Building a Dynamic Cloud Environment

1 Dynamic Cloud Solution Reference Architecture Building a Dynamic Cloud Environment The goal of this reference architecture is to provide IT management, architects, and designer s insight to configurations used to build a cloud infrastructure. The architectural design and configurations in this paper should not be construed as fully tested, qualified and supported configurations. Rather it is simply as an example and proof point of what can be built. To implement such an infrastructure, please consult with your local Fujitsu, NetApp and Brocade representatives Powered by: Jose Carreon OEM Marketing

2 DYNAMIC CLOUD ARCHITECTURE To validate that a combination of our products could support a cloud-like infrastructure, Fujitsu, NetApp, and Brocade joined together to validate a solution. The following paragraphs showcase the elements and efforts to achieve our solution. Key Technology Elements For technical competence and flexibility, we choose remote hypervisor boot over FCoE. VMware s hypervisor was used for this architecture because it provides excellent virtual switch management and integration into NetApp and Brocade network management. VMware is currently the market leader and has been showcased in other Cloud scenarios. This solution also runs Microsoft s Hyper-V in parallel as most end-users would see benefit of having both industry leader s virtualization products based on their respective strengths. Fujitsu PRIMERGY CX1000 or RX Series (RX200) as the server platform For the CX1000 we used CX120 node equipped with a Brocade 1020 dual port CNAs Brocade 8000 as Top of Rack 10G CEE switch and as potential bridge into FC SAN Brocade MLX and Brocade MLX-4 chassis as aggregation level / core switch NetApp FAS 3140A Storage Arrays with UTA (Universal Target Adapters) Fujitsu ETERNUS FC storage as alternative to the NetApp storage Other optional equipment used: Fujitsu ETERNUS FC storage as alternative to the NetApp storage Brocade 300 FC SAN switch Brocade FWS 624 IP switch Brocade FCX-S 648 IP switch Fujitsu, Brocade, and NetApp Management products Principle Design Concept Open Cloud Infrastructure 2 of 8

3 Given the above listed components, the fundamental structure is defined by the 24 port Brocade 8000 FCoE switch and the taken oversubscription ratio. This leads to basic building blocks of at maximum 16 to 20 servers, which are connected to two Brocade 8000 switches to provide redundant connection to each server. At the north side of the Brocade 8000, Ethernet and Fibre Channel, traffic is split and forwarded to 10 GbE LAN and 8 Gb FC SAN switches. This architecture is extremely scalable as nearly any number of these building blocks can be connected to appropriate LAN and SAN switches without adding management complexity. As an alternative, an end user can utilize NetApp s storage arrays with their UTA (Universal Target Adapter) allowing direct connection to FCoE. In smaller configurations, this provides the option of omitting the entire FC network. These two architectures were developed and tested, one at Fujitsu in Paderborn, Germany and one at Brocade in San Jose, CA; each with a different focus by using different server nodes and network oversubscription. The Fujitsu Paderborn architecture was focused on efficiency in every respect like space, energy and cost, and was built around the Fujitsu PRIMERGY CX1000. The San Jose architecture was focused on performance and higher throughput through less oversubscription. This architecture utilized Fujitsu PRIMERGY RX200 server nodes. Another aspect of the second architecture is that it may be a base for initial customer installations or used for evaluation purposes. It is more flexible in the number of nodes and therefore can be less expensive compared to the larger PRIMERGY CX1000 configuration. Open Cloud Infrastructure 3 of 8

4 FUJITSU CONFIGURATION This instance is based on the Fujitsu PRIMERGY CX1000 cloud server hardware. The 38 servers are divided into two groups, the upper 19 servers are connected to the upper two Brocade 8000 switches, the lower 19 servers are connected to the lower two Brocade 8000 switches. The following picture shows the customer data network only. The management network is described further down in this paper. The NetApp FAS3140A is directly connected via FCoE by two ports to each of the 4 Brocade8000s. With efficiency as this architecture s focus, there is only a three port LAG used for connecting the Brocade 8000 to the MLX switch. The FAS 3140A Array is connected by 2 ports to each Brocade Open Cloud Infrastructure 4 of 8

