Not to be left out of the announcement fever that has gripped vendors recently, Cisco today announced several updates to their UCS product line aimed at easing potential system bottlenecks by improving the whole I/O chain between the network and the servers, and improving management, including:
Improved Fabric Interconnect (FI) – The FI is the top of the UCS hardware hierarchy, a thinly disguised Nexus 5xxx series switch that connects the UCS hierarchy to the enterprise network and runs the UCS Manager (UCSM) software. Previously the highest end FI had 40 ports, each of which had to be specifically configured as Ethernet, FCoE, or FC. The new FI, the model 6248UP has 48 ports, each one of which can be flexibly assigned as up toa 10G port for any of the supported protocols. In addition to modestly raising the bandwidth, the 6248UP brings increased flexibility and a claimed 40% reduction in latency.
New Fabric Extender (FEX) – The FEXC connects the individual UCS chassis with the FI. With the new 2208 FEX, Cisco doubles the bandwidth between the chassis and the FI.
VIC1280 Virtual Interface Card (VIC) – At the bottom of the management hierarchy the new VIC1280 quadruples the bandwidth to each individual server to a total of 80 GB. The 80 GB can be presented as up to 8 10 GB physical NICs or teamed into a pair fo 40 Gb NICS, with up to 256 virtual devices (vNIC, vHBA, etc presented to the software running on the servers.
After considerable speculation and anticipation, VMware has finally announced vSphere 5 as part of a major cloud infrastructure launch, including vCloud Director 1.5, SRM 5 and vShield 5. From our first impressions, it is both well worth the wait and merits immediate serious consideration as an enterprise virtualization platform, particularly for existing VMware customers.
The list of features is voluminous, with at least 100 improvements, large and small, but among the features, several stand out as particularly significant as I&O professionals continue their efforts to virtualize the data center, primarily dealing with and support for both larger VMs and physical host systems, and also with the improved manageability of storage and improvements Site Recovery Manager (SRM), the remote-site HA components:
Replication improvements for Site Recovery Manager, allowing replication without SANs
Distributed Resource Scheduling (DRS) for Storage
Support for up to 1 TB of memory per VM
Support for 32 vCPUs per VM
Support for up to 160 Logical CPUs and 2 TB or RAM
New GUI to configure multicore vCPUs
Storage driven storage delivery based on the VMware-Aware Storage APIs
Improved version of the Cluster File System, VMFS5
Storage APIs – Array Integration: Thin Provisioning enabling reclaiming blocks of a thin provisioned LUN on the array when a virtual disk is deleted
Swap to SSD
2TB+ LUN support
Storage vMotion snapshot support
vNetwork Distributed Switch improvements providing improved visibility in VM traffic
vCenter Server Appliance
vCenter Solutions Manager, providing a consistent interface to configure and monitor vCenter-integrated solutions developed by VMware and third parties
Revamped VMware High Availability (HA) with Fault Domain Manager
HP this week really stirred up the Converged Infrastructure world by introducing three new solution offerings, one an incremental evolution of an existing offering and the other two representing new options which will put increased pressure on competitors. The trio includes:
HP VirtualSystem - HP’s answer to vStart, Flex Pod and vBlocks, VirtualSystem is a pre-integrated stack of servers (blade and racked options), HP network switches and HP Converged Storage (3Par and Left Hand Networks iSCSI) along with software, including the relevant OS and virtualization software. Clients can choose from four scalable deployment options that support up to 750, 2500 or 6000 virtual servers or up to 3000 virtual clients. It supports Microsoft and Linux along with VMware and Citrix. Since this product is new, announced within weeks of the publication of this document, we have had limited exposure it, but HP claims that they have added significant value in terms of optimized infrastructure, automation of VM deployment, management and security. In addition, HP will be offering a variety of services and hosting options along with VirtualSystem. Forrester expects that VirtualSystem will change the existing competitive dynamics and will result in a general uptick of interest it similar solutions. HP is positioning VirtualSystem as a growth path to CloudSystem, with what they describe as a “streamlined” upgrade path to a hybrid cloud environment.
Having attended the OpenStack Design Summit this week and at the same time fielding calls from Forrester clients affected by the Amazon Web Services (AWS) outage, an interesting contrast in approaches bore out. You could boil it down to closed versus open but there’s more to this contrast that should be part of your consideration when selecting your Infrastructure as a Service (IaaS) providers.
The obvious comparison is that AWS’ architecture and operational procedures are very much their own and few outside the company know how it works. Not even close partners like RightScale or those behind the open source derivative Eucalyptus know it well enough to do more than deduce what happened based on their experience and what they could observe. OpenStack, on the other hand, is fully open source so if you want to know how it works you can download the code. At the Design Summit here in Santa Clara, Calif. this week, developers and infrastructure & operations professionals had ample opportunity to dig into the design and suggest and submit changes right there. And there were plenty of conversations this week about how CloudFiles and other storage services worked and how to ensure an AWS Elastic Block Store (EBS) mirror storm could be avoided.
The drum continues to beat for converged infrastructure products, and Dell has given it the latest thump with the introduction of vStart, a pre-integrated environment for VMware. Best thought of as a competitor to VCE, the integrated VMware, Cisco and EMC virtualization stack, vStart combines:
I’ve been getting a number of inquiries recently regarding benchmarking potential savings from consolidating multiple physical servers onto a smaller number of servers using VMs, usually VMware. The variations in the complexity of the existing versus new infrastructures, operating environments, and applications under consideration make it impossible to come up with consistent rules of thumb, and in most cases, also make it very difficult to predict with any accuracy what the final outcome will be absent a very tedious modeling exercise.
However, the major variables that influence the puzzle remain relatively constant, giving us the ability to at least set out a framework to help analyze potential consolidation projects. This list usually includes:
As someone who has been covering cloud computing since the dawn of Amazon’s Elastic Compute Cloud (EC2) I’m constantly in education mode about what is and isn’t cloud computing. To borrow an analogy from my Forrester colleague Ted Schadler’s keynote at last year’s IT Forum, the challenge is a lot like helping blind men discern an elephant through just the parts of the animal they can reach. One feels the trunk and declares it a cylindrical, yet hairy and warm snake. The other calls it a strong, tough and deeply rooted tree upon feeling its hind leg. Each examiner brings their own experience and context to the challenge as well as their own judgments, then leaps to the conclusion that best fits their desires.
Today, Google announced Google App Engine for Business, and integration with VMware’s SpringSource offerings. On Monday, we got a preview of the news from David Glazer, Engineering Director at Google, and Jerry Chen, Senior Director Cloud Services at VMware.
For tech industry strategists, this is another step in the development of cloud platform-as-a-service (PaaS). Java Spring developers now have a full platform-as-a-service host offering in Google App Engine for Business, the previously announced VMforce offering from salesforce.com, plus the options of running their own platform and OS stacks on premise or in virtual machines at service providers supporting vCloud Express, such as Terremark.
What’s next? IBM and Oracle have yet to put up full Java PaaS offerings, so I expect that to show up sometime soon – feels late already for them to put up some kind of early developer version. And SAP is also likely to create their own PaaS offering. But it’s not clear if any of them will put the same emphasis on portability and flexible, rich Web-facing apps that Google and VMware are.
So Google aims to expand into enterprise support – but will need more than the planned SQL support, SSL, and SLAs they are adding this year. They'll also need to figure out how to fully integrate into corporate networks, the way that CloudSwitch aims to do.
