFS during maintenance activities such as service pack upgrades, and controller replacement.The switch must be configured properly in its present state, otherwise the untagged and/or tagged VLAN would not be accessible.On Dell PowerConnect switches, this correlates to setting all of the frontend network ports to general mode, and then allowing the specific VLAN tags that are to be allowed to pass through.On Force10 switches, this correlates to using hybrid port mode. General mode (Dell PowerConnect) and hybrid mode (Dell Force10) will permit untagged traffic to pass through in addition to the tagged VLANs you specifically allowed. DO not use trunk mode, as trunk mode will only pass tagged traffic, and will disallow untagged traffic.MTUThe FS8600 primary network supports Ethernet jumbo frames.Environments can expect a degree of performance improvement, particularly where throughput is concerned.To change the MTU value (Defaults is set to 1500) on the cluster from the FS8600 CLI, run the following command:Flow ControlIt is recommended, but not required, that all switch ports connected to the FS8600 “p rimary network” interfaces have flow control “enabled”.For more information regarding flow control and Storage Center, consult any Copilot Support Tech Alerts for the Storage Center configuration in question.Switch TopologyAn FS8600 appliance or cluster can only be as highly available or high performing as the switch infrastructure supporting it. Architecturally, three guiding principles can be used to construct a best practice switch connectivity topology:•Avoid any single points of failure•Ensure sufficient inter-switch throughput•Make every client connectivity port in an FS8600 cluster available to any potential clientALB and LACP ModeAn FS8600 appliance equipped with multiple network interface cards are bonded to sustain seamless link failure.FS8600 supports two bonding modes:∙Adaptive Load Balancing (ALB)∙Link Aggregation Control Protocol (LACP)The default bonding mode for the FS8600 is ALB which requires no switch configuration and exposes all bonded MAC addresses.For LACP, some switch configuration is required and only a single MAC address is exposed. The main benefit of using LACP in FluidFS is to reduce the number of required VIPs while maintaining efficient load balancing.Setting up LACP modeWhen setting LACP you will need to perform the following configuration changes:∙In FluidFS, set one primary network VIP per FS8600 controller.∙In FluildFS, set up the bonding mode to “LACP”.∙In the “primary network” switch, all switches must be stacks and define one LACP trunk per FS8600 controller.Figure 2: FS8600 LACP configuration.To change the default bonding mode from ALB to LACP from the FluidFS CLi:4 Load BalancingLocal Production SiteKATANA_11DNS server ApplicationserverFigure 3: FS8600 in a routed network diagram 4.1 Flat Network ConfigurationIn case of a flat network, meaning there are no Layer 3 switches or routers between the FS8600 and the clients on the primary network, the FS8600 will use an internal ARP-based load balancing mechanism.To achieve load balancing across multiple interfaces, the system uses a virtual IP and proxy ARP. This workload balancing method supports both inbound and outbound workloads.The proxy-ARP protocol enables a host to provide ARP responses on behalf of other hosts. In order to support this, the destination hosts need to be configured with the proxy IP address, but should not answer broadcast ARP requests for that address. The system uses arp-filter and arp-tables to “hide” the proxy address so unicast ARP and other traffic are still served.To verify that clients connecting to the FS8600 are balanced across all system controllers from the FS8600 CLI, run the following command:To verify a specific client connection to the FS8600, from the FS8600 CLI, run the following command (you will need to provide the client IP and the virtual IP used):4.2Routed Network ConfigurationSince ARP load balancing is only able to balance local network clients, the FS8600 utilizes DNS load balancing to balance clients connected across Layer 3 switches and routers.In essence the FS8600 storage system will serve several virtual IP addresses, based on the number of interfaces attached to the client network. The virtual IP addresses are distributed and balanced among the nodes and interfaces.The administrator defines these addresses as a round-robin group in the DNS server in the site. Clients use DNS lookup and thereby are balanced across all of the available nodes and NICs.When implementing a round robin DNS system, it is important to understand the caching relationships of all subsequent DNS systems between the round robin DNS server and the clients.For example, if ns0.local and ns1.local are configured for Round Robin DNS but clients use ns0.office.local as their primary DNS target, ns0.office.local could possibly poll ns0.local to satisfy the request, but then cache the request and return the same value to the next client, hence removing the benefit of implementing Round Robin DNS. Some environments may see a benefit in keeping a short TTL value for the relevant DNS records for added overall flexibility.When allocating IPs and creating “A” record pools for round robin DNS, there should be at a minimum as many IPs and associated “A” records as there are interfaces in the FS8600 cluster.4.3Routed Network and Static RoutesRouted networks provide an opportunity to enhance performance through a feature called static routes. This feature allows you to configure the exact paths in which the FS8600 storage system communicates with various clients on a routed network.To add a static route via the FS8600 CLI run the following command:5Additional Subnets5.1Additional SubnetsThe FS8600 is capable of supporting or living on large numbers of separate or distinct networks, also referred to as subnets. This can be beneficial for reasons such as consolidating established or legacy file servers, as well as following best practices for providing dedicated resources to specific client groups or environments.NDMP backups and replication should also be isolated to a dedicated network, and it is also suggested that where possible, networks should be isolated in a one to one fashion with VLANs.To add additional subnets you will need the following information:∙Subnet mask∙VLAN information, if applicable∙Private IPs – one IP per FS8600 controller∙Public IP – will be used as Virtual IP (VIP)6.1NTPThe FS8600 can use the NTP to poll time information from authoritative outside sources. Generally, it is recommended that a minimum of two sources be used. Three or more sources is the suggested configuration.For FS8600 environments that will be integrated with Active Directory, the NTP sources should be the Active Directory domain controllers for the domain in question.To configure the time server for the Active Directory environment please refer to the following link:/en-us/library/cc784800%28v=WS.10%29.aspxCluster QuorumIn the event that both the configured gateway and DNS hosts are unreachable, the ability to reach the configured NTP hosts is used as a cluster quorum voting mechanism. Because this mechanism is used in the event that DNS is unreachable, at least one of the time servers should be configured by IP as opposed to DNS.7.1Firewalled EnvironmentsMany enterprise organizations have various layers of security within their network, often at their border, across different branches and work groups. Firewalls are used to implement access restrictions and Individual rulesWhen deploying Dell F8600 in a firewalled environment we need to make sure that specific ports are allowing traffic.The list of ports are divided to two groups:∙Enterprise Manager and Data Collector ports∙FluidFS portsData Collector Inbound PortsData Collector Outbound PortsEnterprise Manager Client PortsFluidFS Basic PortsFluidFS Additional Ports (Depends on NAS environment and services):8Additional ResourcesBelow are some links to additional resources:Dell Compellent Documentation∙Dell Compellent Replay Manager 7 Administrator's Guide ∙Dell Compellent Enterprise Manager 6.3 Users Guide∙Dell Compellent Storage Center 6.3 Users Guide。

