Today HP announced a new set of technology programs and future products designed to move x86 server technology for both Windows and Linux more fully into the realm of truly mission-critical computing. My interpretation of these moves is that it is both a combined defensive and pro-active offensive action on HP’s part that will both protect them as their Itanium/HP-UX portfolio slowly declines as well as offer attractive and potentially unique options for both current and future customers who want to deploy increasingly critical services on x86 platforms.
Bearing in mind that the earliest of these elements will not be in place until approximately mid-2012, the key elements that HP is currently disclosing are:
ServiceGuard for Linux – This is a big win for Linux users on HP, and removes a major operational and architectural hurdle for HP-UX migrations. ServiceGuard is a highly regarded clustering and HA facility on HP-UX, and includes many features for local and geographically distributed HA. The lack of ServiceGuard is often cited as a risk in HP-UX migrations. The availability of ServiceGuard by mid-2012 will remove yet another barrier to smooth migration from HP-UX to Linux, and will help make sure that HP retains the business as it migrates from HP-UX.
Analysis engine for x86 – Analysis engine is internal software that provides system diagnostics, predictive failure analysis and self-repair on HP-UX systems. With an uncommitted delivery date, HP will port this to selected x86 servers. My guess is that since the analysis engine probably requires some level of hardware assist, the analysis engine will be paired with the next item on the list…
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.
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
