Earlier this week at its Discover customer event, HP announced a significant set of improvements to its already successful c-Class BladeSystem product line, which, despite continuing competitive pressure from IBM and the entry of Cisco into the market three years ago, still commands approximately 50% of the blade market. The significant components of this announcement fall into four major functional buckets – improved hardware, simplified and expanded storage features, new interconnects and I/O options, and serviceability enhancements. Among the highlights are:
Direct connection of HP 3PAR storage – One of the major drawbacks for block-mode storage with blades has always been the cost of the SAN to connect it to the blade enclosure. With the ability to connect an HP 3PAR storage array directly to the c-Class enclosure without any SAN components, HP has reduced both the cost and the complexity of storage for a wide class of applications that have storage requirements within the scope of a single storage array.
New blades – With this announcement, HP fills in the gaps in their blade portfolio, announcing a new Intel Xeon EN based BL-420 for entry requirements, an upgrade to the BL-465 to support the latest AMD 16-core Interlagos CPU, and the BL-660, a new single-width Xeon E5 based 4-socket blade. In addition, HP has expanded the capacity of the sidecar storage blade to 1.5 TB, enabling an 8-server and 12 TB + chassis configuration.
In the latest evolution of its Linux push, IBM has added to its non-x86 Linux server line with the introduction of new dedicated Power 7 rack and blade servers that only run Linux. “Hah!” you say. “Power already runs Linux, and quite well according to IBM.” This is indeed true, but when you look at the price/performance of Linux on standard Power, the picture is not quite as advantageous, with the higher cost of Power servers compared to x86 servers offsetting much if not all of the performance advantage.
Enter the new Flex System p24L (Linux) Compute Node blade for the new PureFlex system and the IBM PowerLinuxTM 7R2 rack server. Both are dedicated Linux-only systems with 2 Power 7 6/8 core, 4 threads/core processors, and are shipped with unlimited licenses for IBM’s PowerVM hypervisor. Most importantly, these systems, in exchange for the limitation that they will run only Linux, are priced competitively with similarly configured x86 systems from major competitors, and IBM is betting on the improvement in performance, shown by IBM-supplied benchmarks, to overcome any resistance to running Linux on a non-x86 system. Note that this is a different proposition than Linux running on an IFL in a zSeries, since the mainframe is usually not the entry for the customer — IBM typically sells to customers with existing mainframe, whereas with Power Linux they will also be attempting to sell to net new customers as well as established accounts.
Last week it was Dell’s turn to tout its new wares, as it pulled back the curtain on its 12th-eneration servers and associated infrastructure. I’m still digging through all the details, but at first glance it looks like Dell has been listening to a lot of the same customer input as HP, and as a result their messages (and very likely the value delivered) are in many ways similar. Among the highlights of Dell’s messaging are:
Faster provisioning with next-gen agentless intelligent controllers — Dell’s version is iDRAC7, and in conjunction with its LifeCyle Controller firmware, Dell makes many of the same claims as HP, including faster time to provision and maintain new servers, automatic firmware updates, and many fewer administrative steps, resulting in opex savings.
Intelligent storage tiering and aggressive use of flash memory, under the aegis of Dell’s “Fluid Storage” architecture, introduced last year.
A high-profile positioning for its Virtual Network architecture, building on its acquisition of Force10 Networks last year. With HP and now Dell aiming for more of the network budget in the data center, it’s not hard to understand why Cisco was so aggressive in pursuing its piece of the server opportunity — any pretense of civil coexistence in the world of enterprise networks is gone, and the only mutual interest holding the vendors together is their customers’ demand that they continue to play well together.
I just spent several days at Dell World, and came away with the impression of a company that is really trying to change its image. Old Dell was boxes, discounts and low cost supply chain. New Dell is applications, solution, cloud (now there’s a surprise!) and investments in software and integration. OK, good image, but what’s the reality? All in all, I think they are telling the truth about their intentions, and their investments continue to be aligned with these intentions.