5 SAN JOSE CONFIGURATION This instance is based on Fujitsu PRIMERGY RX200 servers and being focused more on IO performance and throughput was configured with an oversubscription of 2:1. An added benefit of this design is the flexibility of changing the oversubscription to meet an end user s specific requirements. The following picture shows the customer data network only. The management network is described further down in this paper. The NetApp FAS3140A is directly connected through FCoE by two ports to each of the two Brocade 8000 switches. There is a four port LAG used for connecting the Brocade 8000 to the MLX -4 switch. The FAS 3140A Array is connected by two ports to each Brocade Open Cloud Infrastructure 5 of 8

6 TRADITIONAL FC SAN ALTERNATIVE Alternatively to the NetApp FCoE-connected storage a Fujitsu ETERNUS storage system can be utilized. The Brocade 8000 additionally provides eight FC ports which can connect storage to the PRIMERGY CX1000 rack. The ETERNUS FC storage is connected through a Brocade 300 switch to the FC ports on the Brocade 8000 switches. BROCADE 8000 SWITCH HIGHLIGHTS Delivers Data Center Bridging (DCB) and Fibre Channel over Ethernet (FCoE) for top-ofrack server I/O consolidation Offers deployment flexibility, initially as a Layer 2 Ethernet switch with Fibre Channel capabilities activated later, or as a fullfunction DCB/FCoE switch Utilizes a cut-through, non-blocking architecture to deliver line-rate performance across twenty-four 10 Gbps DCB ports with eight 8 Gbps Fibre Channel ports Provides rich Layer 2 Ethernet functionality for LAN traffic and advanced Fibre Channel functionality for SAN traffic Utilizes Brocade Link Aggregation Control Protocol (LACP) and Brocade frame-based trunking to maximize network bandwidth Improves energy efficiency, operating at 350 watts with redundant power supplies and cooling fan FRUs Combines with Brocade Converged Network Adapters (CNAs) and Brocade Data Center Fabric Manager (DCFM ) to provide a unified DCB/FCoE solution that reduces capital and operating expenses Brocade 8000, CNAs, and Brocade Fibre Channel SAN infrastructures can be managed by Brocade DCFM as part of a unified DCB/FCoE Open Cloud Infrastructure 6 of 8

7 MANAGEMENT INFRASTRUCTURE FOR BOTH CONFIGURATIONS For testing purposes we chose a separate management LAN A Brocade FWS switch was used as the core of the management network. The central management station hosting all the management software is connected to it, as well as the dedicated (out-ofband) management ports of nearly all the other components (except FCX-S). This allows the administrator to manage the infrastructure out-of-band, entirely independent of the customer production network. Each server node s BMC (Baseboard Management Controller) is connected to the first onboard NIC (LoM) which itself is connected to a FCX switches working as ToR management switch. This in-rack 1 GbE management network provides both BMC-based out-of-band server HW management (like power on/off) and OS or hypervisor management for example (Vmotion) Management Software The Brocade FWS ran a DHCP server to provide IP configurations (within the management network only) especially to the larger number of server nodes. The Central Management Station (CMS) will be a Fujitsu PRIMERGY RX200 with at least 16 MB of memory and a local disc to host the PRIMERGY ServerView Deployment and Operations Manager to install and operate the servers. Brocade DCFM network management product will be used to administer all switch components. VCenter will be used to manage the VMware Hypervisors and VMs on the server nodes. As long as there is only one NetApp FAS Array in the infrastructure the NetApp Operations Manager is not required, a single Array is managed by the FAS-built-in ONTAP management SW. In case of larger installation the NetApp OM would have to be additionally installed on the CMS. Open Cloud Infrastructure 7 of 8
