Pick a flavor of Fedora streamlined for your needs, and get to work right away.
Cisco Validated Designs consist of systems and solutions that are designed, tested, and documented to facilitate and improve customer deployments. These designs incorporate a wide range of technologies and products into a portfolio of solutions that have been developed to address the business needs of our customers.
Typically configured in pairs for redundancy, two fabric extenders provide up to 160 Gbps of I/O to the chassis. Each Cisco UCS 2208XP has thirty-two 10 Gigabit Ethernet ports connected through the midplane to each half-width slot in the chassis. The Cisco UCS 2208XP Fabric Extender (Figure 4 ) has eight 10 Gigabit Ethernet, FCoE-capable, Enhanced Small Form-Factor Pluggable (SFP+) ports that connect the blade chassis to the fabric interconnect.

Security updates have been issued by Debian (jackson-databind, leptonlib, libvorbis, python-crypto, and xen), Fedora (apache-commons-email, ca-certificates, libreoffice, libxml2, mujs, p7zip, python-django, sox, and torbrowser-launcher), openSUSE (libreoffice), SUSE (libreoffice), and Ubuntu (advancecomp, erlang, and freetype).
Rather, a direct API call to the NetApp storage system is utilized through the NetApp Unified driver that facilitates a controller-side copy relative to a network copy. If Cinder and Glance share the same NetApp FlexVol, the Copy Offload tool is not necessary.
By selecting the Boot from Image (Creates a New Volume) option in Nova, you can leverage the enhanced instance creation capabilities described previously. Normally volumes created as a result of this option are persistent beyond the life of the instance. A Glance instance image of 20GB can, for example, be cloned in 300ms using NetApp FlexClone technology. This can provide a significantly faster provisioning and boot sequence relative to the normal way that ephemeral disks are provisioned. In the normal way, a copy of the disk image is made from Glance to local storage on the hypervisor node where the instance resides. However, you can select the Delete on Terminate option in combination with the Boot from Image (Creates a New Volume) option to create an ephemeral volume while still leveraging the Rapid Cloning capabilities described in the section Rapid Cloning.
This converged I/O results in reduced cables, SFPs and adapters – reducing capital and operational expenses of overall solution. Unified Fabric —In Cisco UCS, from blade server chassis or rack servers to FI, there is a single Ethernet cable used for LAN, SAN and management traffic.
This prevents domain pollution of compute and network domains with virtualization when virtual network is managed by port-profiles defined by the network administrators’ team. Virtualization Aware Network —Cisco VM-FEX technology makes the access network layer aware about host virtualization. VM-FEX also off-loads hypervisor CPU by performing switching in the hardware, thus allowing hypervisor CPU to do more virtualization related tasks. VM-FEX technology is well integrated with VMware vCenter, Linux KVM and Hyper-V SR-IOV to simplify cloud management.
Therefore, your storage spends more time in an optimal performance mode that maximizes application productivity. DDP minimizes the performance drop that can occur during a disk rebuild, allowing rebuilds to complete up to eight times faster than with traditional RAID. Shorter rebuild times also reduce the possibility of a second disk failure occurring during a disk rebuild and protects against unrecoverable media errors. Stripes with several drive failures receive priority for reconstruction.
By unifying the storage access the Cisco Unified Computing System can access storage over Ethernet (SMB 3. · Network – The system is integrated onto a low-latency, lossless, 10-Gbps unified network fabric. Virtualization – The system unleashes the full potential of virtualization by enhancing the scalability, performance, and operational control of virtual environments. This provides customers with storage choices and investment protection. The unified fabric lowers costs by reducing the number of network adapters, switches, and cables, and by decreasing the power and cooling requirements. This network foundation consolidates LANs, SANs, and high-performance computing networks which are separate networks today. 0 or iSCSI), Fibre Channel, and Fibre Channel over Ethernet (FCoE). Cisco security, policy enforcement, and diagnostic features are now extended into virtualized environments to better support changing business and IT requirements. In addition, the server administrators can pre-assign storage-access policies to storage resources, for simplified storage connectivity and management leading to increased productivity. Storage access – The system provides consolidated access to both SAN storage and Network Attached Storage (NAS) over the unified fabric.
And underlying infrastructure components that OpenStack services use for inter-service communication and to save persistent data such as MariaDB database, and a message broker called RabbitMQ. OpenStack Environment consists of stateless, shared-nothing services such as Keystone, Glance, Swift, Nova, Neutron, Horizon, Heat, Ceilometer, etc.