As I wrote about a year ago, Dell seems to be intent on climbing up the enterprise food chain. It’s investment in several major acquisitions, including Perot Systems for services and a string of advanced storage, network and virtual infrastructure solution providers has kept the momentum going, and the products have been following to market. At the same time I see solid signs of continued investment in underlying hardware, and their status as he #1 x86 server vendor in N. America and #2 World-Wide remains an indication of their ongoing success in their traditional niches. While Dell is not a household name in vertical solutions, they have competent offerings in health care, education and trading, and several of the initiatives I mentioned last year are definitely further along and more mature, including continued refinement of their VIS offerings and deep integration of their much-improved DRAC systems management software into mainstream management consoles from VMware and Microsoft.
After three days of cloudwashing, cloud-in-a-box and erector set private cloud musings at Oracle OpenWorld in San Francisco this week, CEO Larry Ellison chose day four to take the wraps off a legitimate move into cloud computing.
Oracle Public Cloud is the unification of the company's long-struggling software-as-a-service (SaaS) portfolio with its Fusion applications transformation, all atop Oracle VM and Sun hardware. While Ellison spent much of his keynote taking pot shots at his former sales executive and now SaaS nemesis, Salesforce CEO Mark Benioff, the actual solution being delivered is more of a direct competitor to Amazon Web Services than Force.com. The strongest evidence is in Oracle's stance on multitenancy. Ellison adamantly shunned a tenancy model built on shared data stores and application models, which are key to the profitability of Salesforce.com (and most true SaaS and PaaS solutions), stating that security comes only through application and database isolation and tenancy through the hypervisor. Oracle will no doubt use its own Xen-based hypervisor, OracleVM rather than the enterprise standard VMware vSphere, but converting images between these platforms is quickly proving trivial.
Last year at VMworld I noted Xsigo Systems, a small privately held company at VMworld showing their I/O Director technology, which delivereda subset of HP Virtual Connect or Cisco UCS I/O virtualization capability in a fashion that could be consumed by legacy rack-mount servers from any vendor. I/O Director connects to the server with one or more 10 G Ethernet links, and then splits traffic out into enterprise Ethernet and FC networks. On the server side, the applications, including VMware, see multiple virtual NICs and HBAs courtesy of Xsigo’s proprietary virtual NIC driver.
Controlled via Xsigo’s management console, the server MAC and WWNs can be programmed, and the servers can now connect to multiple external networks with fewer cables and substantially lower costs for NIC and HBA hardware. Virtualized I/O is one of the major transformative developments in emerging data center architecture, and will remain a theme in Forrester’s data center research coverage.
This year at VMworld, Xsigo announced a major expansion of their capabilities – Xsigo Server Fabric, which takes the previous rack-scale single-Xsigo switch domains and links them into a data-center-scale fabric. Combined with improvements in the software and UI, Xsigo now claims to offer one-click connection of any server resource to any network or storage resource within the domain of Xsigo’s fabric. Most significantly, Xsigo’s interface is optimized to allow connection of VMs to storage and network resources, and to allow the creation of private VM-VM links.
A project I’m working on for an approximately half-billion dollar company in the health care industry has forced me to revisit Hyper-V versus VMware after a long period of inattention on my part, and it has become apparent that Hyper-V has made significant progress as a viable platform for at least medium enterprises. My key takeaways include:
Hyper-V has come a long way and is now a viable competitor in Microsoft environments up through mid-size enterprise as long as their DR/HA requirements are not too stringent and as long as they are willing to use Microsoft’s Systems Center, Server Management Suite and Performance Resource Optimization as well as other vendor specific pieces of software as part of their management environment.
Hyper-V still has limitations in VM memory size, total physical system memory size and number of cores per VM compared to VMware, and VMware boasts more flexible memory management and I/O options, but these differences are less significant that they were two years ago.
For large enterprises and for complete integrated management, particularly storage, HA, DR and automated workload migration, and for what appears to be close to 100% coverage of workload sizes, VMware is still king of the barnyard. VMware also boasts an incredibly rich partner ecosystem.
For cloud, Microsoft has a plausible story but it is completely wrapped around Azure.
While I have not had the time (or the inclination, if I was being totally honest) to develop a very granular comparison, VMware’s recent changes to its legacy licensing structure (and subsequent changes to the new pricing structure) does look like license cost remains an attraction for Microsoft Hyper-V, especially if the enterprise is using Windows Server Enterprise Edition.
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