生产中心IP地址子网掩码网关192.168.12.30 255.255.255.0 192.168.12.254 控制器A(18517)控制器B(18518) 192.168.12.31 255.255.255.0 192.168.12.254管理IP地址192.168.12.29 255.255.255.0 192.168.12.254打开IE浏览器,输入管理IP地址,然后输入用户名及口令(默认:Admin/mmm)用户名认证通过后将进入图形管理界面的主界面。

二、逻辑卷管理1、创建卷文件夹卷文件夹用来将逻辑卷分组,例如可以同一个部门所有应用相关的逻辑卷放置在同一个卷文件夹下面以便管理。

操作如下:右键单击Volume,单击”Create Volume Folder”,之后设定卷文件夹名。

2、创建一个逻辑卷右键单击新创建好的卷文件夹,如果未创建卷文件夹则直接在“V olumes”下点击右键,选择”Create Volume”输入V olume的容量,由于Compellent的Dynamic Capacity精简配置功能,V olume可以设置超过存储物理空间的大小并分配给服务器。

但应考虑到不同类型的服务器能认到单个空间的最大值。

选择该卷的存储模板(Storage Profile),不同的Storage Profile定义了各个层级不同的RAID 类型组合。

Storage Profile的选择需要根根据现场情况确定。

选择该卷Replay的创建策略,如果不需要使用Replay功能则可以去掉Storage Profile的复选框。

确定V olume创建的各项参数后,点击“Create Now”如下所示,建立完成一个名为MAM的逻辑卷,且属于名为mam的卷文件夹。

三、服务器管理1、创建服务器文件夹服务器文件夹用来将服务器分组,例如同一个部门所有应用相关的服务器放置在同一个服务器文件夹下面。

操作如下:右键单击Server,单击”Create Server Folder”,之后设定服务器文件夹名。

2、创建一个服务器右键单击新创建好的服务器文件夹,单击”Create Server”3、绑定HBA卡或网卡(iSCSI方式)服务器与存储连接包括两种:直连或者通过交换机连接。

无论哪种,如果有多台服务器通过HBA卡连接到存储上,最好先将服务器上的HBA卡的WWN记录下来,以示分别。

当连接(例如交换机的Zone)设置好后,单击”Create Server”后端界面中,将会显示HBA 与存储控制器连接的列表。

根据HBA卡的WWN进行选择,之后设定服务器名。

四、逻辑卷映射服务器1、映射LUN右键单击逻辑卷,如下图显示,选择”Map Volume to Server”从服务器树上显示要映射到的服务器名,如下图显示,选择”MDC”选择该映射经过的存储控制器端口。

如果有两个端口,表示有两条路径连接着逻辑卷和服务器,需要在服务器安装MPIO(多路径管理)软件。

Compellent提供免费的MPIO软件。

由于多路径实际指向的逻辑卷是相同的,所以该映射相关的LUN ID也相同,例如,下图中两个连接的LUN ID都为0。

2、识别LUN进入到服务器所在操作系统的界面,如下图所示,进入Windows的计算机管理界面。

在左边选择”设备管理器”,右边的树根(如此处的MDC)上单击右键,选择”扫描检测硬件改动”之后可识别到新的盘,分配盘符,分区、格式化后,就可像服务器本地硬盘一样使用了。

