hp customer case study: considerations for choosing a converged infrastructure vendor
DESCRIPTION
Hospital Sírio-Libanês was preparing to modernize its data center infrastructure to pave the way for growth. The Brazilian hospital aimed to be a center of medical excellence, so it sought a solid technology foundation that’s both agile and flexible. To achieve this, the Sírio-Libanês IT team put together a project plan where they carefully evaluated potential vendors. This presentation reviews what the team learned from this process, and why Sírio-Libanês ultimately chose HP for its future data center infrastructure needs over Cisco, its incumbent network vendor.TRANSCRIPT

Major Cisco Proprietary Protocols under use

Transition Strategies (EIGRP to OSPF) Flash Transition / Overlay 1. Configure OSPF on the network with a low routing priority. 2. Verify the routing information taking into account that the routes may not
match if the EIGRP design used multiple summarization points. 3. Raise the OSPF routing priority (in all the routers at once)
The routing table should now contain only OSPF routes.
4. Remove EIGRP from the network. Coexistence (Redistribution using existing C6500) •Configure mutual redistribution at the border between OSPF and EIGRP regions of the network.
– Coexistence may be temporary while different areas are transitioned.
© Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 35
Transition Strategies (HSRP to VRRP)
Flash Transition / Overlay • HPN supports the standards-based Virtual Router Redundancy Protocol (VRRP), not Cisco’s
proprietary Hot Standby Router Protocol (HSRP).
• This does not mean that either protocol is inferior. However, interoperability dictates a plan that implements standard protocols.
• Although HSRP and VRRP share the same concepts, they are incompatible. In other words, there is no co-existence between them.
• VRRP is fully supported by HPN, Cisco, and other vendors, and should be implemented wherever possible.
• IRF on the core eliminates the need for VRRP
© Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 36
Transition Strategies: CDP to LLDP
Coexistence
• Reason: Using Cisco IP Telephony Solutions
• LLDP-enabled device cannot recognize CDP packets and doesn’t respond to requests from Cisco IP phones for the voice VLAN ID configured on the device. This causes a requesting Cisco IP phone to send voice traffic without any tag to the device, which disables the ability to differentiate VOIP traffic from lower priority traffic (such as best effort).
• You can configure CDP compatibility mode on HPN devices to allow LLDP to receive and recognize CDP packets coming from Cisco IP phones, and configure the voice VLAN automatically. VOIP traffic can then be confined in the configured voice VLAN and differentiated from other types of traffic.

PVST was developed by Cisco to overcome limitations in the standards-based Spanning Tree Protocol (802.1d) • PVST is a Cisco proprietary protocol and it uses the also proprietary ISL VLAN identification mechanism
• PVST+ is a variation of PVST and uses the IEEE VLAN ID
PVST exist because when implementing STP in a multi-VLAN environment it is convenient to have several spanning trees in order to create VLAN load balancing.
PVST/PVST+ Weaknesses:
• Max of 128 STP instances on Cisco switches. Each VLAN will use an instance on PVST+, thus max of 128 VLAN per bridge region.
• Not suitable for DC ; Not enough VLANs; Huge impact due to flooding during frequent adds/deletes/updates.
• Uses more processing power on switch, more bandwidth and complexity
Per-VLAN Spanning Tree - PVST and PVST+
© Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. 38
• HP Legal approved support of Cisco PVST+ interoperability mode in Comware (December 2010)
• PVST+ is being added as part of the HP software update of existing switches, and is in the base software of new switches.
• With both Core and Distribution layer operating on IRF mode, the access layer may use link aggregation control protocol (LACP) instead of PVST+ for traffic load balancing.

LACP is a open standard developed by IEEE, and it offers all the features of Cisco’s proprietary PAgP protocol. LACP is fully supported by both Cisco and HPN, and should be implemented where ever possible http://www.cisco.com/en/US/technologies/tk652/tk701/technologies_white_paper0900aecd80422c70_ns165_Networking_Solutions_White_Paper.html
