HP will use what little inventory it has left to fill backlogged orders first. It is unclear how long partners and users have already been waiting on these switches.
HP Networking’s market share has grown steadily this year while Cisco has seen its share of the Ethernet switching market decline 7%. HP’s growth has largely been due to competitively priced switches and lifetime warranties that Cisco can’t meet. But now some wonder whether that competitive pricing and increased market share also contributed to the current backlog.
One channel partner who works with both HP and Cisco believes the backlog is due to the same shortages that have hit many networking and wireless vendors. However, he confirmed a rapid growth in his company’s HP switch sales, which have been spurred by HP’s competitive pricing and customer push-back against Cisco’s SmartNet requirements.
Backlogged products include:
As an alternative to these switches, HP’s memo suggests users consider buying step-up switches in the same lines or the non-PoE equivalents.
HP did not return calls to for comment. In the memo, the company wrote that it is “working earnestly to pull in the delivery dates” from its supplier.]]>
A few months ago I reported about how vendors like Cisco and Check Point have created software that essentially extends the reach of physical firewalls into a server’s hypervisor. At the time, Juniper was developing the same capability by partnering with virtualization security startup Altor Networks. Not long after I wrote that story, Juniper bought Altor. Now just a couple months after the deal Juniper has announced that it’s integrated Altor’s technology with its firewalls, the SRX Series Services Gateway products. Juniper’s new vGW Virtual Gateway is a hypervisor-level firewall based on Altor’s technology. Network engineers can deploy vGW on every virtualized server in a data center and then manage and enforce security on the VMs on those servers through the SRX hardware.
“Typically we see the data center carved up into different [security] zones,” said Peter Lunk, director of product marketing at Juniper. “We’ve done integration so that the vGW can pull down zone information from the SRX and then it can populate and place individual VMs sitting on that server into the different zones assigned by the SRX. Then it can push that information up to the SRX. Now you can see all the way down to the VM level and see which virtual machines are sitting in which zone. Now [engineers] have control over whether you can move VMs in and out of those zones. And if you’re turning up a new VM, [engineers can control] which zone it needs to be attached to. If someone is trying to change the VM we have some control over that as well.”
A product like this gives network security engineers renewed visibility and control over what’s happening within virtual infrastructure. It should also have plenty of application in cloud computing environments as well.
The vGW can also mirror traffic within hypervisors up to the SRX so that the SRX can perform deep analysis on packets and basic reporting on any anomalies. Lunk said Juniper will expand on this mirroring capability in the future. He declined to offer details, but undoubtedly Juniper will add some automated security response features to the SRX for traffic mirrored by the vGW.
Lunk said Juniper has also done some engineering work to make Altor’s syslogs compatible with its own, so that the vGW can report into Juniper’s Security Threat Response Manager (STRM).]]>
TRILL and SPB promise to solve several architectural issues in data center networks today. Extreme aims to emulate just one of the benefits of the emerging standards. TRILL and SPB free up unused bandwidth in a network caused by spanning tree protocol (STP). STP prevents loops from forming in a network topology by closing off redundant paths. Those redundant paths only open if the primary link fails. TRILL and SPB allow all redundant links to be open, which allows Ethernet frames to take the shortest path to their destination. SPB and TRILL also allow multiple links to be in active-active mode, with data traffic aggregating across them.
Both TRILL and SPB are available today in a small amount of pre-standard products from some vendors. The use of TRILL and SPB will require hardware upgrades, so enterprises that want to benefit from the technology will have to replace their network infrastructure.
Extreme Networks has introduced a software upgrade across its switching portfolio that can give enterprises a portion of the functionality TRILL and SPB promises. And it delivers this capability without requiring new hardware.
Extreme has combined its Direct Attach Virtual Machine switching feature with its Multi-System Link Aggregation (M-LAG) feature to deliver a new “M-LAG Direct Attach” architecture. Basically, this software upgrade allows a customer to set pairs of upstream links in active-active mode, which enables upstream link aggregation.
“This provides enterprises the ability to have an active-active path in the data center today,” said Shehzad Merchant is the Senior Director of Strategy for Extreme. “Link aggregation technology has been around a long time. We’ve taken that technology and extend it. Now you can take a server with two NICs and bond those NICs with link aggregation and dual-home those into two upstream switches. If one switch or one NIC goes down, traffic automatically migrates to the second link. But if both are up, traffic aggregates across both those links.”
Unlike TRILL and SPB’s ability to work with arbitrary, multi-homed topologies, Exteme’s M-LAG Direct Attach only works with dual-homed links. M-LAG Direct Attach is also a proprietary technology, so you will need Extreme switches both upstream and downstream to make it work.]]>
Of the 100 attendees the analysts surveyed at the show 27% said they are already converging with NAS and iSCSI, 23% are planning to use NAS and iSCSI and 32% plan to use FCoE in the next three years. No one reported using FCoE today.
In the conversations I’ve had with data center and networking pros, it sounds like the convergence path a company takes will mostly depend on the infrastructure they already have in place. Fibre Channel shops will want to use FCoE in order to get more out of their storage area network investments. iSCSI shops will see no reason to invest in FCoE. They’ll just upgrade to lossless 10 Gigabit Ethernet and converge iSCSI and production traffic onto the same wire.]]>