五、持续数据保护(数据即时回放,Data Instant Replay) Replay的创建有两种方式,一种是手动立即创建,另一种是通过Replay的模板来创建1、创建Replay Profiles右键单击Replay Profiles,选择Create Replay Profiles出现下图所示,在Name处设定Replay模板的名称,单击”Add Rule”出现下图所示,用户可以设置Schedule的类型,生成一次(Once)保护点,或是按天(Daily)、按周(Weekly)、按月(Monthly)例如,下图生成一次保护点,可以设定某年某月某天的某个时刻生成保护点再如,下图是按照每天生成若干个保护点。

可以设定时间段,在这个时间段里每隔多长时间(可以是每隔几分钟,或者每隔几个小时)。

下图是,早上6点到下午6点之间,每隔3小时生成一个保护点。

与此同时,用户还可以设定该保护点过期的时间,如下图1天过期,释放保护点所占据的空间一个Replay模板可以添加多个规则,如下图所示,名为Test Replay Profile的有两个规则,1) 每天都晚上8点生成一个保护点,1小时后过期;2) 每周的周一、周二周三和周五晚8点创建一个保护点,一周后保护点过期2、将Replay Profile应用至数据卷右键单击Replay模板,选择”Apply to Volume(s)”一个Replay模板可以同时施加到多个逻辑卷上五、逻辑卷模板(Storage Profiles)默认的逻辑卷模板为Recommended(All Tiers),此种模板创建的逻辑卷能跨越所有层(不同转速的盘),新的数据以及访问频繁的数据放置在Tier1上,那些很少访问,甚至不被访问的历史数据沉淀到Tier 2,再放置到Tier 3上。

系统自定义的Storage Profiles除了Recommended 外,还有High Priority(Tier 1),Medium Priority(Tier 2),Low Priority(Tier 3)。

用户可以自己创建新的Storage Profile。

右键单击Storage Profile,选择Create Storage Profile。

Writable Data指的是生产卷新写入的数据,Replay Data指的是保护点更改的数据。

如下图所示,用户可以自行定义Writable Data和Replay Data的层级和RAID类型。

例如,用户希望数据无论访问频繁与否,都需要有最快的响应,这样可以只将Tier Storage 的Raid 10的复选框勾选上。

第二章主要功能介绍注:此处只列出三个重要功能,除了这些功能之外还有许多丰富强大的功能,例如企业级容灾(精简复制)、Copy/Mirror/Migrate、Virtual Ports、Server Instant Replay、用户角色管理等等,更多内容参见Storage Center XX.XX User Guide.PDF。

一、高级精简配置(Dynamic Capacity)Compellent Storage Center的动态空间技术只在实际写入数据时才消耗空间,而且能够提供比实际物理空间大得多的逻辑卷空间,解决了传统SAN存储扩容需停机的问题,而且规划和管理及其简单。

如下图所示,选择逻辑卷MAM,在右边单击标签”General”,可以看到其Size大小为1.2TB。

单击标签”Statistics”后,可以发现实际占据的物理空间为0MB,如下图显示。

这是因为,在映射到服务器并格式化之前,逻辑卷并没有写入实际数据,格式化后,实际占据的物理空间也不过一百多MB,这是因为写入了一些元数据信息。

拷入文件,也即实际写入数据后,实际占据的物理空间随之增长。

如下图所示,经过一段时间后,2.5GB多的文件,因为采用的是RAID10,实际占据了5.12GB的物理空间。

二、保护点恢复MAM逻辑卷,做为共享盘映射到其他服务器上,上面有userclips文件夹,现在为MAM逻辑卷施加了每个两分钟做保护点的Replay Profile。

之后,删除整个userclips文件夹,如下图所示如下图所示,文件夹已被彻底删除选择逻辑卷MAM删除文件夹之前生成的保护点,单击右键,选择Local Recovery,这样便可生成一个可映射到服务器的保护卷。

设定Local Recover的名称后,选择与该保护卷映射到服务器,如下图显示的MDC服务器。

映射建立好之后,为保护卷对应的盘添加盘符,可查找到userclips文件夹下所有文件,将这些文件拷入原盘相应文件夹,便完成了恢复操作。

也可采用另一种恢复方式,将保护卷替换源卷,操作方式如下:1、记录源卷的在服务器里的盘符,以及在存储管理界面里连接的LUN ID,将源卷与服务器的映射方式去除2、将保护卷映射到服务器,注意采用源卷的LUN ID3、为保护卷添加源卷的盘符第三章MPIO软件Compellent提供免费的MPIO软件,也推荐使用操作系统内嵌的MPIO软件。

对于Windows 2008,其内嵌了MPIO功能,使用起来非常方便。

如果一个逻辑卷有多条路径映射到服务器,例如通过多控制器端口,或通过服务器的多个HBA卡端口,需要增加MPIO功能:1.打开服务器管理器:开始->程序->管理工具->服务器管理器选择功能,单击“添加”功能,选择“多路径”,单击下一步后,会询问你是否确认安装多路径,并提醒在安装完成后,需要重新启动服务器。
